Restoring Speech to
Tracheostomy Patients
Tracheostomies may be established as part of an acute or chronic illness, and intensive care nurses can take
an active role in helping restore speech in patients with tracheostomies, with focused nursing assessments
and interventions. Several different methods are used to restore speech, whether a patient is spontaneously
breathing, ventilator dependent, or using intermittent mechanical ventilation. Restoring vocal commu-
nication allows patients to fully express themselves and their needs, enhancing patient satisfaction and
quality of life. (Critical Care Nurse. 2015;35[6]:13-28)
This article has been designated for CE credit. A closed-book, multiple-choice examination follows this article,
which tests your knowledge of the following objectives:
1. Identify the potential effects of the inability to communicate for a patient with a tracheostomy
2. Examine methods to restore phonation for patients with a tracheostomy
3. Discuss the role of critical care nurses in restoring phonation
Tracheostomy is one of the most common procedures performed in critically ill patients
and is becoming more commonplace in the intensive care unit (ICU).1 Indications for
tracheostomy include prolonged intubation with unsuccessful weaning, management of
bronchial hygiene, obstruction of the upper airway, and airway protection.1,2 Patients
with head and neck trauma and/or surgery or those who have airways that cannot be
managed via endotracheal intubation may also require a tracheostomy. When the tracheostomy tube is
initially placed, the cuff at the distal end of the tube is infl ated to protect the airway and provide effective
ventilation.2 Because infl ation of the cuff does not permit the passage of air up through the larynx, the
patient cannot phonate (ie, produce speech sounds).3 The inability to communicate via speech places a
great amount of stress on an already critically ill patient. Patients with tracheostomies report feelings of
frustration, fear, anxiety, and powerlessness related to the loss of voice.3-5 Donnelly and Wiechula6 have
described how patients experience the loss of voice as a form of torture, more so than the physical dis-
comfort the patients feel from the tracheostomy or other procedures performed in the ICU.

For patients in the ICU, the inability to express them-
selves and to actively participate in their plan of care
can lead to depression, disengagement in their recovery,
and nonadherence with their therapeutic plan.4,7-9 A tra-
cheostomy tube, however, does not prevent phonation.
Phonation can enhance the ability of patients with a tra-
cheostomy to express their needs and wishes fully and
effectively, allowing the patients to participate in their
plan of care and converse with their loved ones.7, 9 Criti-
cal care nurses are in an ideal position to coach and guide
tracheostomy patients to phonate, but nurses may not be
aware of all the options available. In this article, we pro-
vide infor-
mation that
will enable
nurses to take
an active role in restoring phonation in these patients. We
review the different approaches to restore phonation in
patients with a tracheostomy, including patients who
are spontaneously breathing, are being treated with
intermittent mechanical ventilation, or are ventilator
dependent. An essential component of successful com-
munication is to determine what option or options are
most appropriate for a particular patient.
Forms of communication such as lipreading, writ-
ing, hand signals, and picture boards can be useful for
enabling patients to express basic needs but do not fully
encompass the reciprocal nature of human communica-
tion.4,7 Visual acuity, language barriers, literacy, physical
immobility or weakness, and cognitive deficit can impair
the effectiveness of these other forms of communication.3,5
Ideally, critical care nurses can facilitate nonverbal forms
of communication. Lipreading is a specialized skill and
may be difficult for many nurses to master.9 Coded eye
blinking, head and hand gestures, and nodding answers
to yes-no questions require collaboration with patients
and must be effectively communicated to other caregivers
in order to be consistent9; however, these activities can be
time-consuming and can cause efficiency problems in
caring for critically ill patients. A patient-specific commu-
nication plan should be made available to everyone inter-
acting with a patient; preferably the plan should be at
the patient’s bedside or in another centralized location.9
Even with the best intentions, lapses in care may occur,
causing patients distress and frustration with caregivers.
Methods to Restore Phonation for
Patients With a Tracheostomy
Sound is produced as air passes through the vocal
cords, causing the cords to vibrate.10 Medical complica-
tions of the pharyngeal, laryngeal, and tracheal struc-
tures, including glottic or subglottic edema, ulceration of
the vocal fold, vocal cord paralysis, tracheal stenosis, and
tracheomalacia, can affect the ability to create sound.
The tracheostomy tube itself can markedly obstruct the
trachea, causing poor airflow, increased airway resis-
tance, and increased work of breathing and can lead to
an inability to produce speech. Therefore, the ability
to create sound with a tracheostomy tube depends on
having an adequate supply of air reach the vocal cords
with a minimum of resistance. The diameter, length,
and type of tracheostomy tube play important roles in
avoiding complications and leading to greater success
in phonation. Changing one or all of these components
of the tracheostomy tube can lead to less airway resis-
tance and prevent respiratory distress and unsuccess-
ful phonation trials. Methods to restore phonation for a
patient with a tracheostomy will also vary, depending on
whether or not the patient is ventilator dependent, and,
if so, whether the patient is fully or partially dependent
on ventilator support. Methods of restoring phonation
for patients who are spontaneously breathing, are being
treated with intermittent mechanical ventilation, or are
fully ventilator dependent are summarized in Table 1.

facilitates speech
Special considerations
Before the cuff is defl ated, subglottic
suctioning should be performed to
prevent aspiration of secretions from

complications associated with the
high-pressure TTS cuffs
Leak speech can be used in a patient
who can tolerate cuff defl ation
Ventilator settings can be adjusted to
compensate for tidal volume loss and
to improve speech quality
Thorough suctioning before and

unsuccessful leak speech trial
Tube has a port attached to an air
source located above the cuff
Secretions may pool above cuff;
suctioning of secretions from air
port should be done as needed to
maintain patent airway and facilitate
good speech quality
Voice is adjusted by increasing airfl ow,
often 5-15 L/min, to achieve optimal
vocalization; humidifi ed airfl ow
should be provided to mitigate
against discomfort with higher

Phonation in Patients Who Are
Breathing Spontaneously
For patients with tracheostomies who are breathing
spontaneously and do not require mechanical ventila-
tion, 3 primary methods of phonation can be used:
cuff defl ation with digital occlusion of the tracheos-
tomy tube; capping; and use of a speaking valve. Before
any method of phonation is started, the patient’s phys-
ical and mental condition should be assessed to deter-
mine which method would be the most appropriate.
The patient must be attempting to communicate ver-
bally and must have intact cognitive function.8 The
ability to follow instructions and communicate any
diffi culty with breathing or phonation is important to
success.11 With any of the following methods, nurses
should closely monitor patients for signs and symp-
toms of respiratory distress, including breathing dis-
comfort, increased respiratory rate, use of accessory
muscles, inadequate chest infl ation or defl ation, and
diffi culty with air exchange.9 Assessing the work of
breathing is a better method to determine tolerance of
cuff defl ation, capping, or use of a speaking valve than
is measuring oxygen saturation.
Cuff Defl ation. Generally, a patient must be able
to tolerate cuff defl ation or have a cuffl ess tube in order
to phonate via any of the 3 primary methods.8,11 Defl a-
tion of the cuff causes airfl ow to be redirected around
the tracheostomy tube and up through the upper part
of the airway and may require a period of adjustment
for the patient. Pooled secretions above the cuff and
movement of the tube during cuff defl ation can cause
airway irritation, coughing, obstruction of secretions,
increased work of breathing, and shortness of breath,
which may lead to cardiorespiratory deterioration.
Therefore, verifying that emergency equipment is avail-
able, including suction equipment and a manual resus-
citation bag, is important.
Cuff defl ation can be an anxiety-fi lled experience for
a patient if it causes respiratory discomfort and distress.
Therefore, it is essential to provide adequate assessments
as well as proper coaching and preparation of the patient
before, during, and after cuff defl ation. The following
steps can help facilitate a successful cuff defl ation trial:
First, explain to the patient the steps that go into cuff
defl ation and the feelings that might occur. Second, ensure
the correct position of the patient and the tracheostomy

Cons
Risk for aspirating secretions is
high; tube may not be tolerated
because of small diameter of
fenestration, which may mark-
edly increase airway resistance
and result in diffi culty exhaling,
air trapping (auto-PEEP), and
decompensation
Tube is not tolerated in patients
with increased respiratory rate
and minute ventilation because
of anxiety and respiratory
distress due to uncomfortable
breathing during attempted
speech
System requires greater knowl-
edge and assessment skills
by staff in order to maximize
success and minimize patient’s
respiratory discomfort, anxiety,
and distress
Pros
A fenestrated tracheostomy tube
allows air to travel through the
fenestration above the cuff,
decreasing airway resistance,
improving airfl ow in the tra-
chea, and facilitating speech
The Blom tube has a fenestra-
tion just above the cuff to min-
imize risk of granulation tissue
Special considerations
Volumes may need to be adjusted on
the ventilator for exhaled volumes
lost through the upper part of the
airway
Fit requires an evaluation by a spe-
cialist to ensure that the fenestration
lies centrally within the trachea;
otherwise, granulation tissue may
grow into the fenestration
Secretions can also collect in the fen-
estration, so patient should receive
optimal humidifi cation with heated
aerosol
System uses a special speech cannula
with 2 valves; upon inhalation, the
fl ap valve opens, allowing air through
the tube; upon exhalation, the fl ap
valve closes and air moves through
the fenestration and through a bubble
valve
A special exhaled volume reservoir can
be used to minimize alarms indicat-
ing low exhaled volume

Proper clearance of secretions will

and cough, which can initiate
bronchospasm.
tube, with the head of the bed elevated to the best level
for breathing comfort and neutral position of the tra-
cheostomy tube to prevent airway irritation, coughing,
and obstruction.9 Third, explain to the patient the need
to suction the back of the throat to clear secretions that
may have pooled above the cuff. Of note, deep subglot-
tic suctioning will not always ensure complete removal
of secretions once the cuff is defl ated, and suctioning of
the mouth and the posterior part of the pharynx may
still be required. If the patient is able, have him or her
perform this step. Fourth, before the cuff is defl ated,
have the patient take a deep breath in to maximize air in
the lungs to promote a forceful cough if needed to clear
any secretions. Just after the patient takes a deep breath
in, and as he or she begins to exhale, completely defl ate
the cuff. After the cuff is defl ated, immediately suction
as needed through the tracheostomy tube and/or mouth
to clear the secretions that might have remained above
the cuff. While the cuff is defl ated, closely observe the
patient for any signs or symptoms of respiratory dis-
tress. Increase the fraction of inspired oxygen as needed;
cuff defl ation causes admixture of room air in patients
receiving oxygen therapy. Secretions and coughing also
may lower
oxygenation.
Continu-
ally reassure
the patient
through this
process to decrease anxiety. Proper clearance of secre-
tions is crucial to successful cuff defl ation and will pre-
vent triggers of airway irritation and cough, which can
initiate bronchospasm. A manual resuscitation bag
and suction devices should be at hand to stabilize the
patient’s condition if needed.
If cuff defl ation is not initially tolerated, despite
meticulous attention to proper procedure, another trial
with slow defl ation of the cuff, perhaps up to several
minutes, is recommended.12,13 If respiratory distress,
dyspnea, or shortness of breath occurs with cuff defl a-
tion, the cuff should be reinfl ated, and cuff defl ation
trials can be repeated at another time. Working side
by side with speech language pathologists and respi-
ratory therapists can ensure patients’ comfort, toler-
ability of cuff defl ation trials, and quality outcomes.11
After successful cuff defl ation, digital occlusion can be
attempted for vocalization.
Digital Occlusion. Digital occlusion of the tra-
cheostomy tube is used for patients who have a cuffl ess
tube or a cuffed tube with a fully defl ated cuff (Figure
1). When the cuff is infl ated, the only exit for air from
the lungs is out the tracheostomy tube. If the cuff is
infl ated and the tube is occluded, air cannot move in
or out of the lungs. Therefore, digital occlusion should
be performed only with the cuff completely defl ated. A
potential complication with a cuffed tube is the bulki-
ness of the defl ated cuff, which may cause an obstruc-
tion while the patient is attempting to breathe around
the tube.8 In this case, a smaller diameter tracheostomy
tube or a cuffl ess tube, if appropriate, can be used to
facilitate speech.7,8 After cuff defl ation, a gloved fi nger
of the caregiver or patient is placed over the opening of
the tube. This procedure will redirect air to the upper
part of the airway and allow the air to pass through
the vocal cords. Many patients lack the dexterity that
this method requires,12 but digital occlusion may be an
option for patients who may not be completely alert
and who may not tolerate capping. Before digital occlu-
sion, a patient’s ability to inhale and exhale around
the defl ated cuff must be assessed. If the patient has
any diffi culty, teaching him or her intermittent dig-
ital occlusion during the exhalation phase can facili-
tate speech.9 If a patient is unable to speak or exhale or
complains of shortness of breath or trouble breathing,
digital occlusion should be stopped.9
Capping. Occluding the opening of the tracheos-
tomy tube with a cap, plug, or cork is another means
of producing speech.8 The goal of capping is to prevent

air from entering and exiting through the tracheostomy
itself; all the airfl ow is redirected around the tube and
up to the vocal cords. When a tracheostomy tube is
capped, the patient is not breathing through the tube
at all, but completely around the tube (Figure 2). This
method requires the ability to tolerate cuff defl ation and
necessitates maximizing airfl ow around the tube. With
2 exceptions, cuffed tracheostomy tubes with defl ated
cuffs should never be capped.8,13 The bulk of the defl ated
cuff on most tracheostomy tubes creates a great deal of
resistance around the tube, potentially interfering with
optimal ventilation. The only cuffed tracheostomy tubes
that can be safely capped when defl ated are a properly fi t
fenestrated tube or a tight-to-shaft (TTS) tracheostomy
tube (Figure 3). With the TTS tube, the defl ated cuff fl at-
tens completely against the shaft of the tube and mimics
a cuffl ess tracheostomy tube.8,13 The safety implications
of both types of tubes are discussed later in this article.
Ensuring that the tube is an appropriate size, one that
easily allows airfl ow around it and through the upper
part of the airway is important,8 although ease of air-
fl ow may not be obvious initially. Tubes that have a large
outer diameter should be exchanged for ones with a
smaller diameter to allow easy airfl ow around the tube.
The increased resistance caused by a large tracheostomy
tube in the airway or one with a bulky defl ated cuff can
cause anxiety and respiratory distress, which can lead
to respiratory compromise.9 One serious complication
of capping is obstruction, with mucus buildup around
or within the tube; therefore, frequent monitoring is
essential, especially during the initial capping trials.8
The strength of a patient’s cough and ability to clear the
airway of secretions should be assessed before capping
is used. A patient with a strong cough might not be able
to fully clear the airway of secretions, especially if the
secretions are thick and tenacious, because they may be
“hanging up” around the tube. Assessment of respiratory
rate, oxygen saturation, color, and breathing pattern
during a trial are necessary. If any signs of distress or
desaturation are noted, the cap should be immediately
removed and the patient returned to the humidifi ed tra-
cheostomy collar or mask. Because the patient is breath-
ing around the tube when it is capped, oxygen should
be provided as needed by nasal cannula or face mask.8,13
These potential complications reinforce the need to
adequately assess a patient’s cognitive status in order
for the nurse to detect respiratory distress quickly.
Speaking Valve. Use of a speaking valve (Figure 4)
is different than capping because the device is a 1-way
valve that allows air to enter into the tracheostomy tube
but prevents air from being exhaled through it.7,8 A
speaking valve can only be used by patients who are able
to tolerate total cuff defl ation, or ideally have a cuffl ess
tube. While using the valve, the patient inspires through
the tube but exhales around it (Figure 5).8 Most speaking
valves are fl ap valves that are placed over the opening to
the tracheostomy tube. The fl ap opens during inhalation

and closes during exhalation. Closure of the fl ap on
exhalation allows the exhaled air to be directed through
the vocal cords, the upper part of the airway, and out the
mouth and nose. Because of this path, any supplemental
oxygen that is required should be delivered via a humid-
ifi ed tracheostomy collar when a speaking valve is used.8
If the tube or cuff diameter creates a marked obstruc-
tion in the trachea, the patient will be unable to exhale
freely, and the inability to exhale completely can create
adverse effects such as air trapping, lung hyperinfl ation,
and respiratory distress. Speaking valves should never
be placed on a tube with an infl ated cuff because infl a-
tion of the cuff prevents exhalation, potentially causing
barotrauma and other possibly fatal complications.1,9 A
wide range of speaking valves is available, each with its
own level of resistance and potential to increase work of
breathing.15
Table 2 lists several contraindications8,9,16-18 to use of a
speaking valve. Patients with poor pulmonary reserve and
severe lung disease may not be able to completely inhale
and exhale, and hypercarbia can develop; use of a valve
may not be appropriate for these patients. Also, patients
who have an unstable hemodynamic status, received a
total laryngectomy, have an infl ated cuff, or have a foam-
cuffed tube are not candidates for a speaking valve.18
Patients with copious thick secretions or with obstruction
of the upper part of the airway should not use a speaking
valve.11 Speech language pathologists or respiratory thera-
pists can be resources for determining when a patient may
be ready for trials with a speaking valve. Maintaining
effective communication between various care providers
is important to optimize speaking valve trials.11

or speaking valve, patients should be under close obser-
vation to detect signs or symptoms of respiratory dis-
tress. If respiratory distress or desaturation occurs, a
nurse should immediately remove the cap or valve, suc-
tion secretions as needed, and return the patient to use
of a high-humidity tracheostomy collar. The patient may
need to begin with short sessions of capping or using a
speaking valve (as short as 5 or 10 minutes), then gradu-
ally increase the duration, and progress toward continu-
ous use. However, overnight use of the Passy-Muir valve
is not recommended.8,18 Members of the health care team
should be aware of factors that can lead to a patient’s
inability to tolerate capping trials, such as inattention to
optimum positioning, accumulation of secretions, fail-
ure of the valve to open freely on inspiration, and/or
patient anxiety related to capping trials.
During use of a valve or a cap, promotion of effec-
tive coughing and mobility of secretions is important.
Some patients do not have an effective cough because of
neuromuscular disease or paralysis. With these patients,
optimal positioning such as elevating the head of bed are
important to maximize breathing comfort and respira-
tory muscle function. Nurses must be cognizant of any
clinical worsening in the patient’s overall status, includ-
ing during any capping periods. Any new indication of
respiratory distress should lead to immediate discontin-
uation of a capping trial. Proper humidifi cation with a
heated aerosol may be necessary to keep secretions thin-
ner and easier to cough out. Patients can be evaluated
for use of a smaller tube or decannulation when they can
tolerate continuous capping for at least 24 to 48 hours
and achieve an acceptable cough strength so that they
are able to cough out all their secretions.8,13
Alternative Methods of Phonation. Two other
methods of phonation in spontaneously breathing
patients may be used by long-term tracheostomy patients
in subacute care, home, or rehabilitation settings: the tra-
cheostomy button and the Speak EZ tracheal cannula.
Both of these devices eliminate the bulk of a tube within
the airway and maintain the patency of the stoma. Nei-
ther of these devices requires ties to secure it; therefore,
they both require custom fi tting to determine the exact
length of the stoma.
A tracheostomy button (Figure 6) is a device that
maintains the patency of the stoma in patients who may
require repeated tracheostomies or may need rehabili-
tation to improve overall strength and meet criteria for
decannulation. The tracheostomy button is a stent that
maintains patency of the stoma for a prescribed time,
after which the button can be removed, allowing closure
of the stoma. If frequent access to the airway is required
(eg, for suctioning), the button should be replaced with
a tracheostomy tube. The tracheostomy button consists
of 3 parts: the tracheal cannula, the closure plug, and
spacer rings (Figure 7) that are added to fi t the length
and width of the stoma exactly. When the closure plug is
placed into the cannula, the petals at the distal end splay
out to maintain secure position of the cannula within
the stoma. Removing the tracheostomy button requires
removing the closure plug fi rst, releasing the tension at
the distal end of the petals. Then the tracheal cannula
can be easily removed.
The Speak EZ tracheal cannula (Figure 8) is another
stoma maintenance device. This tracheal cannula has the
added feature of a built-in speaking valve on the proxi-
mal end. The cannula is made of soft silicone and can be
used for patients who have vocal cord paralysis or sleep
apnea or to maintain the stoma after removal of a tra-
cheostomy tube or T-tube (eg, the Montgomery T-tube).
Both the tracheostomy button and the Speak EZ tra-
cheal cannula may be options for spontaneously breathing
patients who wish to speak but cannot tolerate capping
because of obstruction or resistance to airfl ow. However,

provides a stent for the stoma with no obstruction within

if a patient requires positive pressure ventilation or fre-
quent suctioning, both the tracheostomy button and the
tracheal cannula should be removed and replaced with a
standard tracheostomy tube.
Phonation in Patients Who Require
Intermittent Mechanical Ventilation
When a patient requires intermittent mechanical ven-
tilation, an optimal time to begin phonation attempts is
when the patient is free from mechanical ventilation. One
way to accomplish this freedom is to completely defl ate
the cuff and use fi nger occlusion or a speaking valve for
phonation. Most often, however, a tube change to a TTS
tube is recommended to allow better airfl ow around
the tube. As discussed in a previous article,13 the cuff of
the TTS tube infl ates to seal the airway and allow the
patient to successfully return to mechanical ventilation,
but when defl ated, the cuff essentially disappears.8 With
the cuff defl ated, the TTS tracheostomy tube can also
be safely capped, allowing air to pass through the vocal
cords, producing speech. An added benefi t is that when
the tube is capped, the natural function of the glottis is
restored, and this return to natural function may allow
patients to remain free from mechanical ventilation.8
When a patient is returned to mechanical ventilation,
the cuff of the TTS tracheostomy tube should be infl ated
with sterile water, not physiological saline or air.1,19 Ster-
ile water will distribute pressure evenly and prevent loss of
cuff volume that occurs when the cuff is infl ated with air,
because air diffuses out of the cuff. Also, use of minimal
leak technique is important when the cuff of the TTS tube
is infl ated because the high-pressure cuff will create ele-
vated direct measurements of cuff pressure.8,13,19 Of note,
the TTS tracheostomy tube is a single-cannula tube. If a
patient has large amounts of thick secretions, he or she
may be at risk for obstruction. Therefore, frequent pul-
monary hygiene, with suctioning, methods to mobilize
secretions, proper humidifi cation, and coughing exercises,
are extremely important. These methods include use of a
heated aerosol, positioning the patient sitting up or with
the head of the bed elevated, optimal fl uids to keep secre-
tions thin, and suctioning as needed. If diffi culty insert-
ing a suction catheter or mucus plugging occur with an
TTS tube, changing to a tube with an inner cannula may
be advisable.
Phonation in Patients Who Are
Ventilator Dependent
Restoring speech in patients who are ventilator
dependent can be challenging. Approaches vary accord-
ing to whether or not a patient can tolerate cuff defl a-
tion. Ventilator-dependent patients who can tolerate cuff
defl ation can use leak speech for phonation; those who
cannot protect their airway will require approaches that
maintain cuff infl ation.12 The available devices include
talking tracheostomy tubes, cuffed fenestrated trache-
ostomy tubes, and the Blom tracheostomy tube system.
With all of these methods, manipulation of ventilator
parameters can facilitate speech in a patient who is
ventilator dependent.20

Leak Speech. Leak speech can be an effective aid
in communication for patients who are ventilator depen-
dent; however, it cannot be used in patients who cannot
tolerate cuff defl ation.20 Leak speech is appropriate only
for patients who can tolerate cuff defl ation or have a
cuffl ess tube. To provide leak speech, the cuff is defl ated
and the ventilator settings are adjusted to accommodate
the air leak that results. Tidal volume delivery can be
increased to compensate for the loss of volume during
inspiration through the upper part of the airway.20
Humans naturally speak on exhalation, but leak speech
is the opposite of normal speech: it occurs on inhalation.
The leak during the inspiratory phase allows for phona-
tion, so the patient must be coached to speak on inspira-
tion, as the breath is delivered.19 Leak speech generally
results in short phrases followed by long pauses, so
increasing the inspiratory time on the ventilator can
allow for more syllables per minute.20,21
Some patients have reported anxiety or discomfort
with the use of leak speech because of an unfamiliar
feeling of airfl ow through the upper part of the airway.
These patients can be taught to push down, hold their
breath, or tighten their throat to increase or decrease
the volume delivered to the lungs.22
A respiratory therapist can adjust the positive end-
expiratory pressure (PEEP) to improve the quality of
leak speech and allow phonation during the expiratory
phase.20,23 The exhaled air exits through the ventilator
circuit instead of the upper part of the airway if the PEEP
setting is zero.12 The addition of PEEP can direct exhaled
air to pass through the upper part of the airway so that
the patient can use 60% to 80% of the breathing cycle for
phonation.12 PEEP can also be added to improve voice
quality and comfort.20,23 At the end of a leak speech trial,
and before cuff reinfl ation, additional PEEP should be
turned off to prevent lung hyperinfl ation and related
adverse effects. Obtaining optimal voice quality is usu-
ally a matter of trial and error, so adjustments based on
appropriate evaluations by a health care provider can
limit or obviate interventions that can cause a patient
anxiety or respiratory distress and affect future trials.
Patients frequently become frustrated with this method
of speech, so practice and patience are essential.20
When the cuff is defl ated, supplementing leak speech
with the addition of a speaking valve can be benefi cial in
allowing exhaled air to pass through the upper part of the
airway instead of through the ventilator circuit.12 Figure 9
shows a patient using a Passy-Muir speaking valve within
the ventilator circuit. Egbers et al23 have reported success-
ful phonation with use of bilevel positive airway pressure
and a speaking valve. Some newer ventilator models have
speaking modes that can adjust for the change in airfl ow.8
A speaking valve can improve speech fl ow and volume
in addition to improving voice quality and intelligibility
of speech.20,23 Hoit et al21 reported that the most helpful
adjustment was increasing the inspiratory time.
Patients who use a speaking valve during mechanical
ventilation, like their spontaneously breathing counter-
parts, should be closely monitored. If exhalation is dif-
fi cult with this method, the patient will not be able to
phonate and may not be a good candidate for a speak-
ing valve.9 The valve should be removed immediately if
the patient experiences any breathing discomfort. The
patient should be assessed for evidence of air trapping, an
increased respiratory rate, use of accessory muscles, and
other indications of increased work of breathing.9 The
speaking valve should be removed for suctioning so that
secretions do not occlude the airway during exhalation.9
Talking Tracheostomy Tubes. The most chal-
lenging patients for restoration of speech are those
who are ventilator dependent and who cannot toler-
ate cuff defl ation. In these patients, one method to con-
sider for speech restoration is the talking tracheostomy
tube. A talking tracheostomy tube has an extra port that

the spinal cord in 1996, resulting in complete paralysis at
the level of C1-C2.) Passy-Muir speaking valve is attached
within the ventilator circuit and the cuff is defl ated. Speech
occurs on inspiration as the breath is delivered.

distributes airfl ow above the infl ated cuff (Figure 10).
When this port is attached to an airfl ow source, the air
fl ows through the tubing, and with occlusion of the port,
air is directed toward the vocal cords, thereby producing
phonation. Voice quality is adjusted by increasing air-
fl ow, usually from 5 to 15 L/min for optimal voice qual-
ity; variability depends on the individual patient’s needs.
Signifi cant increases in voice quality are detectable as air-
fl ow increases from 5 L/min to 15 L/min; but even with
this system, voice quality can be a whisper, at best.12,24 The
advantages of this method are that the air used for speech
is completely separate from the air used for breathing and
that it does not require manipulation of the ventilator set-
tings.9 Disadvantages of this method include the need for
the patient or a caregiver to occlude the port for speech;
accumulation of secretions above the cuff, which can clog
the air supply line; poor voice quality; and discomfort and
drying of mucous membranes with high airfl ows.8 Also,
the port might not be properly fi tted in the trachea and
may lead to ineffectiveness of the talking tracheostomy
tube. Patients also need time and practice to perfect the
use of this type of speech.
Cuffed Fenestrated Tracheostomy Tubes.
Another method to restore speech in patients who
require an infl ated cuff is use of a fenestrated trache-
ostomy tube. A fenestration is an opening on the dor-
sal side of the shaft of the tube; it is usually placed
one-third of the distance down the shaft. This opening
allows air to move through the tube and up through
the vocal cords.9 When the cuff on a fenestrated tube
is infl ated, inspiration and expiration occur primar-
ily through
the tube via
the venti-
lator, but a
small amount of air moves through the upper part of
the airway and past the vocal cords via the fenestra-
tion (Figure 11). As with leak speech, ventilator alarms
and settings must be adjusted to accommodate for the
exhaled volume lost through the upper part of
the airway.
An important consideration with the use of a fenes-
trated tracheostomy tube is that the fenestration must
fi t perfectly in the center of the trachea so that it does
not come in contact with the tracheal wall. Block-
age of the fenestration affects breathing, and granula-
tion tissue may form at the fenestration site, causing an
occlusion of the aperture and trauma on removal of the
tube. Because an off-the-shelf fenestrated tube might
not fi t properly, fenestrated tubes may require a custom
order. The anterior and posterior tracheal depths must
be measured and compared with the position of the fen-
estration. If these measurements do not match, a cus-
tom tube should be ordered.8,25 A simple assessment of
proper fi t can be done by removing the inner cannula

tomy tube. Note that when the air port is occluded, air

and shining a light into the tube to observe for an open
versus a blocked fenestration.8,9 Proper placement of
the tube can also be ensured by using bronchoscopy.9 A
blockage of the fenestration affects breathing, and gran-
ulation tissue may form at the fenestration site, causing
occlusion of the aperture and trauma on removal of the
tube. Nurses should also be mindful that secretions can
occlude the fenestration and cause complications as well
as impede optimal phonation.
For the fenestrated tube to work properly, the fenes-
trated inner cannula should be in place when the patient
is attempting to phonate. This fenestrated inner cannula
is usually identifi ed in some way. For example, the 15-mm
connector of the fenestrated inner cannula of the Shiley
tracheostomy tube is colored green. However, if a patient
with a fenestrated tube requires suctioning, the nonfenes-
trated inner cannula must be used so that the suction
catheter does not get lodged within the fenestration.8
Blom Tracheostomy Tube System. The Blom tra-
cheostomy tube system (Figure 12) was designed for
ventilator-dependent patients with no cognitive impair-
ment who require continuous cuff infl ation and who
desire to speak. The system is a relatively new device
that has a fenestrated outer cannula lying just above the
cuff; the position is intended to prevent contact with the
tracheal mucosa. A total of 4 different types of inner can-
nulas can be used with the Blom tube: a standard inner
cannula, an inner cannula with a subglottic suctioning
port, a speech cannula, and a low-profi le inner cannula
that can be used for patients who do not require ventila-
tor support or who can tolerate cuff defl ation. These can-
nulas have a unique locking mechanism that can be used
only with the Blom tube system.26 When phonation is
desired with a Blom tube for a patient receiving mechan-
ical ventilation, the uniquely designed speech cannula
should be used. This cannula has 2 valves on its soft and
fl exible shaft. On inhalation, air is delivered to the lungs
through a fl ap valve that opens at the tip of the tube
(Figure 13). Upon exhalation, the fl ap valve closes, and
air passes through the fenestration and through a bub-
ble valve along the shaft of the speech cannula. Before
the speech cannula is inserted, the patient should be
assessed to ensure that he or she is breathing comfort-
ably and that the airway is clear of secretions. After the
speech cannula is placed, airfl ow through the upper part
of the airway should be assessed. If the patient has any
indications of respiratory distress, the speech cannula
should be immediately removed and replaced with the
standard cannula.26 Patients with thick or copious secre-
tions should not use this type of tube.26
Another unique feature of the Blom system is the
exhaled volume reservoir. This small bellows system
expands and traps air during the inspiratory phase and
then returns that air to the ventilator during the expi-
ratory phase so that the air can be measured as exhaled
volume.26,27 This reservoir should be used only while the
speech cannula is in place; it should be removed when
the speech cannula is not in use.26,27
Conclusion
Many different methods can be used to restore pho-
nation in patients who have a tracheostomy, and criti-
cal care nurses are the ideal members of the health care
team to facilitate a planned and systematic approach to
achieving phonation. Coordination of the interdisciplin-
ary team, which includes critical care nurses, respira-
tory therapists, speech pathologists, advanced practice
nurses, and physicians, is essential to the goal of voice
restoration. Early involvement of this team can improve
clinical outcomes and patient satisfaction by reducing
the time needed for phonation.28
Nurses who provide care for patients with tracheos-
tomies need not only focus on the tasks associated with
care but also acknowledge that patients with trache-
ostomies can struggle with loss of the voice. The team
must be sensitive to this loss and explore the anger and
frustration that can overwhelm patients.5 Nurses can

facilitate a method of communication that is ideal for
the patient and can be consistent in its implementation
until the patient’s voice is restored.5 Patients need a
way to communicate their feelings as well as their phys-
ical and emotional needs, and in turn, they are grateful
to nurses who take the time to be patient, who are cre-
ative with methods of communication, and who pro-
vide reliable quality care.4 CCN

1. Which of the following are indications for tracheostomy placement?
a. Confirmed ventilator-associated pneumonia
b. Prolonged intubation with unsuccessful weaning
c. Prolonged need for vasoactive medications
d. Two or more self-extubations
2. Which of the following statements best describes the difference between capping
a tracheostomy and using a speaking valve?
a. For a cuffless tube, a speaking valve should not be used and only a cap is appropriate.
b. Capping a tracheostomy should never be done on a fenestrated tube while a speak-
ing valve can be used on any tube.
c. A speaking valve will allow air to enter into the tracheostomy tube while capping
will not.
d. There is no difference between capping a tube and using a speaking valve.
3. Which of the following devices should be used to provide supplemental oxygen
for a patient with a speaking valve?
a. Nasal cannula
b. High-flow nasal cannula
c. Venturi mask
d. Humidified tracheostomy collar
4. Which of the following statements do the authors suggest as rationale for avoid-
ing the use of a speaking valve on an inflated cuffed tube?
a. The cuffed tube will not allow for air to escape during exhalation, which could lead
to barotrauma.
b. The rate of inhalation of air through the speaking valve may damage the cuff.
c. The speaking valve can prevent the expectoration of mucus when the cuff is inflated.
d. The cuffed tube may prevent adequate inhalation of supplemental oxygen through
the speaking valve.
5. Which of the following do the authors suggest as contraindications for the use of
a speaking valve?
a. Previous failed attempt at using a speaking valve
b. Total laryngectomy
c. Supplemental oxygen requirements
d. Acute delirium
6. Advantages to using the tracheostomy button and the Speak EZ tracheal cannula
include which of the following?
a. Having the ability to custom fit the tracheostomy ties
b. Reducing the need for mechanical ventilation
c. Eliminating the bulk of the tube in the air way
d. Decreasing the supplemental oxygen requirement
7. Leak speech is most appropriate for which of the following patients?
a. Those who no longer require mechanical ventilation
b. Those who require mechanical ventilation at night
c. Those who can tolerate cuff deflation without signs of distress
d. Those who have thick secretions that can be expelled easily
8. Which of the following adjustments to a mechanical ventilator can improve leak
speech quality?
a. Decreasing tidal volume c. Decreasing inspiratory time
b. Increasing positive end-expiratory pressure d. Increasing oxygen
9. Which of the following statements describes the differences between normal speech
and leak speech?
a. Normal speech often is comprised of short phrases whereas leak speech generally
has long phrases with pauses.
b. here is no difference in quality between normal speech and leak speech.
c. The use of leak speech often requires supplemental oxygen while the oxygen demands do
not increase with normal speech.
d. Leak speech occurs during inhalation while normal speech occurs during exhalation.
10. The role of critical care nurses in restoring phonation in patients with
a tracheostomy includes which of the following?
a. Deferring the decisions regarding devices to a speech therapist
b. Monitoring for complications of respiratory distress exclusively
c. Reporting patient frustrations of inability to communicate to the health care provider
d. Serving as a member of the interdisciplinary health care team to assist in the coordination
of care
11. Proper steps involved in cuff deflation include which of the following?
a. Prior coaching and prepping of the patient, deep oropharyngeal suctioning, cuff
deflation, observe for symptoms of respiratory distress
b. Ask patient to take deep breath, cuff deflation, deep subglottic suctioning, increase
fraction of inspired oxygen
c. Slow cuff deflation over several minutes, increase fraction of inspired oxygen, reassure
patient, deep oropharyngeal suctioning
d. Deep subglottic suctioning, cuff deflation, ask patient to take a deep breath, observe
for respiratory distress
12. Considerations for safe capping of a tracheostomy tube include which of the
following?
a. Use of a standard cuffed tube with the cuff deflated
b. Use of a cuffless, tight-to-shaft, or fenestrated tube of appropriate size
c. Use of a Speak EZ tracheal cannula
d. Use of humidified tracheostomy collar
