Introduction
Cardiac arrests and accidents are the most common
emergencies with grave consequences but the high mortality
associated with them can be easily prevented most of the
times by some very simple maneuvers and skills. Cardiac or
respiratory arrests are a very common emergency in not just
the adult group but also in the neonatal period. These
emergencies can be easily managed by knowledge and
practice of resuscitation skills. Resuscitation "is the art of
restoring life or consciousness of one apparently dead."1
Resuscitation attempts date way back in time. Early records
from Egyptian mythology and the Bible suggest that mouth-
to-mouth and mouth-to-nose respiration were among the
earliest resuscitative efforts using artificial respiration.2,3
The technique has also been used for many centuries by
midwives in attempts to revive apparently stillborn infants.4
One of the first authenticated cases of recovery following
artificial respiration using the mouth-to-mouth technique
was the resuscitation of a suffocated miner by Tossach in
1744.5Over time, resuscitation skills have evolved into a
proper protocol, which involves cardiopulmonary
resuscitation (CPR) commonly known as Basic Life
Support (BLS). However BLS involves techniques other
than CPR as well but these two are used interchangeably.
Invented in 1960, CPR is a simple but effective
procedure that allows almost anyone to sustain life in the
early critical minutes after cardiac and respiratory arrest.
Since atherosclerotic heart disease is the overall leading
cause of death and trauma is the leading cause of death
among those aged 1-44 years it is crucial that such efforts be
circumstances? Major work rests with the government and
policy makers but the role to be played by health professionals
cannot be ignored. Health education can be a powerful tool with
continued campaign for betterment of the life of people. Is there
any other way to address this issue?

Abstract
Objectives: To study the awareness on Basic Life Support (BLS) (CPR) in undergraduate medical students.
Methods: Across sectional study was conducted by using responses to a questionnaire regarding BLS by 61
students. The results were analyzed with SPSS version 11.101.
Results: Out of 61 students only 9 (14.7%) had taken a BLS (CPR) course while 52 (85.3%) students had not
attended any such course. Significantly more number of students had the theoretical knowledge about BLS
(76.07% vs 49.18%, p<0.00). Practical knowledge about BLS was scored as having no, some and complete
knowledge of the course. Of all the students, 57.3% had no knowledge, among those 34% had heard BLS from
somewhere, 22.9% had some knowledge out of which 50% had heard about it. Significantly less number of
students had complete knowledge about BLS (4% p<0.05). Among the students who had taken the course, 22%
had complete knowledge (p<0.05). Significantly less number of students knew about the skills for BLS (21%
p<0.05).
Conclusion: Most of the medical students although had not attended the course, still they had some knowledge
about BLS. Inclusion of this course in the undergraduate curriculum will increase awareness and application of
this valuable life saving maneuver (JPMA 59:57; 2009).
maintained.6Cardiac arrest results in the cessation of blood
supply to the brain leading to depression of breathing as
well. Thus this combination of no breathing and circulation
causes generalized ischaemia, which in cases of brain
allows a narrow window of ten minutes only. That is if
anything has to be done it has to be done within ten minutes
because after that survival is impossible. This awareness has
placed a growing demand on physicians for expertise in
resuscitation.7
Basic Life Support [BLS] includes both prompt
recognition and immediate support of ventilation and
circulation in case of respiratory or cardiac arrest.8It has a
combination of skills including mouth-to-mouth breathing
to support ventilation and chest compression to normalize
blood circulation to the brain and vital organs. Knowledge
of BLS and practice of simple CPR techniques ensures the
survival of the patient long enough till experienced medical
help arrives and in most cases is itself sufficient for
survival.9
BLS requires nothing as far as resources are
concerned and its importance is undeniable. Proper practice
of the techniques and maneuvers enables a person to
effectively resuscitate a victim. Ideally everyone should
know BLS and CPR but its awareness to medical personnel
should be a pre-requisite for entering into this field. Newly
qualified doctors are expected to take part in resuscitation
from their first day.9In Pakistan very little data is present
which addresses the awareness of the medical personnels
including students, doctors and paramedical staff regarding
this highly effective and easy maneuver. Furthermore the
awareness should not only be limited to the medical
personnel but also to the general population. The objective
of this study was to determine the level of awareness
regarding BLS and knowledge of involved skills and its
practical implementation among medical students.
Methods
An anonymous questionnaire regarding (a)
awareness and (b) skills involved in BLS was used to assess
the levels of awareness to BLS, its practical knowledge and
opinion regarding its importance as a part of undergraduate
medical curriculum. The aspects interrogated were about
the abbreviation of BLS, the process and its requirements,
who need to know it and why and under what conditions a
person may require it. The second questionnaire covered the
skills, and the know how of the maneuver. It interrogated
about the assessment of responsiveness, airway, breathing
and circulation in unconscious patients of different age
groups. It also inquired about how to assist in breathing and
giving chest compressions. The second questionnaire had
questions on participation in any BLS course and opinion
regarding inclusion of BLS in the undergraduate Medical
curriculum. It was a cross sectional study conducted in
Jinnah Medical and Dental College during November and
December of 2006. Atotal sample of 86 students was
selected by systematic sampling in which every 5th student
was selected and they were asked to fill up the
aforementioned questionnaires. Analysis of the results was
done using SPSS version 11.0.
Results
Asignificant number of students were aware of the
general idea of BLS which was assessed by the correct
responses. Alarge number of students knew about the
abbreviation, purpose and importance of the maneuver
(first, second and last question) (p<0.001) (Table). Only
10.9% students replied incorrectly (p<0.001).
On the contrary, a big number of students responded
incorrectly to the questions on the skills involved in BLS
(CPR). On an average only 18%, (p<0.001) provided
correct answers. Of all 36.66% students did not know about
BLS and the rest gave wrong answers.
Figure depicts the graphical representation of the
student's idea about the importance of learning basic life
support course and its inclusion in the undergraduate
curriculum. It shows that about half of the students had
heard about the BLS course. The figure shows that
significantly more number of students had never attended

Discussion
The results of the study showed that medical
students in the aforementioned sample lagged behind in
cognitive awareness of BLS though they were aware of the
importance of the skills and considered it important to be a
part of the curriculum. Awareness of BLS was present in
66.6% students, but skills were found in 18% only. Our
study emphasized on the cognitive approach to general
perception and skills of BLS. Practical application is
difficult to assess through a questionnaire as cognitive
abilities are superior to technical skills.
Alarge number of study participants (79%) were of
the opinion that training of Basic Life Support should be a
part of the undergraduate curriculum. It is also a fact that
after graduation training of resuscitation skills is difficult.
Busy residency schedules and lack of resources act as
barriers. Doctors still are expected to learn resuscitation
skills in the clinical setting, where there is little opportunity
to correct poor techniques.9Given this situation, and the
fact that many junior doctors are not competent in carrying
out effective cardiopulmonary resuscitation,10,11perhaps
training in advanced life support should become a
standardized and mandatory component of all medical
school undergraduate curriculums.9
Besides BLS there are six other resuscitation courses
along with BLS which also need to be taught at an
undergraduate level. These are courses in first aid, basic
trauma life support (BTLS) and advanced cardiac, trauma,
paediatric and neurologic life support (ACLS, ATLS, PALS
and ANLS). These courses can be integrated in the
curriculum and taught over the period of medical education
years which will ensure doctors with effective resuscitation
skills by the end of graduation. The BLS course done can go
on to ACLS and other advanced courses. On successful
completion of the BTLS and ATLS courses the student will
be able to use the basic and advanced life support skills
essential in resuscitating the traumatized patient.12 Also
resuscitation skills need to be refreshed after some time, and
short courses can be offered to personnel who already have
taken a course previously to spare the funding and assure
effective revision. As found by Cooper et al there was
significant improvement in the knowledge and skills of
people who have taken BLS course six months ago after
taking a short ILS(Immediate Life Support) course.13
From our study we conclude that lack of awareness
regarding BLS among medical students is a serious issue
that needs to be addressed promptly. BLS and other
resuscitation skills should be a part of the undergraduate
curriculum and students should master the skills during
their studies. More research is warranted in our set up also
involving other medical personnel and to determine an
appropriate and efficient course design.
