Objective
Continuous Positive Airway Pressure (CPAP) is recommended in the treatment of respiratory distress syndrome of premature newborns, however there are significant barriers to its implementation in low resource settings. The objective of this study was to evaluate the feasibility of use and integration of Vayu bCPAP Systems into the newborn...

... to make high quality CPAP available for global access.(17) Vayu bCPAP Systems have been used for three years to treat neonates with RDS, pneumonia, COVID-19, and other causes of severe respiratory distress in 13 countries. The Vayu bCPAP System revolves around an innovative air/oxygen blender that supplies the circuit with oxygen enriched air. (Fig. 1C). A bacterial/viral filter is positioned downstream of the blender. Enriched, filtered gas passes through a humidifier and enters the inspiratory limb of the breathing circuit. Gases are delivered to the patient by nasal prongs. The expiratory limb of the breathing circuit is attached to a second filter, which connects to the wand of ...

... the inspiratory limb of the breathing circuit. Gases are delivered to the patient by nasal prongs. The expiratory limb of the breathing circuit is attached to a second filter, which connects to the wand of the pressure generator. The wand can be rotated to alter the depth of submersion in the water column and thereby adjust the delivered pressure (Fig. 1A). (17) The Vayu bCPAP .

Context 4
... A concern with the Vayu bCPAP Systems was occasional disconnection of the oxygen tubing from the blender at FiO2s greater than .60. (17) Upon further investigation it was found that oxygen tubing ( Figure 1A) that had been reprocessed many times (distinguishable by exterior hardening/yellowing) became vulnerable to disconnection at higher FiO2s. Hose clamps were introduced as an interim measure to secure older oxygen tubing, and subsequently the material of the oxygen tubing was modified to increase the hardness (from ASTM D 2240 Shore A 70 hardness to 80 hardness). ...
