Feasibility and Acceptability Followed by Effectiveness of bCPAP for Treatment of Bangladeshi Children With Severe Pneumonia

"In Bubble CPAP, pressurized oxygen from an oxygen cylinder is delivered to the nasopharynx of the baby. An underwater tube (expiratory arm) that acts as a blow off valve is interposed between the oxygen source and the baby. Adjusting the height of the water column above the exit of the tube can regulate the pressure in the system and the amount of CPAP delivered to the baby. The constant bubbling of gas through the blow off mechanism delivers the bubbling CPAP effect. Oxygen may be delivered by nasal prongs inserted into the nostril of child.~The system has three components:~1. Continuous gas flow into the circuit: The gas flow rate required to generate CPAP is usually 5-10 L/min.~2. A nasal interface connecting the child's airway with the circuit:~3. An expiratory arm with the distal end submerged in water to generate end-expiratory pressure.~The source of oxygen will be either an oxygen concentrator or cylinder, central distribution through pipelines."
