Reported Complications of Bubble Continuous Positive Airway Pressure Systems in Low-Resource Settings: An International Survey

Lower respiratory tract infections (LRTIs) are the leading cause of death in young children globally. Most of the global burden of mortality from LRTIs occurs in low-resource settings (LRSs), where obtaining and maintaining respiratory support devices such as commercial bubble continuous positive airway pressure (bCPAP) can be prohibitive. Low-cost bCPAP devices exist, such as the homemade WHO-style bCPAP design, but the safety of this design has been called into question. Based on our team's experience with homemade bCPAP, the side effects of the high pressures described in recent studies are not commonly encountered. Therefore, we sought feedback via an international survey about various complications including pneumothorax from practitioners in LRSs who use two forms of homemade bCPAP. In our qualitative survey, we did not find a convincing pattern in the recall of complications between commercial bCPAP and homemade bCPAP with narrow- or wide-bore expiratory limb in neonates or older children.
