Resumen de Continuous Positive Airway Pressure: To Bubble or Not to Bubble?
Continuous positive airway pressure (CPAP) systems can be broadly grouped into continuous flow or variable flow devices. Bubble CPAP (bCPAP) is a continuous flow device and has physiologic properties that could facilitate gas exchange. Its efficacy has been reported to be similar to variable flow CPAP systems when used as a primary mode of respiratory support. Post-extubation bCPAP is reported to significantly reduce extubation failure rates among preterm infants ventilated for less than 2 week when compared to Infant flow driver CPAP (variable flow). bCPAP has been successfully used in resource-poor settings. The success of CPAP is, however, dependant on good nursing care and clear management protocols for weaning and escalation of care.
