Factors influencing delivered mean airway pressure during nasal CPAP with the RAM cannula

摘要

ObjectiveTo measure mean airway pressure (MAP) delivered through the RAM Cannula (R) when used with a ventilator in CPAP mode as a function of percent nares occlusion in a simulated nasal interface/test lung model and to compare the results to MAPs using a nasal continuous positive airway pressure (NCPAP) interface with nares fully occluded.
