Q

CPAP vs BiPAP Differences

A

CPAP:
Increases PRESSURE IN lungs, opens collapsed alveoli

PUSHES O2 across alveolar membrane, and forces interstitial fluid back into the pulmonary circulation

BiPAP:
Two Pressures (Ins iPAP/ Exp ePAP)
iPAP higher pressure for bases
ePAP lower pressure to keep bases open
