NURSING ANM AND GNM

Detailed explanation-1: -IPAP may decrease the work of breathing by supplementing inspiratory airway pressure and decreasing inspiratory muscle work. EPAP may counteract the inspiratory threshold imposed by auto-PEEP and increase intraluminal pressure, which ‘pneumatically’ holds the airway open, thus preventing dynamic airway collapse.

Detailed explanation-2: -BiPAP provides a higher pressure during inhalation and lower pressure during exhalation. Pressures generally range from EPAP minimum of four to IPAP maximum of 25–30.
