Air trapping (auto-PEEP) = gas trapped in alveoli at end-expiration. Suspect auto-PEEP if P(plat) >30 cm H2O, or if hypotension develops. First step is to disconnect vent and allow trapped air to escape. Prevent further air trapping by decreasing RR and increasing expiratory time #Pathophys #PCC #AutoPEEP #AirTrapping #ALiEM
