Fig. 1From: Airway opening pressure in an obese ARDS patient: just the start of airway recruitmentLeft panel: Respiratory system static pressure–volume loop by slow inflation-deflation with pressure ramps of 2 cmH2O/s. The arrow indicates the airway opening pressure (AOP). Right panel: Airway pressure (Paw), esophageal pressure (Pes), airflow, volume change and capnography during PEEP steps from 16 down to 5 cmH2O and backBack to article page
