Webe.g. PEEP will cause less increase in intrathoracic pressure if lungs are poorly compliant (e.g. severe ARDS) e.g. regional overdistention is more likely with focal lung diseases (e.g. lobar pneumonia) Not all ARDS patients are “PEEP responsive” and the degree of lung recruitability in “responders” is variable (Gattinoni et al, 2024) WebTransthoracic pressure is negative at residual volume and at FRC, meaning the chest wall is smaller than its unstressed volume and its tendency is to spring out.
