Results from recent large randomized trials investigating the use of high PEEP in patients without ARDS all suggest that high levels may increase mortality due to hypotension and bradycardia. A careful assessment of cardiac function — with particular focus on the right ventricle — should be performed before planning our ventilation strategy in any setting, including COVID-19 and ARDS in general. Mechanical ventilation should be respectful in regards of heart function, and tolerant with moderate hypoxia and hypercapnia, noninvasive (whenever possible) and synchronized.
