From: Should we continue searching for the single best PEEP?
PEEP titration using constant inspiratory pressure of 14 cmH2O during pressure-controlled ventilation (PCV) in two different passive severe COVID-19 ARDS patients. Colored boxes are pointing out similar lung mechanics at different PEEP levels. Vte—expiratory tidal volume, CRS—respiratory system compliance, Vd/Vt—dead space fraction, VA—alveolar ventilation, PEEP—positive end-expiratory pressure
