Effects of prone position on ventilation–perfusion matching in a representative study patient. Left: performed in the supine (T0), Middle: 3 h after PP initiation (T1), Right: at the end of PP (T2). During prone ventilation, pulmonary blood flow is mostly unmodified at the early stage and then gradually changes over time. Long prone ventilation increases dorsal ventilation and perfusion, which results in improved ventilation–perfusion matching
