Pressure–volume (PV) loop in each group. The black line represents the baseline PV loop (pre), and the red line represents the PV loop at the end of the experiment. (post). (A) PV loop in Group 1. While EDV, ESP, SV, SW, Ees (slope of ESPVR), and PVA increased significantly, the EDP (each point of EDPVR) showed a significant decline after 2 h of ECMO. (B) PV loop in Group 2. A significant increase in EDV, ESV, ESP SW and PVA was seen after 2 h of ECMO. (C) PV loop in Group 3 (healthy control group). No significant changes in PV derived parameters. (D) PV loop in Group 4 (septic control group). EDP, Ea, PVA decreased significantly.
