  1. Data presented as median (25th to 75th interquartile range). FiO2, fraction of inspired oxygen; MAP, mean arterial pressure; MV, minute volume; VT, tidal volume; PaCO2, partial pressure of arterial carbon dioxide; PaO2, partial pressure of arterial oxygen; PECLA, pumpless extracorporeal lung assist; vv-ECMO, veno-venous extracorporeal membrane oxygenation.
