  1. aECMO, Extracorporeal membrane oxygenation; FiO2, Fraction of inspired oxygen; HFOV, High-frequency oscillatory ventilation; PA/C, Pressure assist/control; PaCO2, Partial pressure of carbon dioxide; PaO2, Partial pressure of oxygen; Paw, Airway pressure; PEEP, Positive end-expiratory pressure; Pi, Initial pressure; PS, Sustained pressure; PSV, Pressure support ventilation; SIMV, Synchronized intermittent mechanical ventilation; SpO2, Peripheral capillary oxygen saturation; rpm, rounds per minute. The two liters per minute means the range of blood flow provided at the pump rounds level of ECMO.
