S: start of surgery for extracorporeal cardiopulmonary support. T: tracheal intubation. Arterial blood gas data were measured at A1, A2, and A3. A1: pH, 7.46; PaCO₂, 36.8 mmHg; PaO₂, 240 mmHg; base excess, 2.4 mmol/L; and SaO₂, 100%. A2: pH, 7.39; PaCO₂, 46.8 mmHg; PaO₂, 118 mmHg; base excess, 2.8 mmol/L; and SaO₂, 99%. A3: pH, 7.49; PaCO₂, 33.3 mmHg; PaO₂, 509 mmHg; base excess, 2.9 mmol/L; and SaO₂, 100%.
