Your patient is presenting for coronary artery bypass grafting. Post-induction hemodynamics include: BP 120/80, HR 78, SVR 1200 dynes/sec, cardiac output 5 L/min, SpO2 96%.  ABG: pH = 7.34, PaCO2 = 32, PaO2 = 102, HCO3- = 22, BE +0.  Hgb 9.1, Hct 27. Calculate this patient’s DO2 (arterial oxygen delivery). [Use 1.39 in CaO2 equation for oxygen combining capacity].
