  1. aPulsatile flow is patient pulsatile flow, measured at systolic blood pressure of 110–130 mmHg and diastolic blood pressure of 60–80 mmHg
  2. bNon-pulsatile flow is pump non-pulsatile flow, measured during cardiopulmonary bypass at maintained mean arterial pressure of 70 mmHg and pump flow of 3.0-3.5 L/min/m2
