The ACT is monitored every 20–30 minutes during bypass to ensure that adequate anticoagulation is maintained. Required ﬂow rates for cardiopulmonary bypass depend on the patient’s body surface area and temperature. 2 L/m2 per minute is required for adequate perfusion. Oxygen consumption is reduced, however, by 50 per cent for every 10°C drop in temperature. At 20°C, a 30-minute period of circulatory arrest can be safely tolerated. A guide to the adequacy of tissue perfusion can be achieved by measurement of the mixed venous oxygen saturation.
Accordingly, additional intravenous agents are typically administered at these times. 40 Cardiopulmonary bypass: access and technical options OPERATION Incision and access 2a In the majority of operations that require cardiopulmonary bypass, access is via the median sternotomy.
