Cardiopulmonary bypass (CPB) is a common method used to minimize bleeding during surgery 1 and could reduce neurological morbidity rates. 2 However, this procedure carries a high risk of brain injury and is frequently associated with postoperative lesions. 3,4 Pulmonary edema is the central link for acute lung injury (ALI) after CPB, 5 …

WebNov 21, 2024 · Rationale for circulatory arrest is surgical access. The surgical approach to the replacement or repair of the aortic arch and aortic root requires that at some stage the aorta be incised and open to air. To have blood flowing through it at this stage would be fairly uncivilised- impractically bloody and embolism-prone. Cardiopulmonary bypass machines allow blood circulation and cooling to continue below the temperature at which the heart stops working. By cooling blood directly, cardiopulmonary bypass also cools people faster than surface cooling, even if the heart is not functioning.
