Hemodynamic and Metabolic Response After Cardiopulmonary Bypass: Continuous Monitoring of CO2 Production
The increase in metabolic rate after cardiopulmonary bypass (CPBP) represents a critical factor in patients with reduced oxygen availability due to hypovolemia or unstable cardiac function [1, 2]. Raison et al.  demonstrated an increased oxygen consumption (V̇O2) in postoperative open heart surgery patients. The effects of oxygen debt repayment, mechanical ventilation, and shivering were proposed as possible explanations for changes in metabolic rate [3, 4]. Rodriguez et al.  observed an increase in energy requirements in patients after major surgical procedures complicated by intraoperative hypothermia.
