About this trial

The investigators designed this prospective observational study with the theory that alkalosis caused by decreased CO2 solubility due to temperature increase during the rewarming period of the Cardiopulmonary Bypass could be prevented by reducing the sweep gas flow during the rewarming period.

Treatments tested in this trial

Gas Flow Adjustment
Other intervention
Decreased gas flow causes PaCO2 to elevate and prevents alkalosis
