Re-Adjustment of Sweep Gas Flow to the During the Rewarming Period of the Cardiopulmonary Bypass

Recruiting
Conditions
Optimal Sweep Gas Flow
Determination of Optimal Sweep Gas Flow for Different Phases of Cardiopulmonary Bypass
Interventions
Other: Gas Flow Adjustment
Registration Number
NCT06013189
Lead Sponsor
Acıbadem Atunizade Hospital
Brief Summary

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.
