Re-Adjustment of Sweep Gas Flow to the During the Rewarming Period of the Cardiopulmonary Bypass
Recruiting
- Conditions
- Optimal Sweep Gas FlowDetermination 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.
