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

Acıbadem Atunizade Hospital90 enrolled

Overview

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.

Study Type

OBSERVATIONAL

Enrollment

Conditions

Optimal Sweep Gas Flow Determination of Optimal Sweep Gas Flow for Different Phases of Cardiopulmonary Bypass

Interventions

Gas Flow AdjustmentOTHER

Decreased gas flow causes PaCO2 to elevate and prevents alkalosis

Eligibility
