Official title
Re-Adjustment of Sweep Gas Flow to the During the Rewarming Period of the Cardiopulmonary Bypass to Prevent Alkalosis
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.
Interventions
- Other Gas Flow Adjustment
Decreased gas flow causes PaCO2 to elevate and prevents alkalosis
Primary outcome measures
- Arterial pH lever lower than 7.30 [Time frame: during the cardiopulmonary bypass and postoperative 24th hour]
Secondary outcome measures (1)
- rSO2 20% below initial value [Time frame: during the cardiopulmonary bypass]
Eligibility criteria
Inclusion criteria
- Patients over 18 years of age
- Elective CPB surgery
Exclusion criteria
- Patients undergoing minimally invasive surgery
- Patients undergoing robotic cardiac surgery,
- Patients undergoing deep hypothermia,
- Patients undergoing total circulatory arrest,
- Patients whose FiO2 requirement is high that cannot be applied to target gas flow
