cardiac chamber de-airing. Chronic rheumatic heart diseases
Conditions
Interventions
Intervention 1: After turning the ventilator off, the flow of oxygen flow was maintained at the rate of 0.5L/min and the APL valve was placed in “Man” position on 20 mbar (20 hectopascal, 15mmHg). Int
Prevention
After turning the ventilator off, the flow of oxygen flow was maintained at the rate of 0.5L/min and the APL valve was placed in “Man” position on 20 mbar (20 hectopascal, 15mmHg).
During the surgery and CPB, the ventilator (Drager, Fabius) was turned off and the flow of fresh air was totally ceased and adjustable pressure limit (APL) valve was placed in “Spont” position.
