pH-stat blood gas management
Blood gas management strategy that maintains pH at 7.40 and PaCO2 at 40 mmHg when corrected to patient's actual temperature during hypothermic cardiopulmonary bypass.
Full Definition
A blood gas management approach used during hypothermic cardiopulmonary bypass where arterial blood gases are temperature-corrected to maintain pH at 7.40 and PaCO2 at 40 mmHg at the patient's actual body temperature. This strategy contrasts with alpha-stat management and may provide better cerebral perfusion during deep hypothermia. The choice between pH-stat and alpha-stat management can significantly impact neurological outcomes, particularly in pediatric cardiac surgery.
Usage
Usage note: Always hyphenate when used as a compound modifier.
