Does analysis of gas from the exhaust port of a membrane oxygenator accurately estimate anesthetic tension in arterial blood in patients undergoing hypothermic cardiopulmonary bypass?
Anesthetic tensions in arterial blood can be accurately monitored by analyzing the gas emerging from the exhaust port of a membrane oxygenator during cardiopulmonary bypass.
LOCKWOOD et al. (1999) conducted an observational in Hypothermic cardiopulmonary bypass (n=67). Oxygenator exhaust gas analysis vs. Arterial blood analysis was evaluated on Anaesthetic tension agreement between oxygenator exhaust gas and arterial blood. Oxygenator exhaust gas analysis accurately estimated arterial blood anaesthetic tension (95% limits of agreement: -0.08% to 0.09% for isoflurane, -0.65% to 0.58% for desflurane).
