Summary

Low-flow anesthesia (LFA) is a technique in which at least 50% of the exhaled air, after carbon dioxide absorption, is mixed with a certain amount of fresh gas and returned to the patient during the next inspiration. In 1974, R. Virtue defined minimal flow anesthesia (MFA) as 0.5 L/min. In 1984, Baker and Simionescu classified LFA as 0.5-1 L/min and MFA as 0.25-0.5 L/min. The aim of this study is to investigate whether there are hemodynamic differences between open-heart surgery cases performed with LFA at different fresh gas flow rates.
