Low-flow Anesthesia Series: Dilution Effect of Rebreathing

In this educational video you will learn how the dilution effect of rebreathing affects the measured oxygen and anesthetics agent values displayed on an anesthesia machine that uses a circle breathing system. This video explains why set oxygen and agent values may not match measured values when the patient is rebreathing recycled gas, which is the result of mixing fresh gas with recycled gases when using low fresh gas flows.
