Circle circuit<br />

<strong>The</strong> circle circuit is a breathing circuit which allows rebreathing of expired gases. It allows a<br />

more economical use of gases and volatile anesthetic agents. A circle circuit requires the use<br />

of a CO2 absorber to prevent hypercarbia.<br />

A circle system is shaped as a circle rather than a straight line. It has two one way valves<br />

(one inspiratory and one expiratory) to ensure proper direction of flow.<br />
