Functional residual capacity<br />

Functional residual capacity (FRC) is the volume of air left in the lungs at the end of exhalation<br />

during quiet respiration. It represents a balance between two opposing forces: elastic recoil<br />

of the lung and the tendency of the ribcage to spring outwards.<br />

FRC is reduced in pregnant patients, pediatric patients and those patients who are obese. A<br />

reduced FRC can lead to rapid desaturation on induction of anesthesia. Careful preoxygenation<br />

is even more important in these patients. (Access glossary index for diagram)<br />
