Abstract

Oxygen saturation was measured by pulse oximetry in 33 psychiatric patients breathing air during recovery from 60 episodes of electroconvulsive therapy. Desaturation to less than 90% occurred in 17% of patients. Oxygen saturation values in recovery were significantly lower than pre-operative saturations (p = 0.0014 using ANOVA), with a significant difference (p = 0.001) for up to 5 min in recovery.
