Expired air resuscitation has been evaluated in 16 anesthetized curarized human subjects. A mask resuscitator suitable for use in contaminated atmospheres was employed. The parameters measured include the alveolar carbon dioxide and oxygen concentrations of the operator and of the subject, the air flow and tidal volume, the subject's oxygenation by ear oximeter and the subject's arterial oxygen saturation, carbon dioxide tension and ph. All parameters independently indicated the complete adequacy of the method under widely varying conditions of rate and volume of inflations and with multiple operators. Alveolar oxygen concentrations in the subject during prolonged performance of the method were sustained above the normal range.
