Abstract
Abstract A breathing aid for use in expired air resuscitation is described. It includes a conduit into which the rescuer blows at 15 and which is inserted into the patients mouth or nostril(s) at 3 and 4. A non-return valve protects the rescuer from infection from the patient. The non-return valve may be combined with an exhaust port 21 for exhausting air from the patient to atmosphere, or a separate exhaust port may be provided. <IMAGE>
