Abstract
Breathing equipment, for instance a resuscitator, adapted to supply ambient air or alternatively oxygen from a pressurized source, the equipment including non-rebreathing valve mechanism having inspiration and expiration ports, and arranged to assure automatic operation to effect oxygen 'blow-by' under conditions of operation tending to close the expiration port, and thereby prevent undesirable build-up of pressure in the patient's lungs.
