ABSTRACT:
A portable resuscitation apparatus is described including a flat support having a neck cushion at one end thereof to properly position the patient's head and to also provide a secure means for attaching a mask to the patient's face and head. The mask includes a pair of cheek straps extending therefrom which are secured to opposite sides of the neck cushion. A flexible strap is secured to the upper central portion of the mask and to the neck cushion. A flexible hose extends from the mask to a ventilation pump mounted on the support whereby compression of the pump will cause air to be forced through the flexible hose to the mask. The mask includes a first valve provided therein which permits communication from the atmosphere of the interior of the mask during the times that the pump is not being operated. The mask also includes a second valve which is vented to the atmosphere upon a predetermined pressure being reached within the mask. A source of oxygen is in communication with the flexible hose so that the ventilation pump will supply pure oxygen to the patient during the initial portion of the ventilating action. An electronic rhythm unit is mounted on the support for indicating the prescribed beat for proper closed chest massage and ventilation.
