ABSTRACT:
A resuscitator inhalator device for the administration of oxygen or mixtures of oxygen and air to a striken person is disclosed. The device consists of a body connected to a supply of oxygen under pressure. The body has a manually operated valve permitting flow of oxygen under pressure through the body to the person and which permits continuous flow of oxygen or for manually operated intermittent flow. A metered orifice is provided within the body for metering a maximum pressure of oxygen which can pass therethrough to a patient. A supplementary metering arrangement is selectively adjustable to permit increased pressure flow of oxygen to the patient, the highest possible pressure of oxygen which can pass through the device to the patient being not greater than the highest safe pressure for a healthy lung. An adjustment ring on the body permits the device to administer pure oxygen or a mixture of oxygen and air.
