Abstract

A continuously positive-pressure respiratory aid, providing positive-pressure inhalation and exhalation of a patient suffering from apnea or other respiratory disorder in which forced breathing-assistance is to be administered. A source of pressurized air, an outlet to a face mask, and a vent outlet all are in parallel communication; and the vent is controlled by a spring-pressed valve body which is adjustable to control the above-atmospheric pressure to individual patient's needs. A safety feature provides that the valve body is sufficiently in vent position for the patient's exhalation even if the valve body is somehow blocked from its normal vent movement; and a viscous grease in the support of the valve body prevents objectionable resonant chatter.
