Abstract
An anesthetist's device for inducing constant positive pressure within the airway passages of a patient, adaptable for use with a mouthpiece, a mask, or in conjunction with an endotracheal tube. Said device comprises a hollow, cylindrical channel serving as a conduit for gases either spontaneously or mechanically aspired by a patient. Interposed into said channel is a narrow diameter nozzle venting compressed gas in the direction of inspired flow. By regulating the mass flow rate of compressed gas through said nozzle, variable levels of constant positive airway pressure can be produced.
