ABSTRACT:
A resuscitator that includes a ventilation mask structure for sealingly surrounding a patient's mouth and nose, a gas flow manifold having passage structure for delivering ventilating gas from a source of the gas to the mask structure, and a manually collapsible gas receptable operatively coupled to the gas flow manifold comprising a modular structure for detecting gas pressure in the manifold; the modular structure including wall structure defining a bore, the modular structure defining a port structure communicating with the gas flow manifold to communicate gas pressure in the manifold to the bore; a plunger slidably mounted to the bore, the plunger having a flange defined thereon; spring structure mounted intermediate the flange of the plunger and wall structure of the modular structure so as to limit movement of the plunger relative to such wall structure of the modular structure; at least a portion of a wall of the wall structure of the modular structure being transparent, wherein such movement of the plunger relative to the transparent wall can be seen exteriorly of the transparent wall and wherein the transparent wall has indicia defined thereon whereby movement of the plunger relative to the indicia on the transparent wall indicates the pressure detected by the plunger.
