摘要：A resuscitator that includes a ventilation mask structure for sealinglysurrounding a patient's mouth and nose, a gas flow manifold having passage structurefor delivering ventilating gas from a source of the gas to the mask structure, and amanually collapsible gas receptable operatively coupled to the gas flow manifoldcomprising a modular structure for detecting gas pressure in the manifold; the modularstructure including wall structure defining a bore, the modular structure defining a portstructure communicating with the gas flow manifold to communicate gas pressure in themanifold to the bore; a plunger slidably mounted to the bore, the plunger having aflange defined thereon; spring structure mounted intermediate the flange of the plungerand wall structure of the modular structure so as to limit movement of the plungerrelative to such wall structure of the modular structure; at least a portion of a wall of thewall structure of the modular structure being transparent, wherein such movement ofthe plunger relative to the transparent wall can be seen exteriorly of the transparentwall and wherein the transparent wall has indicia defined thereon whereby movement ofthe plunger relative to the indicia on the transparent wall indicates the pressuredetected by the plunger.
