1. A manual resuscitator apparatus comprising:

  • a housing having an inlet and outlet connected by a communication path to permit air flow through the communication path;

    a pressure gauge forming part of the housing having a sensing chamber in communication with the communication path and an atmospheric chamber in communication with ambient atmosphere, the chambers being separated by a diaphragm subject to distortion from a rest position upon a differential pressure between the chambers, with a spring associated with said diaphragm to restore said diaphragm to a rest position upon equalization of the pressures in the chambers;

    a first bearing attached to said diaphragm and a second bearing in one of said chambers;

    a shaft journaled in said bearings for rotation in one direction upon diaphragm distortion and rotation in another direction by diaphragm restoration; and

    an indicator associated with said shaft to indicate differences in pressure between the sensing and atmospheric chambers causing diaphragm distortion.
