A manometer integrated into a manual resuscitator includes a housing with a communication path, and a pressure gauge integrally forming part of the housing. A sensing chamber and an atmospheric chamber are separated by a diaphragm subject to distortion by differential pressure between the chambers, with a spring to restore the diaphragm upon equalization of the pressures. A shaft journaled in a first bearing on the diaphragm and a second bearing in one of the chambers rotates in the bearings upon diaphragm distortion, and an indicator on the shaft indicates differences in pressure between the chambers.

What is claimed is: 1. A patient breathing apparatus comprising: a housing having an inlet and outlet configured to communicate respiratory air and connected by a communication path; and a pressure sensing means for sensing a pressure in the communication path, the pressure sensing means being integrally mounted with the housing to the extent of not being separable from the housing without damage to the housing or sensing means. 2. A method of providing breathing assistance to a patient comprising: supplying breathing air to the patient through a housing having an inlet and outlet connected by a communication path; and displaying the pressure of supplied air in the housing on a pressure gauge integrally mounted to the housing by distorting a diaphragm from a rest position upon a differential pressure between two chambers in the housing and restoring the diaphragm to the rest position upon equalization of the pressures in the chambers, thereby moving an indicator coupled to the diaphragm to indicate differences in pressure between the chambers. 3. A manual resuscitator apparatus comprising a housing having an inlet and outlet connected by a communication path and a valve means operably associated with the communication path; and a pressure sensing means for sensing a pressure in the communication path, the pressure sensing means being integrally mounted with the housing to the extent of not being separable from the housing without damage to the housing or sensing means.
