ABSTRACT OF DISCLOSURE : The breathing apparatus comprises a first inspiration circuit formed by a pair of inspiration manifolds in series disposed with interposition of flow regulating means. A pres- sure stabilizer and governor is disposed upstream of said pair of inspiration manifolds and it comprises a constant volume reservoir connected to a source of fluid in pressure and containing an inflatable balloon connected to said first inspiration balloon. A microswitch is closely disposed rela- tive to said inflatable balloon for detecting the volume changes thereof and controlling flow intercepting means dis- posed in said first inspiration circuit. A second expiration circuit is directly connected to the atmosphere with inter- position of flow regulating and intercepting means. In alter- native, the second expiration circuit comprises a pair of expiration manifolds in series disposed with interposition of flow regulating means, a first manifold of the pair being connectible to the atmosphere and a second manifold of the same pair being connectible to a vacuum source (Fig. 2).
