Abstract: A resuscitator apparatus including a resilient, self-inflating squeeze bag having a single combined inlet/outlet which is preferably removably connected to a first manifold in operative communication with a valve device. The first manifold includes an inlet coupling adapted for connection to a source of pressurized respiratory gas such as oxygen and an outlet coupling adapted for connection to a first end of a tubular connector. The second end of the tubular connector is adapted for connection to an inlet coupling of a second manifold in operative communication with a non-rebreathing valve contained within a tubular, preferably L-shaped housing. The tubular housing includes a first leg connected to the second manifold and a second leg extending substantially perpendicular to the first leg, the second leg being adapted for connection to a subject interface member such as a breathing mask.
