Abstract

Breathing apparatus includes a container (1) which contains a compressed breathing gas. A gas reservoir (3) is coupled to a outlet (2) in the container (1) and a mouthpiece (5) is coupled to the gas reservoir (3). A gas flow control device adjacent the outlet permits a substantially continuous flow of gas from the container (1) in use. The apparatus includes a water CO<SB>2</SB> isolation tube which enhances performance as well as reservoir vent valve positioned to aid operation.
