Abstract
The disclosure is of an improved method and apparatus for humidifying medical gases. The apparatus improved is of the type which comprises a portable housing enclosing a water reservoir, a gas chamber, gas inlet and outlet conduits to carry the gas through the water reservoir and gas chamber. The improvement comprises an audible pressure relief valve in association with the gas chamber. When a predetermined pressure within the gas chamber has been exceeded, the pressure relief valve opens to relieve the excess pressure and to simultaneously warn the operator than the predetermined pressure level has been exceeded. The alerted operator may then check to determine if there has been a malfunction in the apparatus or ancillary apparatus.
