ABSTRACT:
The invention concerns a method and apparatus for indicating a parameter of a transmitted fluid. One embodiment of the invention comprises a fluid source operatively coupled to a conduit for transmitting a fluid from the fluid source. In addition, a sensor detects a parameter of the fluid, such as the percent oxygen content of the fluid. In response to the sensor detecting the parameter of the fluid, an indicator illuminates a portion of the conduit if a predetermined condition, such as a minimum percent oxygen content of the fluid, is satisfied.
