Abstract
A system and method of providing a wireless heads-up display for displaying the amount of breathing gas remaining in an associated breathing gas supply is provided. The system has a transmitter and a receiver. The transmitter has a pressure sensor and a controller for interpreting the sensed pressure into levels indicative of the amount of breathing gas remaining in the breathing gas supply. These levels are transmitted via radio frequency to the receiver. The receiver, which can be mounted in a breathing mask, includes a display for displaying the amount of breathing gas remaining in the associated breathing gas supply.
