ABSTRACT:
A method of verifying function and status of breathing equipment, wherein the breathing equipment includes a gas supply, a closure valve on the gas supply, a primary pressure regulator downstream of the closure valve, a pressure sensor, a secondary pressure regulator downstream of the primary pressure regulator, a breathing mask downstream of the secondary pressure regulator, an indicator, a processor connected to the pressure sensor and the indicator, and gas lines between the gas supply, the primary pressure regulator, the secondary pressure regulator, and the mask. A processor for receiving sensed data, comparing the sensed data to control values, and producing an output signal is activated. At least one functional or status variable within the equipment is measured. The at least one measured value is compared to a corresponding control value with the processor. An output signal based upon the comparison is produced. The output signal is transmitted to an indicator to indicate whether the at least one measured value substantially corresponds to the at least one control value.
