ABSTRACT:
An apparatus and related method for selectively dispensing oxygen into an enclosed space is provided. The apparatus includes a pressurized container comprising oxygen and an actuator which can be moved between discharging and non-discharging positions, a means for mounting the pressurized container such that upon discharge the container will dispense oxygen into the enclosed space, an electrically-operable actuating means which effects movement of the pressurized container actuator between the discharging and non-discharging positions, and a sensor disposed in the enclosed space and in electrical connection with the actuating means for detecting a preselected property of the atmosphere in the enclosed space, wherein when the sensor detects the certain preselected property, the actuating means moves the aerosol container actuator into the discharging position, thereby providing for oxygen to be discharged into the enclosed space.
