Pulsing digital oxygen controlPulsing digital oxygen control

Mountain High Equipment and Supply unveiled its new MH EDS-02D1 and EDS-02D2 pulse demand digital computer oxygen delivery systems at Expo. Mountain High, of Redmond, Ore., has been developing and marketing technology for 26 years that automatically profiles the amount of oxygen needed, and then delivers that precise amount of oxygen, said CEO Robert Jamieson.

Mountain High’s system does not dispense oxygen during the two-thirds of the breathing cycle— exhaling and pausing before inhaling again— when oxygen is not being delivered to the lungs. This pulse demand system consumes four to six times less oxygen than a constant-flow system, Jamieson explained. It monitors oxygen consumption to prevent hyperventilation. “Consequently, it eliminates that feeling of anxiety that one gets,” he said. Operation is automatic after the system is turned on, and it adjusts automatically to any altitude up to 25,000 feet.

The latest system employs new algorithms that allow the system to profile breathing characteristics very precisely. The single-place system costs less than $1,000, and a two-place system starts at $1,089. They can be expanded to accommodate additional passengers. For more information, see the Web site.
