O2D1 Pulse-Demand™ Oxygen Single Person System

Overview

The Mountain High EDS O2D1-2G is a compact oxygen delivery device which delivers an altitude-determined pulse of oxygen only when the user inhales. The O2D1 enables pilots to fly safely and comfortably at higher altitudes while minimizing oxygen consumption through fully automatic, hands-free operation.

Pulse-Demand™ Advantage: More Oxygen Where It Matters

Unlike constant-flow oxygen systems that deliver oxygen continuously—wasting much of it during exhalation—MH EDS Pulse-Demand™ technology supplies oxygen only when you inhale, ensuring oxygen is delivered precisely when it can be absorbed by the lungs. This targeted delivery improves oxygen utilization, helping maintain better blood oxygen saturation with less overall oxygen consumption. Pilots often experience increased alertness, reduced fatigue, fewer altitude-related headaches, and improved overall comfort, especially during longer flights. By automatically responding to pressure altitude, the EDS provides efficient, hands-free oxygen delivery throughout climb, cruise, and descent—without the need for in-flight adjustments.

Highly Efficient: Oxygen Only When You Inhale

MH EDS Pulse-Demand™ technology delivers a precisely measured pulse of oxygen only during inhalation, eliminating waste during exhalation and pauses between breaths. Unlike constant-flow systems that continuously supply oxygen whether it is needed or not, the O2D1-2G utilizes nearly all delivered oxygen efficiently.

This high efficiency allows pilots to fly longer on a single oxygen refill or reduce weight and space by using a smaller oxygen cylinder. Efficient delivery also makes it practical to use oxygen at lower altitudes, often resulting in improved alertness, fewer headaches, and reduced fatigue.

Easy to Use: No Manual Adjustments Required During Flight

The O2D1-2G automatically adjusts oxygen pulse volume based on pressure altitude using internal micro-electronic circuitry. As altitude increases, pulse volume increases automatically—no pilot input required.

The system can be configured to begin oxygen delivery above 5,000 or 10,000 feet, or to deliver oxygen at all pressure altitudes. Additional modes accommodate face masks or pilots who require higher oxygen levels. With no flow indicators to monitor and no knobs to adjust during climb or descent, the EDS lets pilots focus on flying.

Powered by Simple AA Batteries

The O2D1-2G operates for extended durations on standard AA batteries, with a low-battery warning alerting the pilot when remaining power is limited.
