The patented MH EDS Pulse-Demand™ devices have precision micro-electronic circuits that automatically adjust the volume of each oxygen pulse according to pressure altitude. Increase in altitude are compensated with pulses of greater volume. The MH EDS can be set to a mode where it will not deliver oxygen below pressure altitudes of either 5000 or 10,000 ft., saving oxygen below altitudes where it is not needed. It can be set to another mode where it delivers oxygen at all pressure altitudes. Both modes provide the same amount of oxygen for a given altitude and automatically track altitude changes. In addition, there are four additional modes to accommodate face masks or users who need extra oxygen. There are no scales to observe or knobs to turn as you climb or descend. Adjusting for climb or descent is not needed because the MH EDS responds automatically to pressure altitude. The MH EDS is a truly automatic hands-free oxygen delivery system that enhances your safety and comfort.
When you’re flying, don’t you have more important things to do than adjust your oxygen flow during altitude changes?
The patented MH EDS (Electronic Delivery System) is a one (O2D1-2G) or two-user (O2D2-2G) aviation oxygen delivery device. It is designed to deliver aviation oxygen in the most efficient, comfortable and convenient way possible. With its user-selectable settings, apnea alarm and small size, the MH EDS O2D1 is the most portable and flexible electronic digital oxygen delivery system in the world. By providing a measured pulse of oxygen every time you breathe in, the MH EDS supplies the oxygen you need to stay alert and comfortable while flying. In contrast to constant flow systems that waste oxygen by supplying more than your body can use, the MH EDS provides a short pulse of oxygen as you inhale, ensuring that your oxygen is used most efficiently. Efficient oxygen delivery means you can fly further on a single oxygen refill or save space and weight with a smaller tank. It also makes it more feasible to enjoy the advantages of oxygen while flying below the altitudes where oxygen is mandated– that can mean fewer headaches, increased alertness, and feeling less exhausted when you reach your destination. Your actual oxygen usage will be determined by your breathing rate and physiological needs at altitude. The programmability of the MH EDS means that, unlike constant-flow oxygen systems, you can “set it and forget it”. By automatically detecting your pressure altitude, the MH EDS can be set to start providing oxygen immediately or at a specified altitude and will automatically adjust the oxygen flow as your altitude changes.
