Mountain High Oxygen is pleased to announce the release of our next generation of EDS (Electronic Delivery System) Pulse Demand oxygen controllers, the O2D1-2G and O2D2-2G.
These changes are common to both the O2D1 and O2D2 family of EDS.
Our new Pulse Demand systems still incorporate all of the benefits of our legacy controllers but with many improvements. Like the series of the old VW Beetle, it’s the same, but better.
We started with the control switch: The EDS unit now incorporates a MIL spec ruggedized easy-to- grip rotary control switch providing improved reliability, increased ease of function and visibility. This switch also has very positive position detents for excellent tactile feedback making it resistant to changes from causal rubbing or bumping.
While we were at it, we improved the manifold design to allow for better breathing response and effort tracking. This combined with a new circuit board, as well as a new micro-controller, gives improved power-conserving operations with even less RFI emissions, better respire-metric tracking and dispensing of oxygen in finer resolution resulting in smoother steps from altitude and breathing changes.
Other improvements include a dedicated bi-color system battery status light allowing much easier monitoring and definitive indication of battery condition without being confused as a station operation. The original O2Dx units encoded the low battery notification into the station lights. This status light also responds to each control switch change with a beep and green flash to confirm your actions. Also the audio alerts and warnings are louder, more crisp and dynamic to human hearing in an effort of being heard over modest cabin noise. The O2D2 has a 600 Ohm stereo external audio jack as well as a USB compatible (5VDC) external power port.
More intuitive F-Mode settings labeled as 1, 2, 3 & 4 for use with face masks or when more oxygen is required.
How Pulse Demand Works
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 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. When you’re flying, don’t you have more important things to do than adjust your oxygen flow during altitude changes?
The EDS-O2D1-2G System enables the general aviation pilot to fly at pressure altitudes up to 25,000 feet with safety and comfort. The EDS-O2D1-2G digital Pulse- Demand™ system reduces Oxygen consumption dramatically. Different from the “standard” constant flow systems, the EDS-O2D1-2G Pulse-Demand™ system wastes no Oxygen during the breathing cycle when oxygen is is not being delivered to the lungs. The average user will enjoy a duration increase of two to three times compared to the constant flow systems.
The built in Barometer adjusts for Altitude increase while reducing the pilots work load.
Abandoned unit auto shut off: If you should forget to turn your EDS off after use, it will now go into auto shut-down (drawing very little power) after 3 hours of detecting no use in an attempt to save the batteries for another flight.
The unit operates for up to 100 hours on two AA batteries.
The EDS-O2D1-2G should be used with any of our XCR, XCP, or 4-place FPR regulator. for correct pressure and oxygen delivery. The low-pressure service line is a high quality polyurethane line that is kink-resistant and flexible under varying temperatures. The cannula, face mask and service line connect to the EDS unit via color-coded “Quick-Connects” providing an air-tight fitting by hand. These fittings can be connected and disconnected many times. With the optional XCP connecting kit, the EDS can be used with an XCP system at the same time flow meters are being used. In addition, the optional ALPS Facemask with or without microphone, is the perfect addition to any EDS system.
