"The bottom line is that the majority of GA pilots who fly normally-aspirated piston airplanes do so without any supplemental oxygen whatsoever. When they fly at altitudes above 5,000 to 10,000 feet (depending on the individual), they do so with some significant degree of hypoxic impairment. They can't think or see as clearly or make decisions as well as they should, and they get tired more quickly than they should. On those occasions where weather and/or terrain force them up above 12,500 feet, they also may be violating the FARs ... but frankly that's not my concern because I'm a doc, not a cop." - Dr. Brent Blue (read the whole article)

The E-Ox Model 425 Personal Emergency Oxygen System is a unique product designed to provide a convenient way to carry lifesaving supplemental oxygen with you when you're on the move. This convenient 425-liter system provides a 3.5 hour supply of oxygen when breathing oxygen continuously at the rate of 2.0 liters per minute, 14 hours if you use the optional Oxymizer conserving cannula, and as much as 21 hours if used in conjunction with the REACT oxygen conserver. Of course, no oxygen system is complete without a pulse oximeter to monitor your oxygen saturation to ensure you are getting the oxygen you need.

Your E-Ox Model 425 system includes:

• a 425-liter (D) oxygen cylinder
• shutoff valve
• gauge
• adjustable regulator
• mask and tubing
