Dramatic Oxygen Savings and Long Battery Life!
The Evolution OM-900 electronic oxygen conserver from Chad Therapeutics is a remarkable device that can help you see 5:1 savings in your oxygen use. This electronic oxygen conserver operates on 2 standard AA batteries and can run for up to 2 years before needing new batteries! It's small size and lightweight design mean you can take this conserver wherever you go while the simple, single button operations avoids confusion and complexity.
Fantastic Performance and Sensitivity
The Evolution OM-900 gives you a 5:1 oxygen savings ratio over constant flow regulators. The electronic pulse-dose system ensures an accurate dose of oxygen during each inhalation cycle and also includes a 2 LPM emergency constant flow setting. The OM-900 will sense a breath within the first half of an inhalation cycle and is well suited for those who inhalations are lower than normal and that a pneumatic unit may not easily sense. It only weighs 14.9 ounces and the small size will allow you to use just about any cylinder/regulator carry bag! The OM-900 Oxygen Conserver has Liter Per Minute settings of 1, 2, 3, 4, 5, 6, 7 and, as mentioned before, a constant flow setting of 2 LPM making this unit flexible for a wide range of oxygen therapy uses. The OM-900 will accept standard nasal cannulas with up to a 7ft tube.
No More Frequent Battery Changes The OM-900 can perform for up to 2 years (when used an average of 4 hours per day) with standard alkaline AA batteries eliminating the need for frequent battery changes. The OM-900 oxygen conserver also includes a warning indicator to let you know if the battery life is getting low - keeping you from being surprised by suddenly losing oxygen supply! With the built-in Auto-shutoff feature, the OM-900 will automatically turn itself off when not in use, further saving your batteries from being drained.
Excellent 5:1 Oxygen Savings!
