The CHAD Evolution Electronic Oxygen Conserver offered by Drive Medical is a superior oxygen saturation device.
Effective and Efficient: The Evolution delivers a uniform oxygen pulse which can range from 14 breaths per minute to 40, supporting a wide range of needs and activity levels. The Evolution Electronic Oxygen Conserver senses a breath and delivers oxygen only in the first half of the inspiratory cycle, resulting in no wasted oxygen while delivering an effective oxygen dose. In addition, the Evolution has a 5:1 savings ratio and liter flow settings between 1 and 7 LPM, providing a high level of conservation while offering versatile liter flow options. An auto shut-off feature conserves the battery life. It fits into most carry bags and has a minimum 2 year battery life with 2 AA batteries (with an average of 4 hours of usage per day).
Specifications: This Oxygen Conserver is compatible with CGA 870. The oxygen flows in liter increments of 1, 2, 3, 4, 5, 6, 7 and CF preset at 2 LPM. Its operating pressure range is 200 - 3,000 PSI. Just a single push of a button selects the equivalent LPM dosage settings. The device's dimensions are 8" L x 6" W x 4" H and it is lightweight, weighing only 1.31 lbs. It comes with a limited 2 year warranty.
