Managing your oxygen therapy on the go demands a conserver that keeps pace with your activity — not one that forces you to stop and manually adjust settings. The SmartDose Evolution electronic oxygen conserver does the work for you, continuously monitoring your breathing rate and automatically scaling the delivered bolus to match your demand. Whether you're resting at home or moving through your day, the device senses the change and responds in real time, maintaining your prescribed oxygen levels from 14 to 40 breaths per minute without any manual intervention.

You get seven individually selectable bolus settings — 1 through 7 — plus a continuous flow preset fixed at 2 LPM, giving you and your clinician full flexibility to dial in exactly the right therapy level. The pulse-dose delivery mechanism releases oxygen only during inhalation, eliminating the waste of continuous flow and extending your cylinder life by up to five times. At 14.4 oz and sized at just 4.0" x 6.5" x 3.3", it fits comfortably in a carrier bag without adding noticeable weight to your routine. Two standard AA alkaline batteries power the unit for up to two years with the auto shut-off feature protecting battery life between uses. The CGA 870 connection is compatible with virtually all standard home oxygen cylinders, making the SmartDose Evolution a practical upgrade for any ambulatory oxygen system.
