Drive Devilbiss Smartdose Evolution Oxygen Conserver
Drive DeVilbiss SmartDose Evolution Electronic Oxygen Conserver
5:1 Savings (Extends Tank Duration)
14.4 oz (408 grams) Lightweight Profile
Hard-Coded 2.0 LPM Continuous Flow Override
Executive Product Overview
The Drive DeVilbiss SmartDose Evolution Electronic Oxygen Conserver (Model OM-975) is an auto-titrating pneumatic gas management device engineered to maximize compressed oxygen cylinder duration. Blending the auto-titrating electronic microprocessor architecture of the SmartDose platform with the rugged mechanical housing of the CHAD Evolution series, the OM-975 automatically scales oxygen bolus delivery based on patient respiratory rates.
Weighing only 14.4 ounces, the OM-975 monitors breathing frequency across cycles ranging from 14 to 40 breaths per minute. As physical activity increases inspiratory rates, the system automatically expands bolus volume, stepping dosage back down during resting states to achieve a 5:1 gas savings ratio compared to continuous flow regulators. Powered by two standard AA alkaline batteries providing up to 1 to 2 years of operational life, the device features a hard-coded mechanical continuous flow override (2.0 LPM) that bypasses electronics during complete battery depletion.
Key Performance & Operational Features
- Auto-Titrating Variable Bolus Delivery: Microprocessor software automatically adjusts pulse volume in real time based on active physical exertion.
- 5:1 Gas Conservation Ratio: Dramatically extends cylinder operational life, quadrupling untethered time for ambulatory patients.
- Hard-Coded Mechanical Safety Override: Manual rotary dial switch to "CF" position engages a 2.0 LPM continuous flow safety stream without battery power.
- High-Pressure System Compatibility (Up to 3,000 PSI): Engineered for high-pressure HomeFill filling systems as well as standard pre-filled medical tanks (M6, M9, D, and E cylinders).
- Intelligent Energy Management: Operates for 1 to 2 years on two standard AA alkaline batteries with an integrated sleep mode during inactivity.
- Uniform Pulse Delivery (Up to 40 BPM): Maintains full therapeutic bolus volume even during rapid respiratory exertion.

Facility Procurement & Risk Mitigation Insight
Standardizing cylinder fleets on the Drive DeVilbiss SmartDose Evolution OM-975 lowers oxygen refill costs via its 5:1 conservation ratio. The mechanical 2.0 LPM continuous flow override mitigates apneic risk during battery drain, while compatibility with high-pressure systems up to 3,000 PSI allows seamless integration with HomeFill and transfill operations.
Product & Compliance FAQs
Q: Why does the SmartDose Evolution OM-975 require an official medical prescription?
A: The FDA classifies electronic oxygen conservers as Class II Prescription Devices because they connect directly to high-pressure compressed medical gas cylinders to meter a regulated drug (medical oxygen) into a patient's respiratory tract.
Q: What happens if the internal AA batteries drain completely during patient use?
A: The OM-975 includes a mechanical continuous flow safety override loop. Turning the top control dial to the "CF" position engages an internal mechanical valve that bypasses the microprocessor, delivering a continuous stream of oxygen at 2.0 LPM without battery power.
Q: Is the OM-975 conserver compatible with HomeFill high-pressure tanks?
A: Yes. The high-pressure seals inside the OM-975 are rated for continuous operating pressures up to 3,000 PSI, making it compatible with home-filling cylinder systems and standard CGA 870 post-valve cylinders.
