Description
The Drive Medical Bonsai Velocity Pneumatic Oxygen Conserver (OM-812) is a demand-pulse device that conserves oxygen by delivering a precise bolus only at the start of each breath, rather than flowing continuously. Operating across a pressure range of 200–3000 PSI, it is compatible with virtually all portable and ambulatory cylinder configurations. A single selector knob covers six demand-flow settings plus two continuous-flow presets (2 LPM and 4 LPM), and the quiet, lightweight design fits into most standard oxygen carry bags without modification. Importantly, the Bonsai Velocity delivers a uniform pulse regardless of breathing rate — so users receive the same amount of oxygen whether breathing slowly or rapidly.
