Drive Medical Bonsai Velocity Pneumatic Oxygen Conserver, Pack of 1, OM-812

The Drive Medical Bonsai Velocity Pneumatic Oxygen Conserver (Model Number OM-812) is a compact, lightweight oxygen-conserving device engineered to extend the duration of portable oxygen cylinders by delivering pulsed doses only during inhalation, featuring a durable all-metal construction that weighs just 0.3 pounds for discreet attachment to M2 through E-size cylinders without adding bulk or imbalance in home, travel, or clinical settings. Its pneumatic operation requires no batteries or electricity, providing reliable performance with settings from 1 to 6 LPM equivalent in continuous flow mode and a high 40:1 conservation ratio that can triple cylinder life compared to continuous flow regulators, while the dual-lumen cannula senses inhalation to trigger precise bolus delivery for optimal oxygen saturation and patient comfort. The easy-to-read flow selector with click-stop positions ensures accurate prescription matching, and the integrated pressure gauge monitors tank contents to prevent unexpected depletion, complemented by a barbed outlet for standard cannula connection and a built-in safety valve to avoid over-pressurization. Ideal for active patients managing COPD, emphysema, or post-surgical recovery who require portable oxygen during errands, exercise, or travel, this pre-calibrated conserver arrives ready for immediate use with comprehensive instructions and supports greater independence by minimizing tank changes and refills. Backed by Drive Medical’s one-year limited warranty against defects in materials and workmanship for the original purchaser when acquired through authorized dealers, this essential pneumatic conserver delivers enduring efficiency, reliability, and peace of mind for sustained respiratory freedom.
