McKesson 5 Liter Compact Oxygen Concentrator with OSD: A Complete Guide
A space-efficient stationary concentrator built for institutional and long-term care bed placement — continuous flow from 0.5 to 5.0 LPM with real-time purity monitoring via McKesson's integrated OSD sensor.
For standard continuous-flow oxygen prescriptions in institutional or long-term care settings, a reliable, space-efficient 5-liter unit is often the right fit — no more capacity than the patient needs, and a compact footprint that's easy to place bedside.
