Oxygen
Stationary Oxygen Concentrators
Continuous-flow units built for the bedroom or living room, not the runway — for prescriptions above what a portable unit can deliver.
No waiting on a breath
A stream that never stops.
Where a portable meters a bolus per breath, a stationary unit runs an uninterrupted stream at a set flow rate the entire time it’s plugged in — the reason continuous flow reaches higher LPM prescriptions than a pulse-dose unit can cover.
Which one your prescription actually calls for, in portable vs. home oxygen concentrators.
What the output actually is
Mostly oxygen. Not pure oxygen.
Every unit on this page outputs 87–96% oxygen, not 100% — the sieve bed strips out nitrogen, not every trace gas in room air. That range is what you should expect to see printed on the label, not a rounder number.
How saturation and purity actually relate, in understanding oxygen saturation (SpO2).
