Pairing an Oxygen Concentrator with Your HBOT Chamber: 5L vs 10L

Why the concentrator matters

The chamber pressurizes with clean air. The oxygen a patient breathes comes from a separate concentrator that feeds a mask or hood inside the cabin. If the concentrator cannot deliver enough flow at the right purity, the session under-delivers — and the controller may alarm on low O2 flow.

5 LPM vs 10 LPM

• 5 LPM at 90–93% O2: enough for short 30-minute sessions or two chambers used alternately. Tight for a single chamber running 60–90 minute sessions back to back.
• 10 LPM at 90–96% O2: the sweet spot. Delivers steady flow through a full 90-minute session, and has headroom if you add a second chamber later.

What happens when they mismatch

Under-sized concentrators show up as: O2-flow alarms mid-session, patients reporting the mask "feels like air," and session logs that show purity dropping below 90% after 40 minutes. Clinics that cheap out on the concentrator end up buying a second one within 6 months.

Buying tips

• Buy a medical-grade concentrator, not an industrial one.
• Look for 90–96% O2 purity rating at the rated flow, not "up to 95%".
• You can buy a new unit locally or bundle one with your chamber order.
• We can bundle a concentrator with the chamber — same shipment, same paperwork.
