What to do if Inogen Medical Equipment concentrator does not power on?

E
Edwin FarrellJul 27, 2025
If your Inogen medical equipment concentrator doesn't power on, there are several potential causes. First, the battery might be discharged or not present, so use an external power supply or replace it with a fully charged battery. Second, the AC power supply might not be connected properly; check the connection and verify the green light is solid. Third, the DC cable may not be correctly connected; check both ends. If none of these steps work, it may be a malfunction, and you should contact your equipment provider.

Victor WalkerAug 10, 2025
If you're not getting any oxygen from your Inogen medical equipment, it could be due to a couple of reasons. First, the concentrator might not be powered on, so try pressing the On/Off button. Second, the cannula might not be connected correctly, or it could be kinked or obstructed; check the cannula and its connection to the concentrator nozzle.
