Portable concentrator machines

A portable concentrator machine is a small device that can give mobility outside the home. Portable concentrator machines are not suitable for everyone and are only available after a specific ambulatory assessment has been completed.  Portable concentrator machines have the ability to use mains, battery and DC power supply, and are designed to work on pulse dose delivery.

A patient’s flow setting on one of these may vary from what they are required to use on a standard concentrator machine or cylinder.

  • When not in use for an extended period of time, please remove the battery from the Inogen and store separately
  • Your Healthcare Technician will advise on the placement of the filter and battery.

Safety guidelines to inform patients:

  • Keep the Inogen and the power cord away from hot surfaces and naked flames

  • If the Inogen has been dropped, damaged or exposed to water, please contact Baywater Healthcare for inspection or possible repair
  • Do not drop or insert any objects into any opening on the device
  • Do not block the air inlet or the exhaust vent when it is on a soft surface, such as a carpet, bed, couch, chair or vehicle seat
  • Do not cover the device with a blanket, towel or quilt etc
  • When using in a vehicle, be sure it is properly secured, belted or otherwise restrained
  • Do not leave your Inogen, or power cartridge, in the seating area or boot of your motor vehicle during a hot day
