Devilbiss healthcare was notified of an incident involving an oxygen concentrator by the end user, who reported that the tubing caught on fire while on the floor.The end user stated the concentrator was "running hotter than normal, has been humming with a yellow light" for two months.However, the end user stated that the machine itself did not catch on fire.All signs of fire were at the distal end of the cannula, and there were no signs of concentrator involvement.The end user stated that there were no open flames or smoking around the unit, so the fire's ignition source is unclear at this time.There is no report of any injury.The user manual for the oxygen concentrator states for yellow light with alarm to "contact your oxygen equipment provider for assistance and to arrange for servicing of the unit".Devilbiss healthcare is in the process of facilitating the return of the product for inspection and will update this report should any additional information become available.
