Clarenceh9: How long do you leave the concentrator turned on?clarenceh9 wrote:I just turn off the apap and leave the oxygen on, as the concentrator machine BEEPS loudly when you first turn it on.
Is this not ok?
Hopefully not all the time.
The beeping is a 'warning' that there will be oxygen entering the area, which is a fire hazard.
The xpap mfgrs recommend that any oxygen concentrators be turned on AFTER the xpap machine, so that the oxygen does not flow into the xpap.
That is the reason for using the check valve, which prevents 'backflow'.
(reverse also true: turn off the concentrator, then turn off the xpap)
i.e., no oxygen unless the xpap is running.
I do not know if these check valves come in any material other than plastic, as that was what was provided me, and I thought it to be sufficient, since it's not exactly a high-pressure unit. .
