[CPAP] Machine shuts off and unidentified icon/symbol appears
#1
Question 
Machine shuts off and unidentified icon/symbol appears
Hello,

I am using a borrowed Resmed Airsense 10. My older machine broke down so I am this until I can get a new sleep study next month and a new machine. 

I have been on CPAP since 1997 and I feel confident I have the correct settings on this borrowed machine.  My pressure setting is 20 (yes, that is what is prescribed) and humidifier is set on 3 if that makes a difference.


I have been using this particular CPAP for 3 nights. Last night the machine shut off for no apparent reason. The power supply -ok, tubing-okay, mask fitting- okay. I turned the machine back on and it ran for about 5 seconds then cut off. I tried turning it on several times and the same thing happened.  There was no indication on the user data display that there was any problem except I noticed a flashing icon that appeared to look like a an asterisk (sort of) located next to the power bar display.  I have searched a user manual I found online. I was unable to find any reference to that icon anywhere in the manual.

I am hoping someone can enlighten me on this issue.

I am new to this website and I hope I have posted this in the right place. If I have not, please advise.   

Thanks

I believe the flashing indication is showing you the humidifier is in cooling mode after being shut down. I would turn off the Smart start setting if it's on and see if this takes care of the problem.

Can you swap out the power brick with your original machine just to double check the power supply?
Also, see Walla Walla’s suggestion above.

With that said, Welcome to Apnea Board!  

Since you will be having a new sleep study soon, here is some information on choosing a new machine.

What pressure is it trying to deliver, the machine WILL shut down after 6 seconds if it max out pressure.
Check the power supply is properly connected and make sure you have no big leak anywhere.

O for more than 1 sec

What to do is:
Check the power supply is properly connected.
Check it is set for the proper mask and tubing (hose)
To do this you will need to enter the set up Clinicians menu.
Press and hold the bottom button and the round one for several seconds.
After it changes, scroll down to check it is set for the correct tubing, correct mask.
Correct APAP/CPAP.
To change the setting:
If the setting is wrong, push the round knob and then turn the know to select the correct setting, press again and scrol down to the next setting.
If it is set to CPAP, you may want to try APAP, just change it, but you will need to set the Min to something like 16 and the high to 20 or max.
If your pressure setting is 20, the machine might not need a huge leak to think it has a fault and cause it to shut down.
See above quote.  It will try to keep 20 as your pressure, but if it can't because of a leak, it might shut down after 6 seconds.
To come out of the set up menu, just put it to home and press home.
It should return to the menu you normally see, if it does not, press home again.
Now you should see only the last sleep report and the minimum settings the user is allowed to adjust.

If everything checks out, phone who supplied the machine.
If you are not sure or do not want to touch the machine, they may be able to do this remotely, you just have to get them to check it is set for the correct tubing, mask and pressure.

If it is set to run CPAP, it might be worth changing it to APAP, but that would be your choice.
It would need to be set at 16 - 20 but check there is not a fault before you even try that.

I also found that if the device exceeds 40 in pressure for one second it will shut down,
mind you there would be a big noise change in the machine at that speed. P17 of the manual.  I can't remember what page the other one was on.
There appears to be differences in the British and American manuals?
I am NOT a doctor.  I try to help, but do not take what I say as medical advice.


Every journey, however large or small starts with the first step.

Sleep-well

I’m thinking SmartStart is on and it’s spooking you.


Incidentally, if you have a nose mask, you have to breathe through your nose with your mouth shut in order for SmartStart to kick in. Otherwise ..... Eat-popcorn .
