M series Auto BiPap

Gerryk · Post by **Gerryk** » Thu Jan 01, 2009 1:10 pm

Hello, newbie here to this forum. I am newly back on cpap and have a new machine that I am having some problems with. I have a Respironics M series Auto BiPap. I have had a problem with the machine turning off when I lift the mask to adjust it or take the mask off for a short amount of time. I do have the function turned off that turns the machine off when the mask if removed. When this happens I am unable to turn the machine back on without unplugging the unit. I end up with the blue lights flashing. I have had the machine turn off when I burp too.

I understand there were some or was a recall on these units but mine is brand new and doesn't match the numbers of those recalled.

I did a search on here and was unable to find the info on the problems this machine had. I would just like to compare the problems and see if they are similar.

Thanks for your help.
Gerry

DON'T DO THAT!

Seriously, though......I haven't heard of that problem (specifically) before. So, I'm not sure what advice to give other than if it doesn't turn off when your mask is constantly attached and you DO have the "Auto Off" option turned "OFF", you might discuss it with your equipment provider. I suppose it could be possible that there's a sensor that's connected to the Auto Off function that's malfunctioning.

I went and talked to my DME supplier the other day and they ordered a new machine and said I will keep the same humidifier. I said I think there is also a problem with the humidifier because it got extremely warm where you plug it in. The new machine is supposed to be in today.

Last night I think I woke up and the machine was in the process of shutting off and the lights were flashing. The machine then turned right back on and went up to pressure. I have a feeling this is what has been waking me up since I started on this machine. During my titration on BiPap I slept through the night which I haven't done in years. Since I got the machine I haven't slept through once and I believe it is a defective machine that has caused that. I will update when I have the machine and have used it a few days.

I had the same thing happen the next night where the machine turned itself off and back on during use. I didn't get my new machine until yesterday the DME said they were too busy to stay on hold with the manufacturer last Friday so it wasn't ordered until Monday. I have it with the same old humidifier. I didn't notice the problem last night but I didn't sleep well either. The humidifier did not seem to work correctly either it was on and off.

3 things come to mind -

machine shuts itself off because it senses a large leak - fix by disabling auto off

machine is turning off because of a faulty power brick - fix by demanding a new machine (this has been reported on this forum by others with m series machines)

machine shuts off because of a power outage - ask your electric company if there have been small outages

No power outage.

Auto off was not of my DME double checked that.

I did get a new machine and a new power brick which is very different than the old one.
I will keep an eye on the humidifier tonight as I belive the lights on mine were not on the whole night last night.

I have the same machine and haven't had any problems at all. I suspect you do have a defective unit.

Had, I have a rebuilt one now. As I figured their was a problem with the machine all along. I slept fairy good the night I got the machine and slept through last night. That's the first night in years other than my titration that I slept through the night.

I am curious about the new power brick - what are the ratings (on the bottom)?

Thanks

I just got back from the supplier with a new machine. Was issued my first Auto BiPAP two weeks ago and was unhappy from the start. The inhilation pressure would cut out just before I started to exhale causing a "burp". I got used to that but then last week I woke up to find the machine totally off. It came back on when I pushed the power button but went off again a few minutes later. That may have been due to the fact that the mask was leaking. Next it decided to turn itself ON during the day. That happened twice (hose was on the machine) and I had to unplug it to keep it from running. Yesterday I took the hose off to dry it out (heated humidifier) and the machine once again turned on by itself, not once but twice. For the last several nights I was wakened by a feeling that the machine was sucking air out rather than blowing in during inhilation. About four this morning I discovered what was happening - the inhilation pressure was cutting back too quickly so I had the sense of a vacuum before I exhaled. That did it! I called the supplier and got the usual "runaround". He asked if it showed "ERROR" in the window but I told him it thought it was doing OK. Then the machine started up on its own while we were talking and I guess that convinced him there was problem. I took the machine back and since it was a rental (HMO pays for it) and under warranty they gave me a new one. Will report on how this one does. They also included a new transformer (my old one did get pretty hot). I know this is a pretty sophisticated machine but there seem to be a lot of problems with it.

I have been using the Respironics BiPAP Auto M Series with Bi-Flex + Humidification and I have had the same problem with two different units from two different DME providers so I do not think that the units had failed.

My pressures are 24/20 on auto. The unit is NOT set to auto off. 10 foot hose.

This problem happens when wearing either the comfort gel nasal or full face mask. Sometimes during the night I will lift the mask from my face to let it reseal and the BIPAP will stop putting air out. The mask is not off of my face for more then a few seconds when this happens. I will have to take a few deep breaths to get the unit working again. I have also woke up and have found that the unit is not pushing any air out. This does not happen when wearing nasal pillows.

The people at Respironics believes it might be a combination of the high pressure and the 10 foot hose. I am going to get a shorter hose and try it.

Any suggestions? Thanks.

Shorter hose may help. Which mask?
Some have another 18inches of hose on them. You could try removing that, if you have it.

I have had my replacement machine for a while now. I have not had any problems with it, it has not turned off by itself, it has not gotten hot on the back by the power plug and I have been sleeping through the night more than not.
I did forget to get the info on the power brick but it is different.
I had to prove to my dme that there was a problem then they wanted to check the setting which was fine but they though maybe I had played with it. Anyway, I got a different machine. I got a refurbished unit not a new one. I wasn't happy about that because my unit was less than two months old, but at least I have a unit that works and I am sleeping.

I tried a shorter hose, 6 ft. and still have the shutoff problem. I have many masks and have the shutoff problem with all except the nasal pillows. My pressure settings have been change to 22/18 and the shutoff problem still exists.
I got a replacement unit today. The unit and the humidifier are rebuilds so I am not going to accept them. I had the original unit for only a week. Also the firmware version on the replacement is 4.3 compare to 5.53 on the original unit. I will try the new power brick tonight to see if that was the problem.

Hello, all.
I am now on my second M Series BiPap, and continue to have the same problem with the unit shutting itself off repeatedly during the night. I too wear a full face mask. As if this weren't bothersome enough, the unit beeps repeatedly and I get a "blue light special" until I disconnect the power from the unit and start over. Anyway, it's annoying-- for the cost of these machines (or DME rental, of course...) you'd think they'd do a better job engineering these things. While my DME has given me a another new machine, I'm frustrated that I am stil lhaving this problem. I'll try the auto-off setting and see if that improves the situation. (If anyone has something else to share on this, please do. Thanks!
