Gap in Therapy Graph? Is CPAP going off?

[azmanatheart]

Hi,
I've seen this once before, and I thought maybe there was a power failure. But this time, there is not only a 'blacked out' portion o f the time graph, there is 1 1/2 hour break in the middle of the night where it looks like my cpap machine was turned off, or shut off, I can't tell what this means, but it can't be good.

Can someone look at this graph and tell me what's happening. please.

you have auto off so when you spring a large leak it turns off?

notice you got a big leak before that

[azmanatheart]

I checked, Auto Off is set to 'OFF".

Looks alot like my husband's graph...right before he takes his mask off in the middle of the night when it does that. He does not remember taking it off, but the graph is almost identical to yours...big spike (pulling mask off while machine running, then shutting machine off).

If I had to guess, I'd say you're pulling it off, then putting it back on later....and "sleeping" through both events.

Ignore the gap for a minute -- everything else about the report is a mess of missed data too: no event counts at all, no index calculation, no data in the "events per pressure chart" --

Weird as anything.
Does your LCD data make any sense?
How do you feel?

Can you set up the software on another computer for comparison purposes?
How do other nights look - do you have all the data on previous charts?

Could this be Respironics latest attempt to fix the missing one or two days of data with 1 hour missing and no data for the whole day? I love Respironics Auto machine with Aflex, just wish they would fix the bugs.

I understand (via PM) the the missing data on the chart (except for the gap) is a pdf to jpg coversion fluke.
Which makes my above comment irrelevant.

Could you simply copy the graphs from the PDF and paste then into "Painter" and save as a jpeg file?
I'm not sure I understand what you mean by a " 'blacked out' portion o f the time graph".

Ozij- Thanks for the tip, I used Picasso, (for those who don't know, free photo editing software from Google).
I am pasing the charts below, which will hopfullyu be more useful and informative.

The 'black' part refers to the black time section that tops off the green time on the bar chart, it is recording time but with no therapy, I think?

Please let me know what you think this aprox 1.5 hours of no recording of data means. I can see, as Jules noted, that a very large leak preceeded this, but as I mentioned, the 'auto off' is definately set at 'off''In one of my earlier posts, you mentioned that the sleep doctor shouldn't have looked at 30 minutes at a pressure of 16 constitutes a final titration number, and I've gone to a Neurologist who believes as you do, that the technician in charge probably raised the level unnecessarily high chaing centrals possibly caused by so much pressure. I have a new sleep study this weekend, and I am hopeful to get a better analysis of my partucular situation, which is very tough to handle and get positive results and effective therapy unless I sleep on my side or belly. There is a very strong positional component to my apnea. Based on some of the groups recommendations, I raised the lower limit to 10, and the ceiling to 19. On nights when I stay on my side, the apap only goes up to about 12, but on my back, the pressure spikes up and the leaks are unmanagalbe, unless I use silicone putty, which softens the masks outer flaps permanently and makes it unusable thereafter without silicone putty.
Thank again for you input.
I'm thinking of trying to find a bed or massage table where I can sleep with my face down and maybe avoid apneas all together?





Thanks again to everyone who has helped.

Jeff,
Since you're using a full face mask, you may have continued sleeping with the mask on and the antiasphyxia valve doing what it was meant to -- which is let breath fresh air when your machine is not working. Does your machine turn on automatically when you breathe?

Is there any chance the electircal connection (on either machine or wall) may have jiggled and disconnected temporarily?

The alternative could be taking the mask off (and putting it on) and controlling the machine, without remembering. Some of the medications people take for sleep my have that effect on their memory.

I'm glad you're having a new sleep study.

if you have a pdf file, there is a tool in "select and zoom" that will allow you to do a screen shot -

snapshot tool - it is the bottom on my list

you scroll over the area and copy it - you can then copy it into paint (or where ever you want)

I see it lists only 4 min in LL - something strange is going on - we have seen m series shut off on a few cases before -- I would test to see if the auto off thing really is working right but taking the card out (if you don't want the session recorded), putting on the mask for a while, deliberately taking it off, and seeing if the machine really shuts off - I would repeat this several times.
