question on resp rate and tidal volume, racing heart rate

I hope you guys are right. One strange thing is that they happen around the same time at night. I usually have a rapid heart rate at 1am-1:30am, 3-3:30am, then I wake up every hour to 1.5 hours. Strange to me how consistent it is. Thanks for the info on your REM thoughts.

generally, around here, we blame weird stuff like that on pugsy's aliens. the last time they were spotted, they were impersonating cats at pugsys place... eating her network cables.

The regular two hour cycles are quite common in REM sleep - that's how I started to figure out what's going on. Here's a thread I started a year ago:
viewtopic.php?t=94782
and another with more info:
viewtopic/t97878/Identifying-REM.html

Some people will claim you can't tell anything about REM sleep without eeg probes, etc, but for many people the breathing is enough. The only thing a bit unusual is waking more frequently than following REM sleep. Normally, after REM we partially wake up before the next cycle starts - this is what leads to regular bathroom breaks. If you're waking during NREM (the quiet period before REM) or in the middle of REM sleep, you're sleep patterns are possible disturbed.

You want up blow up what you're calling "REM"? You look like you have a lot of VT = 0 in there and REM tends to not do that.

Oh damn, maybe they're at my place . I sleep exactly like that, except that I wake up and usually have a night sweat (or hot flash, whatever ). Don't know about heart rate as I don't use an oximeter, but not really pounding.

Aliens seem like as good a cause as the next thing...

Care to elaborate Morbius?

What things make tidal volume tend towards 0?

And what does tidal volume tend to do in REM?

Inquiring minds want to know ....

Respiratory events. The VE and VT "variability" demonstrates a "pattern".

Well, right now we're still "inquiring".

Better yet, just upload the file to Dropbox, it'll be a lot easier than "post that", "enlarge this", "scale that", etc.

OTOH, based on previous posting, could be SWJ or BFM:

In reading through this thread I've noticed that no one has suggested the OP see a doctor, maybe rule out hidden cardiac issues if it hasn't been done - not wanting to worry anyone, but it's an old story that very many MI's take place first thing in the a.m. which signifies some 'timing' issue may be involved, OSA/Cpap or not. I see how easy it is to get carried away by the technology for so many of you and that's great, that you want to interpret and understand it all, but I wonder, considering the type of reports, etc. that are showing up here, whether it might be a good idea to ask an 'expert', i.e. doctor/cardiologist, what they think.

Totally agree with this Julie, especially when heart issues are involved, just to be on the safe side.

I give up, what's SWJ or BFM? And is that your chart, and what does it show?

What kind(s) of respiratory events?

What do VT and VE stand for? At first I though you were using VT for tidal volume, but I'm not so sure any more. Care to explain these acronyms for the rest of us?

Does VE = ventilation effort and if so, how are you measuring it from the charts?

Yes, we're still inquiring ...

But as always, your cryptic answers give us more to inquire about

more as a reminder of alternative ways to find stuff on the forum than anything else, going to google and searching this: site:cpaptalk.com swj would answer the first part of your question.

as to bfm? that's the first mention on the forum.

Hi, thanks for all the posts. I have been to a cardiologist and my heart is "normal", including an overnight halter test. They saw the speed up but my heart was working fine, according to them. So far they seem to think its most likely caused by anxiety possibly triggered by a sleep event. But I don't see the event and they happen so regularly. . I does look like I take a huge breath or gasp before waking up, but I'm no expert in reading this.

I will post a larger picture to dropbox and also a zoom later today (hopefully) when I get home. I honestly don't know what half the acronyms mean here, but I'll look them up.

Thanks guys!
