Thank you all!

I was just praising cpaptalk to the skies in another forum, and realized that a thank-you message to the folks here was way overdue. Pugsy in particular, and many other folks as well, were outstandingly patient, outstandingly knowledgeable, and just outstanding in general! Y'all got me through some ...

Re: Question about flow rate shapes

In through nose, out through mouth sounds like the perfect answer! It would also mean you keep "releasing" the pressure which could lead to events and a crappy feeling in the morning. Are you waking with a dry mouth? Is the water in your tank running out or very nearly running out? Do you use a chi...

Re: Question about flow rate shapes

yarrow, what mask do you have selected in the clinician's menu of the S9? Away from the machine right now, so can't check -- but I have looked in the past and believe it to be correct. Looking at the graph I think you have the wrong mask selected. Mathematically the area between the curve and the X...

Hmmmm... hadn't thought of that!

Re: Question about flow rate shapes

yarrow, how about changing the scale on the flow rate graphs to something like +/- 60 lpm to spread out the curve vertically. It'll give a better picture. It sure is an odd breathing pattern, to me anyway. SleepyHead seems to have a minimum scale (which varies day by day), that it won't let me go u...

Re: Question about flow rate shapes

Overall, the shape of your respiration waves show flatness on their tops instead of ideal rounded tops. It indicates some UARS (Upper Airway Resistance Syndrome). Most of SBD (Sleep Breathing Disorders) sufferers have it to some degree. The S9 Autoset machine analyzes the shape of the wave and give...

Question about flow rate shapes

I got about 9 hours of sleep last night -- very unrefreshing, alas. One thing I noticed was two half-hour periods with breaths like this: http://i1067.photobucket.com/albums/u431/yarrow-angelweed/CPAP/ShortBreaths.png where I seem to be breathing for a bit less than 2 seconds and pausing for a bit l...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Sorry about the RDI vs AHI boo boo. I just quickly glanced at that old thread where you mentioned it. That was my boo-boo, not yours -- I said AHI in the old thread. (I think I hadn't actually seen the study at that point, just got a number over the phone and assumed it was AHI.) You know if you ev...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Steroid Nasal sprays can cause insomnia as an FYI. When I experienced this with nasonex, I couldn't understand why. An RN I knew explained that the steroid part of the solution was causing the insomnia Thanks, 49er! I started the Dymista (azelastine and fluticasone) around the time things started f...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

what was your AHI originally? AHI 20.4 diagnosed per this thread. http://www.cpaptalk.com/viewtopic.php?f=1&t=78447&p=713492#p713492 You got it! Though looking back at the study, I didn't, quite. The diagnostic study RDI was 20.5, with an AHI of 14.1 and the rest RERAs. The titration study settled ...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Can you zoom in (like a 2 minute period) during a group of clustered events? I'd be curious to see what the flow chart looks like during those times. Here's a hypopnea: http://i1067.photobucket.com/albums/u431/yarrow-angelweed/CPAP/3-minHypopnea.png Two obstructives: http://i1067.photobucket.com/al...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Your FL graphs would be right up there with the coyote ugly ones. Particularly last night's! AHI up too. Not sure why. It was a short night because I had to get up early to do a system upgrade at work, but my events are not generally front-loaded. I did wake up on my back (from a dream). Interestin...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Your report at the top is showing EPR at 2... It reflects in EPAP and IPAP numbers...see the 2 cm difference. Yes, the doc apparently is fond of EPR. It hasn't been turned off on the 14th report unless you turned off after that date. For flow limitations usually a little more pressure...if you turn...

Re: Is ASV useful for AHI around 6, of which 4 are Centrals?

Have you ever tried cpap mode? Your flow limitation graph looks pretty ugly. Maybe those flow limitations are a factor in arousals????? Ah -- I've never known what the flow limitation meant, so mostly ignored it. Have you tried reducing or turning off EPR? Do you like EPR? Do you need the ramp? I m...
