need help with data

Ok I got my software today and downloaded my data. I wondered if anyone could help me interpret it. i am not familiar with the term run and wonder if the high number is something I should be concerned about and what I can do to inprove it. Here is my data:

average pressure 8.2 with the low (ramp) .4 and high 10

analysis period 22 hours 52 minutes

apneas; 15

apneas with cardiac oscill; 4

Hpopneas 8

flow limited hypopneas 0

vibrations 22

flow limitations-runs 123

leaks range from ,4 to,6 at teraputic pressures of 8-10 cmH2O

thanks! -Magpie

I did n't give the index/ hour for this so here it is:


number Index/h

apneas; 15 = 0.7

apneas with cardiac oscill; 4 = 0.2

Hpopneas 8 = 0.3

flow limited hypopneas 0 = 0.0

vibrations 22 = 1.0

flow limitations-runs 123 = 5.4

good gosh I spaced everything out in neat columns and this is how it posted. I'm sorry, hope you can make it out.

The forum software drops normal spaces... It cathes all of us unawares the first (and second) time.

Your doing great, numberwise, magpie, and I wouldn'd worry about the "flow limitation runs". They're defined in the manual as a consecutive number of flow limitations - I don't believe there's any standard for them. With all your other results indicating such good therapy, I wouldn't attempt any changes.

If you're feeling like your data looks, you must be having a great time!

(And if you want to insert spaces and have them stick, like     this, press ALT and then 255 on the number pad - it's a hard space that the software doesn't drop.)

Congratulations!

Thank you Ozij. Unfortunately I am not feeling like you say I should. I guess I just have a huge sleep deprivation to make up for. Also, I wake up alot during the night and my sleep latency is 16 so my sleep is still very disturbed. I am guessing my body is still going into panic mode when my breathing is interupted. Hopefully things will improve with time.

magpie,
I wasn't paying attention to your pressure range. You write average pressure 8.2 with the low (ramp) .4 and high 10 If both your lowest ramp pressure and your bottom pressure is 4, then your range is pretty wide, and you may be waking up from the pressure changes, and not from your breathing interuptions. With an average of 8.2 you're spending most of you time in the high part of the range in any case.

Is this "leaks range from ,4 to,6 at theraputic pressures of 8-10 cmH2O"
you, speaking or the software?

If your range is 4-10, and the software is identifying a therapeutic range of 8-10, then I would definitely raise the bottom value - I'ld have it at least at 6, and woudl try raising it gradually to 8. Or is your range 8-10?


How are you doing for mask comfort? Noise?

Can you post a screen shot of the details screen?
O.

Ozij, My range is set at 8-10. The ramp is set to start at 4 and builds over 20 minutes.

Recorded pressuer as per software is low = .4 Average = 8.2 and high = 10.0

as mentioned by ozij, your numbers look very good. The only difference between a flow limitation and hypopnea is the amount of obstruction and the duration. You might look at Flow limitation as the start or beginning of a Hypopnea or change from normal airway patentcy to restricted airway where if it becomes greater than 50% and/or lasts longer than 10 seconds where they may become a hypopnea, but not all FL's turn into Hypopnea.

That machine will use less than 50% criteria for determining a hypopnea (it may use 40% for example vs. 50% used in a lab), but it doesn't really matter the machine will handle what it sees automatically.

Your numbers look good, I wouldn't worry about it or make any changes it appears to be doing a good job.

You might want to look at the 96 hour detailed data report, those apnea with cardiac oscillations, those can be a indicator of central apnea seen by the machine (2nd line of that report). If they appear within the first 30 minutes of falling asleep they may be considered sleep onset events, if they appear after a apnea later in the timeline they may be post-arousal centrals and/or if they align with a apnea they may be mixed apnea. You would have to refer back to your PSG and see if they were also present there, but from your data there is nothing to worry about.

Snoredog, Moy centrals were present during my PSG. They were considered to be of short duration and therefore have not been addressed.
I do not have the charts from the study only the report so i cannot tell you for certain when they occured that night. From the new data i took off my machine this morning most of the respirtory events appear to occur around the 4th hour of sleep.
