[Diagnosis] New to Boards and Data

[mikevyo]

Hi everyone. New to the board. I've been using Cpap for OA for 6 years now. I finally was able to get insurance to provide me with the airsense 10 auto, so I can finally view data. Upon looking at my data, ive noticed that my Resp rate has been high every night. Also my AHI has been very low, but when i scroll throigh my flow rate, i see many events where i appear to not breath for 9 seconds. I have attached some screen shots. Also my resting RR while awake seems to be 15. I can tell when i fall asleep because it just right to 20.

First two pics are events my machine didnt pick up. Last one is the only flagged event. They also seem to correlate with leaks. The other pic is zoomed out of whole night

At 5-20 pressure, EPR 2, your results look good, and the respiration rate is not something you should worry about, and not much you can do about it anyway. The higher respiration rate and good tidal volume results in a very good minute vent. I think there is some flow limitation, and I'd like to see you minimum pressure at 6.0. With EPR 2, that gives you a starting pressure of 6.0/4.0 and will stay more constant. If you want to try more EPR for flow limitation, the a minimum pressure of 7.0 with EPR 3, will give you 7.0/4.0 and should eliminate most of the flow limitation we're seeing in the close-ups. The additional per-breath volume (Vt) may slightly decrease the respiration rate, but I wouldn't make any promises. People tend to breathe at a comfortable rate when sleeping, and there is nothing exceptional about 20 BPM.

Thank you for the reply. I will try the suggested settings tonight. Which do you think I should try first, 6 min pressure and EPR 2, or EPR 3 and 7 min pressure. I’m still not quite sure I understand flow limitation yet, and I’m currently looking into it.

Would you mind explaining what tidal volume is.  I have looked and can't seem to find anything.  

Thanks.

besides an internet search there are at least 3 ways (and probably more) to get a brief definition for some things in oscar.

there's a 'sleep disorder terms glossary' at top left under 'help'

hover your cursor over the left side of the relevant graph on the 'daily' tab, between the title and the left vertical box line

hover your cursor over the relevant title at far left of the statistics box on left side of 'daily' tab.

I'm pretty sure there are more detailed explanations of terms in the wiki (click on same in menu bar at top of this page) but someone else will have to point you to the exact locations.

...when i scroll throigh my flow rate, i see many events where i appear to not breath for 9 seconds.

Events less than 10 seconds are not considered to be events so the machine doesn't flag them They have to draw a line somewhere and 10 seconds is a reasonable number.

SleepyHead and Oscar have a facility to flag events of greater or lesser duration. Go to File | Preferences | CPAP and turn on Custom cpap user event flagging. You can then set the machine to flag events of eg 5 and 9 seconds. It takes a few minutes to recalculate - longer if you have many years of data. There's no indication that anything is happening so you might think SleepyHead has crashed - just be patient.
