[Diagnosis] Need Help Interpreting Daily Report

[achoden]

Hi, I'm somewhat new to this forum so please forgive me if I'm asking a question that's been asked many times before.

Here's my situation:
I have been using a CPAP for a little over a year now for mild OSA. My AHI averages about 3.5 and I sleep on the average of 7-8 hours per night. The problem is that recently I keep waking up two or three times during the night and have to take off the mask (AirFit nasal pillows) and put it back on until it's time for me to get up. With each awakening, I'm startled out of sleep and breathing quickly.

Could someone who knows how to interpret the Daily Report take a look at mine and give me some feedback? Also, I need instructions on locating and uploading the right data file. Thanks!

Sleepyhead creates a screenshot by simply pressing the F12 key, and stores it in My Document/Sleepyhead/Screenshots. You can attach that file using the forum attach image feature, or host the image on a site and post the link or image here. Here is a tutorial http://www.apneaboard.com/wiki/index.php...pnea_Board

Try to include the Events, Flow Rate, Pressure, and Snores or Flow limitations if available. On the left side of the daily details, minimize the calendar so we see more of the settings data.

Need 8 post for links. Attachment limited to 300KB.
Keeping that in mind, please do attach a screen shot.

Sleeprider is very good at deciphering. I'll give it a look too.

Okay. I uploaded a screenshot showing selected data from my Daily Report from Feb. 7.



I chose this report because it is atypical and weird (unusually low AHI, and amount of sleep time. Please take a look at the data and give me your impression (s) of any patterns you notice.

Thanks!

I'm not sure the atypical night is the one to analyze because that would be a poor choice for recommending any changes. You have exceptionally low AHI here and nothing remarkable in terms of events. You have a low tidal volume due to shallow breathing most of the night, and that seems to improve after 12:50. You might want to play with CFlex a little to see if a setting of 1 makes any difference. Keep in mind it doesn't affect the amount of pressure relief you get, just the timing of the change from exhale to inhale, with lower numbers providing a faster transition.

You have an unusual ratio of inhale time to exhale time 2.5:1.4. Most people have longer inspiration than expiration, and that ratio suggest possible airway resistance that might benefit from the pressure support of bilevel. However, this is as you said, an atypical night, and we don't know of any other medical complications or medication that might be going on.

I think you meant to say as marked above.

This is just one of the atypical nights I've been having. For the past few days I have been sleeping poorly, and tend to startle each time I awaken. One morning I woke up hyperventilating although I do not have any pulmonary problems that I know of.

Thanks for your interpretation. I think a change in the C-Flex is worth trying. All my neurologist keeps suggesting is to increase the pressure to 14, but we did that once and I could not tolerate it. I will discuss changing the C-Flex with him.

Hey JM! Someone has to proofread this stuff...you nailed it! Thanks
