Help with Interpreting OSCAR Data - chillzap21 - 11-18-2021

I have been using Airsense 10 for quite a while. However, I have recently been struggling with the therapy. Please take a look at the screenshots and let me know what I am doing wrong and how the results are looking in general.

Additional screenshots for reference.

Welcome to Apnea Board,

First thing to address is the leaks. Look at your leak chart. Find the spikey pattern, this signifies the mask is leaking. The majority though, the flatter rounded leak pattern, this is going to be mouth leaks. Combined they've blown your therapy. The PAP can't effectively or accurately give good therapy during this session.

You're probably aware, the ResMed leak redline is 24 and you were at 30 or so most of the night.

Thank you very much for your response. 

I'm not sure why there was so much leaking last night. I cleaned everything yesterday, so I was hoping for an improvement. 

I have attached my leak chart from two nights ago, does that look fine?


RE: Help with Interpreting OSCAR Data - SarcasticDave94 - 11-18-2021

It's better than the first chart, but it's not the greatest.

Since you just cleaned your mask, disconnect and try a reassembly. Maybe something didn't click into place correctly.


RE: Help with Interpreting OSCAR Data - chillzap21 - 11-18-2021

As per your suggestion, I reassembled all the parts that I had cleaned, and I am attaching the results from last night for the same.

In the leak chart, there is an indication of large leaks in the first hour, but it seems pretty okay after that. What could be the possible reasons for the same?

Also, are there any other observations from the charts in general? Thanks in advance.

My 2cents for what is worth is your high pressure is 20. My mask would blow also. You have run away pressure caused by flow limits. 

I can give 3 ways to try to handle the pressure

1. Limit the high (max) pressure. You might try a max of 15 and see how that does for control of apnea and keeping the mask on. If to high still try 12. 

Or

2 raise the min to 8 and EPR to 3. 

Or

Combine these

Max 15, min 8, EPR 3

I’m not sure which will be the best for you.


RE: Help with Interpreting OSCAR Data - Melman - 11-18-2021

It appears you are not using EPR. I suggest you set EPR full time at 3. That should reduce your flow limitations and probably lower the high pressure excursions. I agree with Stacey that the flow limitations are driving the pressure. Also increase the minimum pressure to at least 7 to get the maximum benefit from EPR. A max pressure of 15 should not be too much for the F20. I use the F20 at a maximum of 14 with no leak problems. One issue I've had with the F20 is large leaks caused by my jaw dropping and my lower lip breaking the seal. I've found that a soft cervical collar prevents that. Be sure to post data again after making the changes.


RE: Help with Interpreting OSCAR Data - chillzap21 - 11-19-2021

Thanks a lot to both of you. Will make these changes in the settings and post the OSCAR results after that.


RE: Help with Interpreting OSCAR Data - chillzap21 - 11-19-2021

Here are the results after making these changes. While the leaks seem to have improved quite a bit, the AHI is actually higher. What are your observations from these results?

RE: Help with Interpreting OSCAR Data - staceyburke - 11-20-2021

The night did look better.  But your flow limits are still quite high.  EPR is set as high as it can go, so I would move the min up .5 to 8.5 and see if that controls them better.  Your high was controlled and it looks like your leaks were helped.  Give it a night and try to be honest with "how do you feel" - better - Worse....?  Don't look an any numbers just how do you feel?

Please post the nights oscar just the first page is enough.
