Curious about constant pressure from oscar - jsl316 - 07-25-2023
*Warning, this may be a very dumb question
Oscar is showing constant pressure since changing settings of trigger --> very high. Prior to changing this setting, I saw fluctuation of pressure. I have attached two files of before and after adjustment
Is this normal? Currently trying out a new mask and was wondering if I needed to adjust my pressure. In context, I am changing from: p30i --> f30i
Thank you in advance!

That's because on April 13, you changed the pressure to mimic a static pressure.

If you add your PS (4) to the EPAP (6) it will be your maximum set pressure of 10. Your pressure can not go anywhere. The before had your max set to 20. This would allow your EPAP range to be 6 to 16, and your IPAP to be 10 to 20. Also, please use the Fn+F12 key to take the screenshot. We need to see your data and not the calendar.

So would it be advisable to go back to my previous settings to see the pressure difference while I try out the F30i?
As a cpap newbie, I'm still confused how aircurve 10 works. Does this machine adjust accordingly if I leave it to max settings? Or is it better to have a static pressure as I have been using the past couple of months?
Sorry for the endless questions
RE: Curious about constant pressure from oscar - Crimson Nape - 07-25-2023
It will adjust based on your flow limitation. The drawback of having a large upper limit is a disturbed sleep from excessive pressure changes. Looking at your variable settings, I would try setting the EPAP at 7, IPAP at 13, and leave the PS at 4. This setting allows for a 2 cm variance, which should reduce the possibility of a pressure disturbance. You can always fine tune from there, if needed.

Thank you soooo much for your assistance! I'm excited to try out the new settings tonight.

@crimson nape,
Any suggestions if I should change my pressure settings?
For reference:
AHI 5.14 + 2.4 (7-13 pressure setting)
AHI 1.57 (6-10 pressure setting. First night trying out new mask (F30i))

Notice that the events are in clusters, and not spread out. This indicates that this is positionality induced. You are either chin tucking, and/or sleeping on your back.
For chin tucking, you can try a Soft Cervical Collar (SCC) to help prevent this. See the Wiki article on SCCs (https://www.apneaboard.com/wiki/index.php/Soft_Cervical_Collar) for more information. Depending on your pillow type, you can also try positioning a corner under your chin to keep from tucking too.
For back sleeping, there are several avenues to address this. They range from body pillows to tennis balls attached to the back of your sleeping shirt.

Thank you soo much for your wisdom and knowledge. I had no idea that the cluster of OA could be due to positional apnea!
But I'm super grateful for helping me!
