Is Pressure Set incorrect?

[rberry1]

Hello
I am new to OSCAR.  I have a ResMed device and so far I understand OSCAR for that device.  However, I also use a Philips Dreamstation and do not understand pressure tracings in OSCAR.   I have looked at numerous forum threads but still do not
understand.  Sometimes Pressure set seems to be the treatment pressure and EPAP is lower using Aflex as expected.

However, I attach a tracing that is completely confusing.  Although the Pmax for APAP is 8 cm H2O the pressure set is 8.7 cm H2O.
Later in the study it is even higher (over 9).   If pressure set is really the delivered pressure how can it be higher than the maximum pressure.   I am missing something here.  Please help.

Since this is therapy related, I will be moving it to the Main Forum after my post.

While it shows you have a maximum pressure of 8cm, the details show your machine went to 10cm. You have the Flex set to 3. This is known to make the Philips go off into the weeds. For this reason, the max flex should never exceed 2. It is not like the Resmed EPR. Close, but no horseshoe. Another explanation could be a defective pressure sensor.

I think the pressure sensor is not working. I have used Aflex 3 for years without an issue. Thanks for the reply rb
