ResMed AirSense 10 AutoSet question

Diagnosed with OSA in 2017. Have used the Airsense 10 every night for 3 years and take good care of it. Full F20 mask with heated hose. AHI "Events" has always been between 0 and 5. All of a sudden, for 8 straight days now, my AHI "Events" are in the 30's and 40's. Would someone advise me what I am supposed to do? Very strange to me how my events have just "spiked". Do I need a pressure adjustment or perhaps a new machine? Help!

What is that AHI composed of?

Do you know about available software to see what that AHI is composed of?

More pressure might be needed if the AHI is primarily obstructive in nature.
More pressure won't help if the AHI is primarily central (clear airway) in nature.

More importantly I would be wondering what changed to cause just a marked difference. Meds, leaks, whatever????
