My history is that I had severe apnea 20 years ago but had to stop wearing a mask because of sinus blockage and full face masks did not exist then. A recent sleep study gave an AHI of 54 and I am now trialling masks with a retailer. Data from Philips is discussed and passed on to me.
To me it seems that one of the most important records would be spO2 levels but the Philips data does not give this.
The reason I have come back to CPAP is because of strong warnings about damage to organs including the brain and heart.
I am at a loss to understand why more importance is not given to spO2 levels given the above. I bought a recorder with spO2 assistant before treatment and my graphs have gone from jagged lines extending to the low 70s and even a low 64 to a fairly level line above 90. I now use Sleepyhead data also when assessing the success of masks but spO2 seems the more useful tool.
Apologies for the length of this but are my thoughts way off base?
