What mask are you using? I was using mirrage quatro but switched to an airfit 10 and started having peobl Ms you describe si bad I went back to original mask and qm bow getting scores between 96-100!
The newer cpap/bipap machines have a built in humidifier to prevent dryness.
I am on oxygen but use only my bipap at night. Was using oxygen initially with my cpap/bipap. You may want to discuss this w your sleep doctor as if needed there is a small plastic connector that can be used to bleed oxygen n into sleep equipment if needed.
