Hi everyone, My husband has been diagnosed with obstructive apnea (mild to moderate) and had his first night with his CPAP last night (Philips respiratonics (?)). He’s been complaining of headaches today, as well as aerophagia. Is this normal? When searching through the web, it says it might be because of a too high pressure, but his CPAP is auto-adjusting the pressure (started the night at 5, and it went up to 10). Is there something he can do ? Are the headaches normal for first-time users? Thank you!
