headache caused by CPAP?

I have a massive headache today after night one on the CPAP, is that a coincidence or can that be caused by getting used to the machine?

Do you know at what pressure range you auto is set? What is the minimum pressure and the maximium?

If the minimum pressure is set too low (4 or 5 cm) then it could well be the reason for your headache. It may be too low to adequaely blow out the CO2 in your mask so are rebreathing some of it. That can cause a headache!

It may also be that you have the headgear straps on your mask too tight. That could do it as well.

I think the setting is at 10. I also agree that I probably had the straps done up too tight. I really tightened them through the night. I will loosen everything up tonight and see how it works. thanks and yes I am happy that i have started CPAP...

My headaches have stopped since I started CPAP.

The mirage quatro works better when it is looser. It inflates when the pressure starts and if it is too tight it can't so it leaks.

One night is not really a test either.

I got pretty much of an immediate headache at the titration study caused by the lower straps hurting my cervical spine when the tech tried me on a nasal mask first thing.

So the straps being too tight could definitely be the culprit.

I had headaches before CPAP and for the first couple weeks once I started CPAP. Headaches have pretty much disappeared now.

Given that your setting appears certainly high enough to not be the culprit, I think is is more likely that the straps on your headgear are too tight and causing the headache.

Good luck with them a looser tonight.

I just started using the machine a week ago. The first few days, I would get tension headaches. It felt like all the muscles in my head were tensing up in response to having this thing strapped to my head. I have had to really practice hard at keeping my face and scalp relaxed while wearing the mask. But it has helped.
