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...

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?

I got my CPAP on a 30 day trial yesterday and have gone through my first night with success. I woke a few times to adjust the mask and this am i am red on the bridge of my nose. Does it usually take a few days to get the mask fitting properly? I am still extremely tired and hoping that changes soon....
