Usually, I put the mask on, adjust the pillows a bit, the machine kicks on, and I am good to go... I am a side sleeper, and I let the hose dangle down, and put a generous hose loop up and under the side of my pillow, and back to the machine.
(I have a smallish nose, and am using the small pillows. Also, like many people, one nostril is smaller than the other, and the smaller nostril is sore every morning.)
However, occasionally (like last night), I feel like the pillows have collapsed, and I get very little air. It seems no matter what I do, I cannot get the mask adjusted to provide proper airflow. As you would expect, when the mask is fitting like this, I fight the machine all night, and have bad numbers in the morning.. I cannot for the life of me figure out what I am doing wrong to make the mask behave in this manner...
