Just to share my experience....
I received my BiPAP unit a few weeks before my first pulmonologist appointment. The initial settings were made by the RT who provided the equipment. To change the settings on my machine, the pulmonologist’s office has to fax orders to the equipment provider, and then the equipment provider changes the settings remotely.
After I saw the pulmonologist, she increased the IPAP to a ridiculously high level, to “decrease my work of breathing.”
Well I did not tolerate that big increase in pressure at all. My ear drums were popping with each inspiration. This occurred on a Thursday night, and the pulmonologist was off that Friday, so it wasn’t until Monday that I could get the settings changed. I went 4 nights without using the machine.
Subsequently, our Laurie ran me through how to change the settings. I made a few very minor tweaks which improved my comfort using the machine. I explained later to the Pulmonologist the changes I had made, why I made them, and that I wanted to work with her going forward. She seemed fine with that.
So I think it is important to at least know how to adjust your own settings. That was my experience. Your mileage may vary....
