Do you have the prongs or the nasal pillows? When I was tested my pulmonologist was pretty sure it was going to come back positive (long story but I'm allergic to tetanus shots and while they tried giving them in half doses I did not get immunity to pertussis. There was an outbreak when I worked in home health and even though work took precautions to protect me I caught it anyway from someone who I knew later was misdiagnosed (I'd never heard the cough before nor had most people I worked with so while she had a terrible cough it just was assumed to be her way of coughing). So I had full-blown pertussis at 35 years old. I wound up with asthma and chemical sensitivities so that anything can trigger asthma attacks although now that I'm not working in poorly cared for homes it is much better. But my pulmonologist was hoping that some of my sx added up to apnea due to the lung damage and he thought it would help the bipolar as well.

I was really concerned about the Cpap and didn't want to do the study because I knew I wouldn't sleep with it but he showed me this alternative to the things up your nose called pillows that rest on your lip and just touch your nose. He said they'd be much more comfortable/gentler and that it would improve my sleep so much that I wouldn't mind them. They didn't feel like much that was bad so I agreed to the study. I have mild apnea that doesn't qualify for Cpap but I did remember the pillows vs. prongs for the future.
