Those kind of side effects can happen during the Tensilon test. They only like to do it in a hospital setting these days due to reactions people can have.

What I'm curious about is what your O2 is while you're sleeping. Mine was 94-95% on the 3rd day in the hospital but my sleeping O2 dropped down to 66%. My O2 during my crisis was initially dipping into the 70's while awake. They did 2 ABG's. Sometimes they wait until it gets to 88% or below before they do an ABG.

If you get a pulmonologist, ask if they can do an overnight oximetry. They send you home with the machine and then you bring it back the next day.

ABG's can be useful but your docs are taking a more clinical approach. No bonking heads! You are getting good care and just work with them.

I'm glad you've got someone to look out for you!
