What kind of testing did everyone get? I have a bad cough going on and i hope i do okay!

I had some breathing tests where I sat in a clear enclosure with a mask and had to breathe in and out or hold my breath when the tech signaled. . Nothing hard or invasive. No treadmills (thank God) and nothing painful. My sleep study was also part of the pulmonary clearance. I actually had two sleep studies - one without a CPAP and one with a CPAP.
