Have to go get one in a few hours. I'm a little nervous about it. I think because I get conflicting info online, and don't know of anyone who has had this done. Any info would be great. Thanks

Oh gosh, I can think of about 8 things off the top of my head called "PST test" and none of them are the same thing - though more than one ofthem could apply to this surgery. Can you give more info?

It is a pulmonary test. For lung function.

it's actually a PFT = Pulmonary function test. They aren't bad. You breathe into a tube while the technician tells you what to do. Usually they cheer for you ... blow blow blow ...deep breath in...yelling the whole time. LOL

I do them for asthma once a year. It measures how much air you take in versus how much air you expel when you breathe out.

non-invasive and pain free.

Thank you!

Pain free if you don't get an excruciating headache afterwards ( I get them BAD)
