Oh goody...received an appointment today for a lung function test...not 'til February though so it's a while away yet. The letter said to not use any breathing meds for twelve hours beforehand...they have to be joking. If I didn't, I'd be dead or comatose. Then how far would I get in the lung function tests I ask myself...a zero score would be likely.
They shut you in a sort of transparent phone booth and feck about with the oxygen levels while bawling instructions to 'Breathe!' through an intercom...
All the results come out via a computer...reams and reams of paper covered in little squiggles...when I had one such test a couple of years ago, I asked the technical bod who operates the various machines what my score was...she answered in one word.
