Don’t know whether any of you out there have experienced this one but it was quite quite a surprise. It’s part of a set of cardio-respiratory tests to test lung efficiency. You are put into a sort of gas chamber, or that is what it feels and looks like, and you pop your mouth into a breathing device with your nose crimped. The chamber is sort of sealed and and you are instructed to breath normally (fat chance) then to pant and then the thing you are breathing through is sealed off but you have to continue to make the muscular movements of panting. I have made it sound worse than it is, you are not in an airless chamber and you have an escape button but I am buggered if I could do it. Oh and the other thing is you must not move your cheeks. Anyway it reminded me of dance classes I had in the 80’s which required the isolation of certain parts of the body, something like moving your elbow without moving your shoulder – useful training if you plan to audition for ‘Cats.’ Needless to say I just couldn’t do it and became quite giggly-naughty once the fear of suffocation had abated. This test was followed by another test in which you are required to breath in Carbon Monoxide – again presented in the way it was this sounded like voluntary euthanasia, not particularly dispelled by the comment ‘you might feel a bit woozy.’ Anyway I think I passed that one. Another happy day at the hospital.
