Morning everyone. Yesterday I did a lung function test at my local chemist. Neither she or I knew if we were doing it right. The way we did it was to breath hard but for as long as I could. I have since been told that what you are supposed to do is to breath out as fast and hard as possible rather than just consistently blow hard. Does anyone know what the answer is?
To be honest it scared the hell out of me. I am 38 and the result suggested I have the lungs of a 52 year old- even though I am a light smoker and do loads of exercise. The chemist thought we had done it wrong, but I don't know. Help!
