I had my first test and told I have 5.6% lung function, devastated of course and still dazed. I can't understand how one can actually blow into this spirometry when your mouth is wide open it was so big so I am blowing from the back of my throat, is this normal for everyone? It was cardboard and I live in Cyprus. Is it me but how can you blow properly if your mouth is so wide open? Is this normal.?
