hi guys! my name is mark. im 35 yrs old. 3 yrs ago i had pneumothorax(collapsed lung) and my doctor told me that i have emphsyema. like everyone else here, i am also very much concerned abt life expectancy when u have this kind of disease. i get chest pains most of the time and have anxiety attacks. last week was my first time to try spirometry. i would like to ask if the fev1 is different from the fev1/fvc?
my fev1/fvc is 76%. dont know where to locate my fev1. im not sure if this is the one it says pre-rx %pred 94? im not sure if the 94 is my fev1.
