Is 5,000 good or bad?
You've done an exercise to measure your vital capacity, or the total volume of air that can be moved in and out of your lungs.
Vital capacity depends largely on your body type; larger people have large VC's. I used to know a simple rule of thumb for predicting VC from bodyweight, but I've forgotten the exact conversion. IIRC, 5000 cc is about normal for a person 5'8"-5'10", 160-220 lbs. You might be concerned if you taller than 6'4".
VC values significanlty lower than normal are indicative of respiratory disease, such as asthma or emphysema.
