Question

A spirometer lung capacity and volume. WHy are these measurements important.

Answer 1

Because it tells you how much air you can breath in and out of your lungs. If you have emphysema, you will be able to take in a normal volume of air, however, during exhalation the volume of air you breath out will be too low. So such measurements can tell you if your patient has a disease related to inspiration or expiration or both.

Answer 2

this is important for diagnosis of lung/respiratory disorders.
only when u know how much a air a person breathes normally u can detect if hes breathing less!
