spirometry

Question 1

inspiratory reserve volume IRV

Answer 1

• maximum volume above tidal volume that a patient can inspire

Question 2

tidal volume (Vt)

Answer 2

• volume of inspiration and expiration during restful breathing

Question 3

ERV, expiratory reserve volume

Answer 3

• maximum volume below tidal volume that patient can expire

Question 4

residual volume RV

Answer 4

• volume of air remaining in lungs after full expiration

Question 5

inspiratory capacity

Answer 5

• all air breathed in during maximal inspiration at the end of normal expiration

Question 6

expiratory capacity

Answer 6

This is all the air breathed out in a maximal expiration after a normal inspiration. It is calculated by VT + ERV.

Question 7

funcitonal residual capacity

Answer 7

This is the volume of air remaining in the lungs at the end of a normal expiration. It is calculated by ERV + RV [+].

Question 8

vital capacity VC

Answer 8

This is all the air that can be expired from a maximal inspiration. It is calculated by IRV + VT + ERV.

Question 9

total lung capacity

Answer 9

This is all the air that it is possible for the lungs to contain. It is calculated by IRV + VT + ERV + RV.

Question 10

forced vital capacity FVC

Answer 10

This is the maximum volume of air that a person can forcibly expire after a maximal inspiration [+].

Question 11

forced expiratory volume in one second FEV1

Answer 11

This volume is known as the forced expiratory volume in one second
