Spirometry

Question 1

Tiffaneau Index

Answer 1

FEV1/FVC (%)
>70-80 = Normal or Restrictive
<70 = Obstructive

Question 2

Dynamic lung volumes

Answer 2

Related to rate at which air flows in/out of lungs

Question 3

Static lung volumes

Answer 3

Not affected by the rate of air in/out of lungs

Question 4

Tidal Volume (TV)

Answer 4

500 ml
Amount of air entering/leaving the lungs without extra effort

Question 5

Inspiratory Reserve Volume (IRV)

Answer 5

3100 ml (1900 ml F)
Max inspiration above tidal volume

Question 6

Expiratory Reserve Volume (ERV)

Answer 6

1200 ml (800 ml F)
Volume exhaled above tidal volume

Question 7

Residual Volume (RV)

Answer 7

1200 ml (1000 ml F)
Air remaining in the lungs after complete exhalation

Question 8

Inspiratory Capacity (IC)

Answer 8

3600ml (2400 ml F)
Largest amount that can be inhaled
(TV+IRV)

Question 9

Functional Residual Capacity (FRC)

Answer 9

2400 ml (1800 ml F)
Volume after normal expiration

Question 10

Vital Capacity (VC)

Answer 10

4800 ml (3200 ml F)
Entire volume that can be maximally inhaled and exhaled

Question 11

Total Lung capacity (TLC)

Answer 11

6000 ml (4200 ml F)
All of the lung volume
(VC + RV)
