1

"In and out like the tide"

Volume inspired and expired with each breath at rest

- 500ml in males

- 350ml in females

Tidal Volume (TV)

2

"Maximum, inspired, normal"

Maximum volume of air that can be inspired at the end of a normal tidal inspiration

Inspiratory Reserve Vol (IRV)

3

TV + IVR

Inspiratory Capacity (IC)

4

"Maximum, expired, normal"

Maximum volume of air that can be expired at the end of a normal tidal inspiration

Expiratory Reserve Volume (ERV)

5

"It resides so it remains" - it gets minimal EXposure

Volume of air remaining after minimal expiration

Increases with age

Residual volume (RV)

6

= ERV + RV

= 2.2L in a young man

Functional Residual Capacity

7

"Maximum, expired, maximum" 2 maximums, so its vital

Maximum volume of air that can be expired after maximum inspiration

= IC + ERV

Decreases with age

- 4500ml in males

- 3500ml in females

Vital Capacity (VC)

8

= VC + RV

Total Lung Capacity

8

= TV x ((PaCO2 - PeCO2) / PaCO2)

Physiological Dead Space
