Question

Distinguish between inspiratory capacity and expiratory capacity.

Distinguish Between

Solution

 

Inspiratory capacity (IC)

Expiratory capacity (EC)

1. It is the amount of air that is suitable for inhalation following a typical expiration. It is the amount of air that is expelled following a typical inspiration.
2.

Tidal volume and inspiratory reserve volume are included.
IC = TV + IRV

Tidal volume and expiratory reserve volume are included.
EC = TV + ERV

3.

It is about 3000 to 3500 mL of air

It is about 1500 to 1600 mL of air
