Question

Respiratory volumes and capacity.

Answer 1

The vital capacity (VC) is the total exchangeable air in the system and is calculated by adding together tidal volume, inspiratory reserve volume, and expiratory reserve volume. Typically vital capacity is about4,800ml of air. The total lung capacity (TLC) is the total of all lung volumes and is about 6,000 ml.

Answer 2

respiratory volume :
1) tidal volume -5oo ml
i) dead air space -150 ml
ii) alveolar air - 350 ml
2) inspiratory reserve volume - 3000ml
3) inspiratory capacity -3500ml
4) expiratory reserve volume -1000ml
5) vital capacity - 4500ml
6)residual volume - 1500 ml
7)total lung capacity - 6000 ml.
