Calculate the inspiratory capacity given the following information Tidalvolume = 500 mls, vital capacity = 5000mls expiratory reserve volume =1,000 m/s

Question

6,500 mls 4,000 mls
500 mls
3.500 mls
1,500 mls

Answer 1

The inspiratory capacity can be calculated by adding the tidal volume (500 mls) and the inspiratory reserve volume, which can be found by subtracting the expiratory reserve volume (1000 mls) from the vital capacity (5000 mls):

Inspiratory reserve volume = Vital capacity - Expiratory reserve volume
Inspiratory reserve volume = 5000 mls - 1000 mls
Inspiratory reserve volume = 4000 mls

Inspiratory capacity = Tidal volume + Inspiratory reserve volume
Inspiratory capacity = 500 mls + 4000 mls
Inspiratory capacity = 4500 mls

Therefore, the inspiratory capacity is 4500 mls.
