Solution:

Tidal volume (TV) is the volume of air inspired or expired during normal breath in each respiratory cycle without any effort. It is about 500 mL and is contributed by alveolar volume (350 mL) and dead space volume (150 mL).If TV = 500 mL and respiratory rate = 14 breaths per minute then, total tidal respiratory volume per minute= 500 x 14 = 7000 ml/min.
