Q.14:- What is Tidal volume? Find out the Tidal volume (approximate value) for a healthy human in an hour.
Tidal Volume (TV): The volume of air inspired or expired during a normal respiration is called Tidal Volume. It is approximately 500 ml in a healthy man. This means that a healthy adult can inspire or expire about 6 to 8 litre of air per minute.
Tidal Volume = 500 ml
Respiration rate = 12 per minute
Hence, Tidal Volume in 1 hour = 500 ml x 12 x 60 minute = 360000 ml = 360 litre
