What is the average Tidal Volume (TV) in healthy adults?

Options

  1. A500 mL
  2. B1000 mL
  3. C1500 mL
  4. D2000 mL

Correct answer

A. 500 mL

Step-by-step solution

The average Tidal Volume (TV): Volume of air inspired or expired during a normal respiration . It is approx. 500 mL., i.e., a healthy man can inspire or expire approximately 6000 to 8000 mL of air per minute. Inspiratory Reserve Volume (IRV): Additional volume of air, a person can inspire by a forcible inspiration. This averages 2500 mL to 3000 mL. Expiratory Reserve Volume (ERV): Additional volume of air, a person can expire by a forcible expiration. This averages 1000 mL to 1100 mL.
