What is Tidal Volume (TV)?
What is Tidal Volume (TV)?
Options
- AVolume of air inspired or expired during a normal respiration
- BVolume of air inspired during a deep inspiration
- CVolume of air expired during a deep expiration
- DVolume of air inspired or expired during a forceful respiration
Correct answer
A. Volume of air inspired or expired during a normal respiration
Step-by-step solution
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.
