Question

What is Tidal volume? Find out the Tidal volume (approximate value) for a healthy human in an hour.

Answer 1

Tidal volume is the volume of air inspired or expired during normal respiration. It is about 6000 to 8000 mL of air per minute.
The hourly tidal volume for a healthy human can be calculated as:

Tidal volume = 6000 to 8000 mL/minute
Tidal volume in an hour = 6000 to 8000 mL × (60 min)
= 3.6 × ${10}^5$ mL to 4.8 × ${10}^5$ mL

Therefore, the hourly tidal volume for a healthy human is approximately 3.6 × ${10}^5$ mL to 4.8 × ${10}^5$ mL.
