#### Question

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

#### Solution

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
