Tidal volume is defined as the volume of air inspired or expired during normal respiration.
It is about 6000 to 8000 mL of air per minute.
The tidal volume in an hour 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 × 105 mL to 4.8 × 105 mL
Thus, the tidal volume in an hour for a healthy human is approximately 3.6 × 105 mL to 4.8 × 105 mL.
