Q14   What is Tidal volume? Find out the Tidal volume (approximate value) for a healthy human in an hour.

 

Answers (1)

Tidal volume is the volume of air that is transported into and out of the lungs (inspired or expired) with each normal respiratory cycle. Tidal volume is approximately 6000 to 8000 mL of air per minute for a healthy human.

We can calculate the hourly tidal volume for a healthy human.

If, Tidal volume = 6000 to 8000 mL/minute

So, the Tidal volume in an hour will be:

= 6000 to 8000 mL × (60 min)

= 3.6 × 105 mL to 4.8 × 105 mL

Hence, the hourly tidal volume for a healthy human is approximately 360000 ml-480000 ml.
