What is the total volume of air, including the tidal volume and inspiratory reserve volume, that a healthy adult can inhale during a deep inspiration?
3500 mL to 4000 mL
4000 mL to 4500 mL
4500 mL to 5000 mL
5000 mL to 5500 mL
The total amount of air that can be inspired by a healthy adult during a deep inspiration, including the tidal volume and inspiratory reserve volume, ranges from 2500 mL to 3000 mL (IRV) plus 500 mL (TV), which is 3000 mL to 3500 mL. Adding this to the average tidal volume of 500 mL gives a range of 3500 mL to 4000 mL
Option 1 is the correct answer.
