Final answer:
The amount of air moved through the respiratory tract, including the anatomic dead space, in 1 min is known as the minute ventilation. It is calculated by multiplying the tidal volume by the respiratory rate.
Step-by-step explanation:
The amount of air moved through the respiratory tract, including the anatomic dead space, in 1 min is known as the minute ventilation. It represents the total volume of air entering or leaving the lungs per minute. It is calculated by multiplying the tidal volume (the amount of air inhaled or exhaled in one breath) by the respiratory rate (the number of breaths per minute).
For example, if the tidal volume is 500 mL and the respiratory rate is 12 breaths per minute, the minute ventilation would be 6,000 mL per minute (500 mL x 12 breaths).
Therefore, the minute ventilation takes into account both the amount of air moved during each breath and how frequently the breaths occur.
