Question

multiple choice question
define minute ventilation.
-
o amount of air moved into airways per minute
o amount of air remaining in trachea and bronchi per breath
o amount of air available for gas exchange per minute
o amount of air moved into alveoli per minute

Explanation:

Minute ventilation is defined as the total volume of air that moves into the airways (including the trachea, bronchi, etc.) in one minute. It is calculated as the product of tidal volume (volume of air per breath) and respiratory rate (breaths per minute). The option "amount of air remaining in trachea and bronchi per breath" refers to anatomical dead - space volume per breath. The option "amount of air available for gas exchange per minute" is alveolar ventilation (which subtracts the dead - space ventilation from minute ventilation). The option "amount of air moved into alveoli per minute" is also related to alveolar ventilation.

Answer:

amount of air moved into airways per minute
