Question

Using the formula Tidal volume (Vt) - Dead Space volume (Vd) × respiratory rate = minute volume (Vm), the result is known as:

A) Inspiratory Reserve Volume (IRV)
B) Expiratory Reserve Volume (ERV)
C) Alveolar Minute Volume (AMV)
D) Total Lung Capacity (TLC)

Answer 1

The formula Tidal volume (Vt) - Dead Space volume (Vd) × respiratory rate = minute volume (Vm) calculates the Alveolar Minute Volume (AMV).

Step-by-step explanation:

Tidal volume (TV) is the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters. Expiratory reserve volume (ERV) is the amount of air you can forcefully exhale past a normal tidal expiration. Inspiratory reserve volume (IRV) is produced by a deep inhalation, past a tidal inspiration. Residual volume (RV) is the air left in the lungs if you exhale as much air as possible.

The formula given, Tidal volume (Vt) - Dead Space volume (Vd) × respiratory rate = minute volume (Vm), calculates the minute volume of air that is being moved in and out of the lung in one minute. This minute volume is also known as the Alveolar Minute Volume (AMV), hence the correct answer is C) Alveolar Minute Volume (AMV).
