Lung Volumes and Capacity

The formula for calculating Vital Capacity is (a)   using the given elements.

• IRV + TV + ERV

• VC - (TV + ERV)

• IRV + ERV + TV + RV

What is the formula for calculating Total Lung Capacity using the given elements?

Residual volume on a spirometer trace is _____.

Match the following lung volumes and capacities with their definitions.

• Tidal volume and vital capacity definitions.

• Tidal volume and vital capacity are defined as the amount of air breathed in and out during normal breathing, and the maximum amount of air that can be exhaled after a maximum inhalation, respectively.

• Expiratory reserve volume and inspiratory capacity definitions.

• Tidal volume is the maximum amount of air that can be inhaled after a maximum exhalation, and vital capacity is the amount of air breathed in and out during normal breathing.

• Inspiratory reserve volume and tidal volume definitions.

• Tidal volume is the amount of air breathed out during normal breathing, and vital capacity is the maximum amount of air that can be inhaled after a maximum exhalation.

• Residual volume and total lung capacity definitions.

• Tidal volume is the amount of air that remains in the lungs after a normal exhalation, and vital capacity is the amount of air that remains in the lungs after a maximum inhalation.

The formula for calculating Inspiratory Reserve Volume is (a)   using the given elements.

• IRV + TV + ERV

• VC - (TV + ERV)

• IRV + ERV + TV + RV
