Question

After performing a pulmonary function test, Hannah determines that

her patient is not getting enough air into his lungs. She instructs him to
take a large, deep breath. Then, she adds together the measurements
of TV, IRV, ERV, and RV. The figure is lower than it should be, alerting
Hannah to a problem. What capacity has Hannah MOST likely
calculated to measure her patient's breathing?
1
O inspiratory capacity
O functional residual capacity
vital capacity
O total lung capacity

Answer 1

The correct answer is - The total lung capacity

Step-by-step explanation:

The total lung capacity is the volume of air of an individual at the end of the maximum effort of inspiration. The total lung capacity can be found with the help of adding Tidal volume, The expiratory reserve volume, residual volume, and the inspiratory reserve volume at the end of deep large breathing.

In a healthy human being the total lung capacity is about 6,000 mL and the total air volume that can fill the lung.

(TLC = TV + IRV + ERV + RV).
