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
