Lung Volumes and Capacities · Physiology

If a patient has a Total Lung Capacity of 6.0 L and a Functional Residual Capacity of 2.5 L, what is their Inspiratory Capacity?

  1. 8.5 L
  2. 3.5 L
  3. 2.5 L
  4. 1.5 L
Show answer and explanation

Correct answer: 3.5 L

The Total Lung Capacity is the sum of Inspiratory Capacity and Functional Residual Capacity ($TLC = IC + FRC$). Therefore, $IC = 6.0 - 2.5 = 3.5$ L.
