This manifests as a decrease in forced vital … WebIC = TV + IRV. objectives. 1. measure tidal volume, inspiratory reserve volume, and expiratory reserve volume. 2. calculate inspiratory capacity, vital capacity, and the % observed vital capacity to the average values for comparison. 3. compare your observed vital capacity with the predicted vital capacity.
