Determine the Patient's predicted vital capacity using the provided tables. Predicted VC = ml. Is the Patient's measured vital capacity greater than, equal to, or less than their estimated (predicted) vital capacity? It is common to compare a patient's measured vital capacity to their est imated (predicted) vital capacity as a percentage. Calculate the Patient's percent predicted VC. Show all work. % predicted VC = VCmeasured X 100 VCpredicted % predicted VC = Note: Vital capacities are dependent on other factors besides age and height. Therefore, 80% of predicted values are still considered "normal." Total Lung Capacity (TLC) is the maximum capacity of the lungs and is calculated as follows: TLC = VC + RV (where RV= 25% VC in females, 33% of VC in males) First, calculate the Patient's residual volume. Use the Patient's measured vital capacity in ml. Show all work. RV = VC x 0.25 (females) RV = VC x 0.33 (males) RV = RV = ml
