Total lung capacity (TLC) = Vital Capacity (VC) + Residual Volume (RV) Vital capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV) Total pulmonary ventilation (TPV) = Respiratory Rate (RR)* Tidal Volume (TV) Part 1: 1. If your VC is 4100 mL, your TV is 400 ml, and your ERV is 800 mL, calculate your Inspiratory Reserve Volume (show your work & include units): 2. Residual Volume typically represents approx. 20 % and vital capacity 80% of your lungs' Total Lung Capacity. Calculate how many liters of air represent your Residual Volume. Show your work & units. (Hint, start with the above measurements and this equation VC- (0.8) TLC to solve for TLC; then use additional equations above to solve for residual volume): TLC6L 3. Time your normal Respiratory Rate for 1 minute (# of inhales per minute), then use the above measurements to calculate your Total Pulmonary Ventilation (show your work & units): 11
