Go to this site: and input information on test subjects. The resulting figures are: Vital capacity (VC) 4.8 L Inspiratory capacity (IC) 3.5 L Functional residual capacity (FRC) 2.5 L Total lung capacity (TLC) 6 L. Have each of your subjects record their data. Tidal volume 0.5 L Expiratory reserve volume 1.3 L Residual volume 1.2 L. This online calculator will use your height and age to estimate your vital capacity. Research has shown that the capacity of a person's lungs is proportional to the surface area of his body and his height. Convert the diameter to volume using the graph and record this on your table. Pinch the end of the balloon and measure its diameter in cm. Take a deep breath and then exhale into the balloon. Measuring Vital Capacity - Stretch a round balloon several times to stretch it out. Choose 3 subjects from your group and record data on their height, age, sex, and activity level.Ģ. You will be using the diameter of a balloon and the graph shown to estimate your capacities.ġ. If you have any breathing difficulties (asthma or other condition), you should not participate. Such air is located in the anatomical dead space within bronchi and bronchioles-that is, outside the alveoli.In this activity, you will be measuring the vital capacity of members of the class. Some of the air in the lungs does not participate in gas exchange. The functional residual capacity (FRC), about 2,400 mL, is the amount of air remaining in the lungs after a normal expiration (FRC = RV + ERV).The inspiratory capacity (IC), about 3,600 mL, is the maximum amount of air that can be inspired (IC = TV + IRV).The value varies according to age and body size. The vital capacity (VC), about 4,800 mL, is the total amount of air that can be expired after fully inhaling (VC = TV + IRV + ERV = approximately 80 percent TLC).The total lung capacity (TLC), about 6,000 mL, is the maximum amount of air that can fill the lungs (TLC = TV + IRV + ERV + RV).Summing specific lung volumes produces the following lung capacities: Residual volume (RV), about 1,200 mL, is the volume of air still remaining in the lungs after the expiratory reserve volume is exhaled.The expiratory reserve volume (ERV), about 1,200 mL, is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume. The inspiratory reserve volume (IRV), about 3,100 mL, is the additional air that can be forcibly inhaled after the inspiration of a normal tidal volume.The tidal volume (TV), about 500 mL, is the amount of air inspired during normal, relaxed breathing.The following terms describe the various lung (respiratory) volumes: Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle.

Tidal volume (TV) measures the amount of air that is inspired and expired during a normal breath. Lawrence PDF, 2.49 MB Volume 3 - 2023/03 St. The volume in the lung can be divided into four units: tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume.
