In fact, even though the experiment was super easy, it demonstrates exactly how our lungs work inside our bodies. In cases of obstructive lung diseases, such as asthma, bronchiectasis, COPD, and emphysema, the lungs are unable to expel air properly during exhalation. Take a deep breath in. In healthy adult participants, VC, SVC, and FVC are practically the same. In our experiment, however, we'll be using two methods of measuring lung capacity that we can make at home: the balloon method and the water d… Compare your vital capacity in each position. Measurement of lung volumes provides a tool for understanding normal function of the lungs as well as disease states. What is the average Get vaccinations like the flu vaccine and the pneumonia vaccine. You will need a balloon (the kind that blows up into a regular balloon shape, not the oblong sort), a measuring tape or ruler, and something to record data with and on. How does a spirometer measure tidal volume. Normal exhalation is passive, resulting from “recoil” of the chest wall, diaphragm, and lung tissue.
