It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the test. In this experiment, the observers will use a “wet” spirometer to test the ability of the subject’s lungs by breathing in and out of the spirometer. During this test the subject will stand up and perform three breathing activities and record the measurements of each one. The hypothesis for this experiment is that the results are expected to be within normal range for each

These measurements had to be estimated because the machine that the subject was using was broken and it could not be calibrated right, so this required for the results to be a little off. This also caused for the calculations to not be accurate. The normal IRV ranges between 1900 and 3100mL, which means the IRV calculated is way below this range. The estimated vital capacity for the subject being tested is around 3080L based on the subject’s age and height. These type of test are very important because as stated before it helps monitor how well a person’s lungs are operating. It lets those testing know how much air is flowing in and out of the lungs in a normal respiration. If the results are not good then medical alternatives will be provided whether it is medication, breathing treatments, or surgery. The hypothesis was not proven true during this experiment because the results did not come out to be within normal range. If the spirometer was not broken then the results would have come out accurate and therefore the hypothesis would have been proven
