Measuring Lung Volumes Tidal Volume (TV) You ask your lab partner to sit with their back straight. Then, instruct them to inhale a normal inspiration and exhale this air through the spirometer mouthpiece. To get the most accurate tidal volume, 3 measurements were recorded. a Measurement 1: 475 b. Measurement 2: 480 c. Measurement 3: 505 Expiratory reserve volume (ERV) You ask your lab partner to inspire a normal tidal inspiration, and breathe out a normal tidal expiration, then exhale as forcibly as possible into the spirometer mouthpiece. As before, several measurements were taken. a. Measurement 1: 800 b. Measurement 2: 850 c Measurement 3:780 Vital capacity (VC) Next instruct your subject to breathe several normal breaths, then bend over and exhale maximally. After they have exhaled as much air as possible, ask them to stand upright and inhale as much air as possible. Then, quickly place the mouthpiece to their mouth and exhale as forcibly and as long as possible. Three measurements were taken. a. Measurement 1:4,500 b. Measurement 2: 4.570 c. Measurement 3: 4,480 2 3 Calculate the average tidal volume. Round to the nearest whole number. Your lab partners average tidal volume is 487 10 points 8 Calculate the average expiratory reserve volume (ERV). Round to the nearest whole number. Your lab partners average expiratory reserve volume (ERV) is 803 ml. 10 points Calculate the average vital capacity (VC). Round to the nearest whole number. Your lab partners average vital capacity (VC) is 4517 ml. 10 points Even though the spirometer cannot measure inspiratory volumes, you can calculate this volume now that you have the vital capacity (VC), tidal volume (TV), and expiratory reserve volume (ERV), Recall that VC-TV+IRV +ERV. Rearrange the equation to solve for IRV IRV=VC- (TV+ERV) Measuring Lung Volumes Tidal Volume (TV) You ask your lab partner to sit with their back straight.
