I. Purpose The purpose of this laboratory was to explore further pulmonary ventilation. During this laboratory experience factors that affect ventilation, such as diseased and exercise states, were simulated and measurements of ventilation were taken using a computerized spirometer. Also, this lab provided an opportunity to learn about the use of manual spirometers and how to interpret readings from these spirometers. II. Results 1. FVC (L) FEV1 (%) FEV3 (%) MVV (L/min) RV (L) 4.88 77.9 100 161.5 1.44 2. TLC = 5.52 L 3. (a) Control Data Averages: FVC (L) FEV1 (%) FEV3 (%) MV (L/min) RR (breaths/min) TV (L) MVV (L/min) RV (mL) 4.06 82.6 98.4 13.6 17 0.82 102.8 1405 (b) Restrictive Values: Control Value Restrictive Value FVC (L) 4.06 3.48 FEV1 (%) 82.6 85.6 The FVC values are what are expected during this condition, but the FEV1(%) values are not. Both values are expected to be lower during restrictive conditions because in conditions such as pulmonary fibrosis the elasticity of the lungs is decreased, thus the lungs are unable to expand to full capacity. Less airflow enters and leaves the lungs as a result of the decreased volume because the pressure gradient created by the difference in intrapulmonary and
