REVIEW SHEET EXERCISE 7 Respiratory System Mechanics NAME: Courtney Boyd LAB TIME/DATE: July 21, 2010 Pulmonary Function Tests The following questions refer to Activity 1: Measuring Respiratory Volumes. 1. What activity are you simulating when you click the ERV button? exhalation What additional muscles are used in this activity? Abdominal wall muscles and internal intercostals muscles 2. What was the MRV calculated in Activity 1? 3. What does the pump rate simulate? The pump rate simulates the beats per minute (BPM) The following questions refer to Activity 2: Examining the Effect of Changing Airway Resistance on Respiratory Volumes. 4. How did changing the radius effect FEV 1 (%)? As the radius decreased, the FEV 1 (%) decreases 5. What was the FEV 1 at a radius of 5.00 mm? 73.9% 6. Do the results suggest that there is an obstructive or restrictive problem? Explain. The results suggest that it is an obstructive problem because the FEV 1 at a radius of 5mm is low and the normal FEV 1 is between 75% and 85%. Simulating Factors Affecting Respirations The following questions refer to Activity 3: Examining the Effect of Surfactant. 7. What effect does the addition of surfactant have on the airflow?
