3 1 For a person suffering an asthma attack, inhaler medications are expected to You correctly answered: reduce the airway resistance. 4 Which of the following values does not include the ERV? You correctly answered: TV. 5 What would be an example of an everyday respiratory event the ERV simulates? 1
4/8/2020 PhysioEx Exercise 7 Activity 1 6/6 Your answer: Exhalation would be an everyday respiratory event that stimulates ERV. What additional skeletal muscles are utilized in an ERV activity? Your answer: Abdominal wall muscles and internal intercostal muscles. 2 What was the FEV (%) at the initial radius of 5.00 mm? Your answer: 74%. 3 1 What happened to the FEV (%) as the radius of the airways decreased? How well did the results compare with your prediction? Your answer: The FEV percentage decreased when the radius airway decreased, as I predicted. 4 1 Explain why the results from the experiment suggest that there is an obstructive, rather than a restrictive, pulmonary problem. Your answer: With FEV1 percentage decrease, signifies that there is a reduction in the amount of air that has passed through the airways. There must be an obstruction that is affecting the air that passes through the airways. 5
