Experiment Results
Predict Questions
1 Predict Question 1: With emphysema, there is a significant loss of elastic recoil in the lung
tissue and a noticeable, exhausting muscular effort is required for each expiration.
Inspiration actually becomes easier because the lung is now overly compliant.
Using the spirogram, calculate the lung value most affected by the emphysema condition.
Your answer: FEV1 .
2 Predict Question 2: During an acute asthma attack, airway resistance is significantly
