Predict Question:
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 nowoverly compliant.What lung values will change (from those of the normal patient) in the spirogram when the patient with emphysema isselected (select all that apply)?
During an acute asthma attack, airway resistance is significantly increased by (1) increased thickmucous secretions and (2) airway smooth muscle spasms. What lung values will change (from those of the normal patient) in the spirogram when the patient suffering an acute asthmaattack is selected (select all that apply)?
