Why must the lung be able to return to its normal non-deflated shape? and describe the factors which enable this to happen.
How would restrictive lung disease alter residual volume? Why?
Indicate whether the changes in respiratory volumes or capacities described are observed A) during an acute asthma attack, B) in emphysema C) both during an acute asthma attack and in emphysema, or D) not during an acute asthma attack or in emphysema.
Note that the acute asthma attack is in a person not taking ventolin (ie no inhaler).
Decrease in total lung capacity
Increase in residual volume
Decrease in FEV1 (forced expiratory volume in one second)
Decrease in tidal volume
Decrease in expiratory reserve volume
