Experiment Results 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 now overly compliant. What lung values will change (from those of the normal patient) in the spirogram when the patient with emphysema is selected (select all that apply)? Your answer : a. TV e. FVC g. FEV1 h. FEV1 (%) Predict Question 2: During an acute asthma attack, airway resistance is significantly increased by (1) increased thick mucous 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 asthma attack is selected (select all that apply)? Your answer : a. TV e. FVC g. FEV1 h. FEV1 (%) Predict Question 3: When an acute asthma attack occurs, many people seek relief from the increased airway resistance by using an inhaler. This device atomizes the medication and induces bronchiole dilation (though it can also contain an anti-inflammatory agent). What lung values will change back to those of the normal patient in the spirogram after the asthma patient uses an inhaler
