02/19/17 page 2Experiment ResultsPredict 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)?When an acute asthma attack occurs, many people seek relief from the increased airway resistance byusing an inhaler. This device atomizes the medication and induces bronchiole dilation (though it can also contain ananti-inflammatory agent). What lung values will change back to those of the normal patient in the spirogram after the asthma patient uses an inhaler(select all that apply)? Predict Question 4: During moderate aerobic exercise, the human body will change its respiratory cycle in order to meetincreased metabolic demands. During heavy exercise, further changes in respiration are required to meet the extrememetabolic demands of the body.Which lung value will change more during moderate exercise, the ERV or the IRV?Your answer : b. ERV Stop & Think Questions:When obstructive lung disease develops, what happens to the FEV1 (%)?
