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)?Predict Question 3: 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)? 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?When obstructive lung disease develops, what happens to the FEV1 (%)?Compared with the normal patient, what happened to the FVC in this patient?
