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)? Your answer : a. TV b. ERV c. IRV d. RV e. FVC g. FEV1 h. FEV1 (%) 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? When obstructive lung disease develops, what happens to the FEV1 (%)? Compared with the normal patient, what happened to the FVC in this patient? Compared with the normal patient, what happened to the FEV1 in this patient? Compared with the normal patient, what happened to the FVC in this patient? Compared with the normal patient, what happened to the FEV1 in this patient?

02/21/15 page 3 Which values in this spirogram have notreturned to those of the normal patient (select all that apply)? For both types of exercise, the tidal volumes and breathing rates were increased. Compared with normal values, did tidalvolume or breathing rate increase more during moderate exercise? (Determine the percentage by which each valuechanged.)
