You have just given your patient a 0.03 mg/ml dose of methacholine to assess for asthma. The subsequent forced vital capacity (FVC) shows no change. What should you do next?

Which of the following statements are true regarding measurement of the patient’s forced vital capacity (FVC)?1. The patient can be sitting or standing.2. Nose clips are not required.3. It is an effort-dependent test.4. Accurate results can be obtained without patient cooperation.

The pulmonary function technologist is performing a post bronchodilator spirometry test on a 70-years-old man. The patient completed the SVC capacity maneuver without incident, however the patient fainted during the FVC maneuver. The most likely explanation is that

The results of flow-volume loop study indicate that the inspiratory flow curve is normal, however the expiratory flow curve is decreased. Based upon these results, the technologist should interpret these results as

Which of the following tests is considered the best application for routine monitoring of patients with asthma to measure gross changes in airway function before and after a bronchodilator?

The following volumes are reported for a patient. TLC = 5.4L, RV =1.0L, IRV= 2.6L, VC =4.2L, ERV =1.0L , VT= 0.6L, FRC =2.0L , IC= 3.2L Which of the following capacities is erroneous
