Simple spirometry to measure airway flow rates can help in identifying reversible or fixed airway obstruction. A reduced forced vital capacity in the absence of airflow obstruction is supportive evidence of restrictive lung disease. Spirometry can be performed during the initial workup or a follow-up visit in an outpatient clinic. The patient can use a peak flow meter to monitor his or her airflow at home. Airflow rates can be helpful in determining necessary adjustments for medications, depending on the patient's clinical course.
