Spirometry in Charlottesville

Spirometry involves the use of a spirometer for making pulmonary function measurements to evaluate airway obstruction and its reversibility with use of a bronchodilator. Simply stated, this involves measurement of the volume and/or speed of flow of air that can be inhaled and exhaled. Many spirometers display graphs, called spirograms, including volume-time curve and a flow-volume loop. Spirometry is often used to diagnose and better understand the severity of asthma. In individuals with such respiratory problems, spirometry may be recommended 1) at the initial visit, 2) to evaluate the response to a change in therapy and also 3) after initiation of treatment once the peak expiratory flow and symptoms have stabilized. Furthermore, it is recommended at least once a year in patients to reassess maintenance of airway function, regardless of any changes in medication.
