spirometry

— Spirometry is typically the first PFT^([Pulmonary Function Test]) to be performed in a patient. This is because the indications for performing spirometry are extensive (Table 56-3). The indications are so numerous, in fact, that it is a surprise that spirometry is so greatly underused. There are several perceived and real barriers to its use, but these can be easily overcome by studying spirometry interpretation guides and by getting the right equipment and good training.
