For many decades, requiring patients to make forced, maximal exhalations to measure their expiratory volumes and flows, has been the standard of care for pulmonary function testing (PFT).

However, despite its wide acceptance and abundant clinical use, Spirometry suffers from several shortcomings and limitations for patient assessment and diagnosis. This document discusses the strengths and weaknesses of Spirometry and contrasts thbeyond-spirometry-thumbnailem with oscillometry, a novel and complementary technique to assess pulmonary function during quiet, tidal breathing that requires minimal patient effort and coordination.

The Basics:

Spirometry vs. Oscillometry

Spirometry requires patients to take a deep breath and then to exhale maximally for at least six seconds. A skilled health care professional is needed to properly coach […]
