Spirometry  is one of the most common of the pulmonary function tests (PFTs), measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool used, in combination with the clinical picture, for diagnosing and assessing conditions such as asthma, COPD, pulmonary fibrosis and cystic fibrosis.

National Register for Spirometry

The links below are designed to describe the recently introduced process for joining the National Register for Spirometry. It covers the assessment and certification process, and recertification. It also lets you know about training options. There is also a Q&A available covering the questions we are asked most frequently.
