Spirometry: step by step

Educational aims To give an overview of what spirometry is, how to perform it and how to interpret it. To discuss the quality criteria to produce acceptable and reproducible results. To discuss the use of spirometry in the workplace. Summary Spirometry is easy to perform once trained and can be performed anywhere. It is useful for detecting early change and disease progression. Quality is important to ensure useful and reproducible results, otherwise results may be incorrectly interpreted. Training from a reputable centre should be undertaken to ensure the measures are understood as well as how to get the best results out of the patient.
