Peak flow meter demonstration

A peak flow meter is an aerosol generating procedure (AGP) and performing should be avoided in healthcare settings when there is a risk of cross-contamination e.g. during the COVID pandemic, if the patient may have an infection like TB. Using ones own peak flow at home is better.

In this video, a healthcare worker demonstrates how to use a peak flow meter.

False high readings can occur if the incorrect technique is used on a peak flow meter e.g. accelerating the airflow by spitting or putting your tongue inside the mouthpiece. (Connelly, 1987)
