General information

The peak expiratory flow rate is the flow of air generated in the first 0.1 seconds of a forced expiration. It can be measured with a portable peak flow meter. The result is extrapolated over 1 minute and expressed in litres of expired air per minute.

- It is used to monitor asthma and to quantify the severity of a crisis, and can help to adjust treatment.

- A single value is of little relevance; multiple results for the same patients are required.

Specifications        

Hand-held device used to measure the air flow from the lungs in one "fast blast."

Suitable for adults and children.
