Peak Flow Monitoring

Peak flow monitoring is a simple yet effective way of performing airflow monitoring at home. There are a variety of hand-held devices on the market that can be used to monitor airflow.


Peak flow monitoring is done differently than spirometry. Peak flow is determined by a quick and hard breath into the device. Many reductions in airflow can be identified with this tool. The patient is assisted in setting up peak flow zones that correspond to certain interventions with medications in an Asthma Action Plan.

Additional Details

Although peak flow monitoring may not be used in every asthmatic, it can be very useful in some cases. The peak flow monitor is helpful not only during acute episodes, but is also helpful in following the course of asthma.
