Which condition is typically monitored using Peak Expiratory Flow measurements?

Peak Expiratory Flow (PEF) measurements are primarily used to monitor asthma because they provide a straightforward and effective means of assessing how well air is being expelled from the lungs during expiration. Individuals with asthma may experience fluctuating airflow limitations, and PEF can help gauge the severity of their condition, identify triggers, and evaluate the effectiveness of medications or treatment plans.

In patients with asthma, measuring peak flow can indicate when their condition is worsening or when an asthma attack may be imminent, allowing for timely interventions. This monitoring helps patients and healthcare providers to make informed decisions regarding the management of the disease.

While Peak Expiratory Flow can be useful in other conditions like COPD, it is less frequently used compared to asthma for monitoring day-to-day changes in lung function.
