What is the primary function of a Peak Flow Meter?

The primary function of a Peak Flow Meter is to evaluate pulmonary function. This device is specifically designed to measure the maximum speed at which air can be blown out of the lungs. It helps in assessing the airway constriction in individuals with conditions like asthma or chronic obstructive pulmonary disease (COPD). By monitoring this measurement, healthcare providers can determine how well a patient's lungs are functioning and whether there are any changes that may require treatment adjustments.

The results from the Peak Flow Meter can be used to develop an action plan for managing a patient's respiratory health, enabling timely interventions when there is a decline in lung function.
