What is one primary purpose of using a Peak Flow Meter in asthma management?

A Peak Flow Meter is primarily used in asthma management to assess lung function. This device measures the peak expiratory flow rate (PEFR), which indicates how fast air can be expelled from the lungs, providing valuable information about the state of a person's airway function.

By regularly using a Peak Flow Meter, individuals with asthma can track changes in their lung function over time. This monitoring helps in recognizing early signs of an asthma exacerbation, allowing for timely intervention and management adjustments. Understanding a patient's peak flow rate helps them and their healthcare provider identify when asthma control is slipping and when medication dosages may need to be altered.

Heart rate, blood pressure, and glucose levels are unrelated to the function of a Peak Flow Meter, emphasizing its specialized role in respiratory health rather than general physiological measurements.
