Which of the following is a method to monitor asthma symptoms?

Using a peak flow meter is an effective method for monitoring asthma symptoms because it measures the maximum speed of expiration, which reflects how well air moves out of the lungs. This is particularly valuable for individuals with asthma, as it allows them to gauge their respiratory function and identify changes that may indicate worsening asthma control or an impending attack. Regular use of a peak flow meter can help patients recognize patterns in their symptoms, enabling them to take proactive measures, such as adjusting medication or avoiding triggers, in a timely manner.

Daily temperature checks, electrical pulse measurement, and regular blood pressure monitoring do not specifically relate to asthma symptom management. They do not provide relevant information about lung function or airflow, which are critical for assessing asthma. Monitoring is best tailored to the specific conditions affecting a person, and a peak flow meter precisely addresses the needs of those with asthma.
