bronchodilator response

Bronchodilator response refers to how the airways in your lungs improve after using medication that relaxes the muscles around them. This test measures the change in airflow to see if the airways constrict or narrow due to conditions like asthma or COPD. If airflow increases significantly after using a bronchodilator, it indicates reversible airway narrowing, common in asthma. This helps doctors diagnose and tailor treatment strategies. Essentially, it assesses how well your lungs respond to medication that opens up your airways, providing valuable information about your respiratory health.
