Spirometry and Pre- and Post-Bronchodilator Testing

Also known as: spirometry and pre and post.

What is spirometry and pre- and post-bronchodilator testing?

Spirometry is a common breathing test that measures the maximum force of a patient’s breath after inhalation and exhalation. Patients with asthma or other breathing problems may perform spirometry pre- and post-bronchodilator in order to examine the effectiveness of the medication on their breathing problems.

What happens during the procedure?

With a breathing apparatus in place, the patient will take a maximum inhalation, release maximum exhalation and then continue to exhale afterward. Then the patient will be treated with a bronchodilator. Finally, the spirometry test is repeated to determine how much the bronchodilator medication helped with breathing.
