Learn how BT has helped people with severe asthma gain control of their asthma symptoms and improve their asthma-related quality of life.

The Alair Bronchial Thermoplasty System is indicated for the treatment of severe persistent asthma in patients 18 years and older whose asthma is not well controlled with inhaled corticosteroids and long-acting beta-agonists.

As with any procedure, there are risks, and individual results may vary. The most common adverse event of BT is a temporary worsening of respiratory-related symptoms. These events typically occur within one day of the BT procedure and usually resolve within a week with standard care. There is a small risk (3.4% per procedure) that symptoms may require hospitalization.2
