The Alair Bronchial Thermoplasty System's main method of treatment is through radio-frequency energy. The energy from the system heats lung tissue that decreases inflammation of the airways due to asthma. This new treatment has been FDA approved and is specifically meant for people with severe asthma. The system is manufactured by Asthmatx, and is being closely observed.
Also to keep in mind, "side effects during the course of treatment may include asthma attacks, wheezing, chest tightness or pain, partially collapsed lung (atelectasis), coughing up blood (hemoptysis), anxiety, headaches, and nausea."
