Abstract
Methods of increasing gas exchange performed by the lung by damaging lung cells, damaging tissue, causing trauma, and/or destroying airway smooth muscle tone with an apparatus inserted into an airway of the lung. The damaging of lung cells, damaging tissue, causing trauma, and destroying airway smooth muscle tone with the apparatus may be any one of or combinations of the following: heating the airway; cooling the airway; delivering a liquid to the airway; delivering a gas to the airway; puncturing the airway; tearing the airway; cutting the airway; applying ultrasound to the airway; and applying ionizing radiation to the airway.
