A tracheostomy provides another way for oxygen-rich air to reach your lungs, besides going through your nose or mouth. A breathing tube, also called a trach (trake) tube, is put through the tracheostomy and directly into the windpipe to help you breathe. Doctors use tracheostomies for many reasons.One common reason is to help people who need to be on ventilators (VEN-til-a-tors) for more than a couple of weeks.Ventilators are machines that support breathing. If you have a tracheostomy, the trach tube connects to the ventilator.People who have conditions that interfere with coughing or block the upper airways also may need tracheostomies. Coughing is a natural reflex that protects the lungs. It helps clear mucus (a slimy substance) and bacteria from the airways.octors use tracheostomies for many reasons.

Tracheal stenosis is narrowing of the trachea, or windpipe. Tracheal stenosis causes shortness of breath, which is made worse during exercise.Noisy breathing can be heard when tracheal stenosis is severe.1  Scar formed from the tip of a breathing tube.reatment for tracheal stenosis enlarges the size of the airway, thus making breathing easier. In the operating room bronchscopy is performed with the patient asleep. Sometimes a laser is used to cut the narrowed portion of the airway from the inside.
