A tracheostomy is a surgically made hole that goes through the front of your neck into your trachea, or windpipe. A breathing tube, called a trach tube, is placed through the hole and directly into your windpipe to help you breathe. A tracheostomy may be used to help people who need to be on ventilators for more than a couple of weeks or who have conditions that block the upper airways.
Sometimes pneumothorax occurs during diving or high-altitude flying, probably as a result of air pressure changes in the lungs. A pneumothorax may follow an injury or a medical procedure allows air to get into the pleural space.
