This document defines and describes tracheostomy, including its purpose, indications, types of tubes, and care considerations. A tracheostomy is a surgical opening made in the trachea to help maintain airway patency or facilitate ventilation. Common indications include upper airway obstruction, need for pulmonary toilet or long-term ventilation. Tracheostomy tubes can be temporary or permanent. Proper care involves suctioning secretions, humidifying air, changing dressings aseptically, and assessing for potential complications like infection or inability to communicate.
