An endotracheal tube (ETT) is a critical medical device used to secure a patient’s airway during surgeries, emergencies, or intensive care. This flexible plastic tube facilitates mechanical ventilation, ensuring oxygen reaches the lungs when a patient cannot breathe independently. Understanding its design and functionality is essential for medical professionals.
Core Components and Functions
The endotracheal tube comprises several precision-engineered parts. Its diameter, defined by the internal measurement in millimeters, determines airflow capacity. A beveled tip aids visual placement during intubation, while Murphy’s eye—a secondary opening—prevents complete obstruction if the primary bevel is blocked. The cuff, an inflatable balloon, seals the trachea to minimize aspiration risks and deliver oxygen efficiently. Connected to the cuff, a pilot balloon and one-way valve allow controlled inflation. Finally, the 15mm adapter links the endotracheal tube to ventilators or Ambu bags for life-sustaining oxygen delivery.
Applications in Critical Care
ETTs are indispensable in operating rooms, ICUs, and trauma scenarios. They enable anesthesia administration during surgery and provide prolonged respiratory support for patients with respiratory failure. Proper placement, verified via auscultation or capnography, prevents complications like pneumothorax. The endotracheal tube also protects against gastric aspiration, making it vital in unconscious or critically ill individuals.
