An Endotracheal Tube (ET Tube), also known as an endotracheal tube, is a medical device used to establish and maintain a patent airway in patients who require assisted ventilation or are under anaesthesia. It is a flexible tube made of plastic or rubber that is inserted through the mouth or nose and passed down the trachea (windpipe) into the main airway of the lungs.
ET tubes come in various sizes to accommodate patients of different ages and sizes. The correct size is selected based on the patient’s age, weight, and clinical condition to ensure proper ventilation and minimise the risk of complications.
