A cuffless tracheostomy tube is a medical device used to assist patients with breathing difficulties. Unlike a cuffed tracheostomy tube, it does not feature an inflatable cuff and relies on the natural seal created by the patient's airway. This type of tube may be used in patients who require less invasive ventilation or have a risk of tracheal injury. The use of a cuffless tracheostomy tube requires careful monitoring to ensure proper positioning and respiratory support.
