Endotracheal intubation plays a crucial role in intensive care, serving as a vital means to maintain airway patency and ensure effective ventilation and oxygenation for critically ill patients. In the Intensive Care Unit (ICU), endotracheal intubation is often employed for patients requiring mechanical ventilation support, particularly in cases of acute respiratory failure, severe trauma, pneumonia, and anesthetic emergencies.
