Endotracheal intubation and tracheotomy are one of the commonly used first aid methods for rescuing critically ill patients. They can improve dyspnea caused by various reasons, correct the patient's hypoxic state, improve ventilation function and effectively remove airway secretions. After the operation, the patient's trachea is connected to the outside world through a tracheal tube inserted into the trachea for gas exchange.
