The survival time of patients who cannot be sealed after tracheotomy is subject to the treatment and recovery of the patient’s primary disease. Tracheotomy is a common clinical surgical procedure, especially when there is a serious neck injury and after major surgery, and the patient is in critical condition, tracheotomy can be used for mechanical ventilation, which is a measure to save the patient’s life in an emergency, so tracheotomy does not affect human life. The survival time of patients who cannot be sealed after tracheotomy depends mainly on the control of the primary disease and lung infection. If the patient’s primary disease is controlled and the lungs do not become infected repeatedly or with incurable infections, the tracheotomized patient can be kept alive for a long time, just like a normal person. If the primary disease is more severe, the patient’s life can be endangered at any time. In addition, after tracheal intubation, attention should be paid to the amount, color, nature and odor of tracheotomy secretions, as well as good oral care, timely cleaning of oral secretions, and keeping the tracheal tube in a neutral position so that the tube does not move to obstruct or fall off.
