Craniocerebral injury patients, independent breathing when to recover, mainly depends on the severity of craniocerebral injury and injury site. 1. Craniocerebral injury site: for example, brainstem injury, especially medulla oblongata injury, because the medulla oblongata is the respiratory center of the human body, medulla oblongata injury respiration is affected, the patient often has no spontaneous respiration, the need to use a ventilator for assisted respiration, through the approximate 1 month or so of treatment, the patient began to gradually have a weak spontaneous respiration. 2. The degree of craniocerebral injury: craniocerebral injury is serious, bilateral pupil dilation, brain hernia formation, vital signs are unstable, respiration is affected, or even no spontaneous respiration, in order to fight for the opportunity to save the patient’s life, the need for emergency craniotomy to remove intracerebral hematoma and decompression therapy to remove the bone flap, due to the seriousness of the craniocerebral injury, the patient’s spontaneous respiration does not necessarily recover, which can lead to sudden death. Therefore, patients with craniocerebral injury need to go to the hospital in time and cooperate with the doctor actively, in order to fight for the first line to save the patient’s life.
