Cerebral hemorrhage without independent respiration mainly includes the following two major reasons: 1. The amount of cerebral hemorrhage is relatively large, causing the formation of cerebral hernia, and the compression of the brain stem, thus affecting the respiratory function of the patient. For this type of patients, the prognosis is very poor, the mortality rate is very high, even after active surgical treatment, its prognosis will not be too good. 2, due to the influence of drugs, for example, in order to make sure that the patient can ensure adequate oxygenation, the early stage of the patient may need to use the ventilator to assist ventilation. Due to some patients can not be very good tube resistance, routine need to use analgesic, sedative drugs to deal with, and interrupt the patient’s voluntary breathing, the patient’s respiratory function is mainly dependent on the ventilator to maintain, to ensure that the body does not lack of oxygen, and thus for the treatment of the disease is very helpful. For the use of analgesic, sedative drugs for the treatment of patients, subsequent stabilization of the condition, you can stop using analgesic, sedative drugs, subsequent with the discontinuation of analgesic, sedative drugs, independent breathing will also be slowly restored.
