Coma and snoring in brain hemorrhage is mainly due to the relatively large amount of brain hemorrhage compressing the brainstem, thus affecting the patient’s respiratory function, because the human body’s breathing and circulation are regulated by the brainstem. Ventilator-assisted ventilation needs to be considered for such patients, because snoring in comatose patients can easily lead to hypoxia in the organism. If the body is hypoxic, it will further aggravate the hypoxia of brain cells in the skull, which will eventually lead to brain swelling resulting in cerebral edema again, thus causing an increase in intracranial pressure. When the intracranial pressure increases to a certain degree, it will affect the patient’s consciousness, and in serious cases, it may affect the patient’s life. Therefore, treatment requires interrupting the patient’s spontaneous breathing through moderate analgesia and sedation, and using ventilator-assisted ventilation to ensure that the patient is not hypoxic. During the use of the ventilator, it is necessary to ensure that the patient’s blood gas oxygenation index is greater than 300 PaO2/FiO2 in order to play a role in the patient’s recovery.
