Hyperbaric oxygen is not available for patients with cerebral hemorrhage. Hyperbaric oxygen is generally indicated mainly for severe carbon monoxide poisoning, drug toxic encephalopathy or food poisoning encephalopathy. Patients with cerebral hemorrhage are mainly admitted to brain surgery for comprehensive treatment. If surgery is suitable, surgical treatment can be considered. When surgery is not suitable, conservative treatment should be performed, including cranial pressure-lowering therapy, neuroprotective therapy, and active control of the etiology and complications. The main causes of cerebral hemorrhage include hypertension and cerebral aneurysm, and common complications include aspiration pneumonia, urinary tract infection, and decubitus infection. If the patient is bedridden for a long time, it may cause deep vein thrombosis in the lower extremities, which can cause pulmonary tethering of the patient. In the case of brainstem hemorrhage, bulbar palsy can occur, manifesting as difficulty in swallowing and choking on water, easy aspiration leading to patient death and easy aspiration pneumonia. If it is difficult to recover in the short term, the gastric tube should be lowered as soon as possible, and nasal feeding diet and medication can be given.
