• Females of pregnancy, or positive pregnancy test prior to randomization
• Participating in other drug or medical device clinical trials
• Patients with extensive bleeding or severe increase in infarct area, midline displacement (>0.5cm), etc. during endovascular treatment, who plan to undergo bone valve decompression or ventricular drainage
• Severe persistent and medication-uncontrollable hypertension (systolic blood > 185 mmHg or diastolic blood > 110 mmHg)
• End-stage disease other than the nervous system, life expectancy < 90 days
• Patients with anemia, polycythemia or other conditions requiring urgent oxygen
• Unable to cooperate with hyperbaric oxygen therapy, or have other diseases that are not suitable for hyperbaric oxygen therapy (such as active/chronic obstructive pulmonary disease, acute respiratory distress syndrome, tension pneumothorax, tension pneumocephalus, etc.)
• Known bleeding risk factors, including coagulation factor deficiency, or receiving anticoagulant therapy, INR>3.0 or APTT > 3 times normal or platelet count less than 50×10⁹/L
• Severe hepatic or renal dysfunction (severe hepatic dysfunction refers to ALT or AST > 3 times the upper limit of the normal range, severe renal dysfunction refers to serum creatinine Cr >1.5 times the upper limit of the normal range)
• Baseline blood glucose of <50 mg/dL (2.78 mmol/L) or >400 mg/dL (22.20 mmol/L)
• The oxygen required to maintain 95% of peripheral arterial oxygen saturation (SaO2) under the current medium-term management guidelines > 3L/min
• CT or MR suggests intracranial tumors (other than meningiomas) or other high-risk intracranial vascular malformations
