高分压氧和高压氧对机体的作用和影响问题在实际潜水作业中和临床高压氧治疗中都经常涉及,因而对此问题的研究具有重要实际意义。颅腔是一个容积相对固定的腔隙,颅内脑组织、脑脊液和血液三者的相对恒定,维持正常颅内压力。颅内血液是唯一能很快起变化的成份,脑血流的变化直接影响颅内压力,同样,颅内压力的变化也可影响脑血流。已有实验证明,脑血流变化与颅内压力变化呈正相关。
The effects of hyperbaric oxygen and hyperbaric oxygen on the body are often involved in the actual diving operation and clinical hyperbaric oxygen therapy, so the research on this issue is of great practical significance. The cranial cavity is a relatively fixed volume of the lacunar, intracranial brain tissue, cerebrospinal fluid and blood relative to the three relatively constant, to maintain normal intracranial pressure. Intracranial blood is the only component that can change rapidly, and changes in cerebral blood flow directly affect intracranial pressure. Similarly, changes in intracranial pressure can also affect cerebral blood flow. Experiments have shown that cerebral blood flow changes and intracranial pressure changes was positively correlated.
