高压氧治疗能改善老年脑功能减退已有报道①。高压氧治疗老年人脑功能减退的主要机理之一是在于改善红细胞、血小板的生理功能、恢复红细胞变形能力和屈曲性以及减低红细胞和血小板的聚集性,从而改善微血流及微循环,进而改善脑、心、肺功能。由于肺功能改善、P_aO_2提高,进一步可较长时 Hyperbaric oxygen therapy can improve senile brain dysfunction has been reported ①. Hyperbaric oxygen treatment of the elderly one of the main mechanism of brain dysfunction is to improve the physiological function of red blood cells, platelets, red blood cells to restore resilience and flexibility and reduce the aggregation of red blood cells and platelets, thereby improving micro blood flow and microcirculation, thereby improving Brain, heart, lung function. As pulmonary function improved, P_aO_2 increased further longer
