近年来,人们利用正常组织与肿瘤组织间的生理学差异,开展了低氧放射治疗(HRT)。该方法既能保护正常组织,减轻放射反应,还可增强机体免疫力和提高疗效。但目前国内外均采用呼吸含氧10％左右的混合气造成缺氧,需要特殊设备、操作又麻烦。如用改进型低氧呼吸装置,可克服上述方法之不足,且造价低廉,尤其便于临床应用。本研究旨在观察癌症病人佩戴该装置的血气值改变,探索用以代替呼吸低氧混合气方法进行
In recent years, people use the difference between the normal tissue and tumor tissue to carry out hypoxia radiation therapy (HRT). The method not only can protect the normal tissue, reduce the radiation reaction, but also can enhance the body immunity and improve the curative effect. However, at present, both the domestic and foreign countries adopt the mixture of about 10% of the oxygen in the breath to cause hypoxia, which requires special equipment and the operation is troublesome. Such as the use of improved hypoxic breathing apparatus, can overcome the above deficiencies, and low cost, especially for clinical applications. The purpose of this study was to observe the changes in blood gas values of cancer patients wearing the device and explore ways to replace the breathing hypoxic mixture
