近年来,有关氧毒问题已引起临床上的重视。但应防止因噎废食,对需要氧治疗的病人而没有正确处理。因此,有必要对氧毒性机理,及有关的因素进一步探讨。氧毒性的突出表现在肺,也可认为是毒性的靶器官。但还涉及多个系统和器官如中枢神经,视网膜,造血和内分泌等。不同种动物对氧毒性的敏感并不相同,就是同一个体在不同的时间里,对氧的耐受性也不尽同。这取决于多种可变因素如年龄,营养,内分泌状态,以及事先是否用过氧和其它氧化剂。 In recent years, the issue of oxygen toxicity has caused clinical attention. However, it is necessary to prevent the waste of food, which is not properly handled by patients who need oxygen therapy. Therefore, it is necessary to further study the mechanism of oxygen toxicity and related factors. Oxygen toxicity prominent in the lungs, can also be considered as toxic target organ. But also involves a number of systems and organs such as the central nervous system, the retina, hematopoietic and endocrine. Different species of animal oxygen sensitivity is not the same, that is, the same individual at different times, tolerance of oxygen are not the same. It depends on a variety of variables such as age, nutrition, endocrine status, and whether oxygen and other oxidants are used in advance.
