Abstract

Optokinetic nystagmus (OKN) is used to study the eye's ReAdaptation Time (RAT) after a brief exposure to a light flash. The effects on RAT of breathing different concentrations of O2 are examined. Significant changes in RAT have been registered, showing that inhalation of 100% O2 as compared with room air, results in a shortened RAT (i.e. improvement), while inhalation of 9% O2 leads to an increased RAT (i.e. impairment). The physiology of RAT and the possible mechanisms behind the changes caused by different O2 concentrations are discussed. The findings of this group are compared with those of other studies.

摘要

视动性眼震（OKN）用于研究眼睛在短暂暴露于闪光后重新适应的时间（RAT）。研究了呼吸不同浓度的氧气对RAT的影响。已记录到RAT有显著变化，表明与室内空气相比，吸入100%氧气会导致RAT缩短（即改善），而吸入9%氧气会导致RAT增加（即损害）。文中讨论了RAT的生理学以及不同氧气浓度引起变化背后的可能机制。将该组的研究结果与其他研究的结果进行了比较。
