This study addresses the question of whether repeated acute exposure to hyperbaric oxygen, such as encountered in O2 diving, affects the peripheral oxygen chemosensors. Groups of nondivers, active O2 divers, and ex-O2 divers, as well as active air scuba divers, were given 1 or both of 2 tests that measure the ventilatory response to transient hypoxia. Results showed that all groups of divers have a mean response similar to or higher than that of nondivers as well as that of normal subjects, as reported in the literature. A repeat test on 10 diving candidates before and after 200 h of accrued O2 diving also did not show an impairment in the hypoxic ventilatory response. Oxygen diving within the established depth and time limits does not seem to cause cumulative damage to the peripheral O2 chemosensors.
本研究探讨了反复急性暴露于高压氧(如在氧气潜水中所经历的)是否会影响外周氧化学感受器这一问题。将非潜水者、现役氧气潜水员、退役氧气潜水员以及现役水肺潜水员分组,进行了两项测量对短暂性低氧通气反应的测试中的一项或两项。结果显示,正如文献报道的那样,所有潜水员组的平均反应与非潜水者以及正常受试者的相似或更高。对10名潜水候选者在累计200小时氧气潜水前后进行的重复测试也未显示低氧通气反应受损。在既定的深度和时间限制内进行氧气潜水似乎不会对外周氧化学感受器造成累积性损害。
