The researchers noted that cognitive issues identified during the prospective study appear to be associated with hypoxia rather than with the quality and duration of sleep .
研究人员指出,在前瞻性研究中被证明认知障碍的发生似乎是与缺氧有关,而与睡眠质量和时间无关。
Rapidly-growing tumours often outstrip their blood supply . This results in chronically low levels of oxygen in the tumour cells , a condition called hypoxia .
肿瘤快速生长的速度超过了血液的供应速度,这就导致低氧(即肿瘤细胞内的长期低氧气供应量)情形的发生。
Since you need to breathe more to compensate for low oxygen at high altitudes , drinking could make you more likely to experience hypoxia .
在低氧的高海拔地区,你必须多呼吸,而渴酒会让你缺氧的可能性提高。
At 18000ft ( 5490m ) , experts say , hypoxia will set in , causing weakness , tremors , light-headedness and visual impairment .
In humans this system responds to hypoxia , such as is caused by high altitudes or physical exertion , and is very important for the prevention of stroke and heart attacks as well as some types of cancer .
Since the study findings demonstrated a consistent correlation between hypoxia measures and the subsequent development of cognitive impairment , the researchers suggested that further investigation of continuous positive air pressure ( cpap ) treatment be undertaken .
He hopes xtreme everest will confirm dr montgomery 's work by showing that how well a person deals with hypoxia is related to the efficiency with which his cells utilise oxygen-and that this , in turn , is genetically determined .
