This rapid breathing causes hypocapnia, a drop in the blood's carbon dioxide levels.

这种快速呼吸会导致低碳酸血症，即血液中二氧化碳浓度下降。

Likewise, mild hypocapnia might be beneficial treatment as a temporary measure when treating cerebral edema, but hyperventilation could cause cerebral vasoconstriction.

同样，轻度低碳酸血症作为治疗脑水肿的临时措施可能是有益的治疗，但过度通气会导致脑血管收缩。

The drop in CO2 that occurs in your blood when you hyperventilate is called hypocapnia, and it signals a breakdown in one of the most complex and important functions that your respiratory system performs.

当你过度呼吸时血液中二氧化碳的下降被称为低二氧化碳，它标志着你呼吸系统执行的最复杂和最重要的功能之一的崩溃。

This device allows users to kill themselves relatively painlessly by inducing hypoxia and hypocapnia (the state of inadequate oxygen supply at the tissue level and reduced carbon dioxide in the blood leading to death).

该设备允许用户通过诱导缺氧和低碳酸血症（组织水平供氧不足和血液中二氧化碳减少导致死亡的状态）相对无痛地自杀。
