缺氧的

The responses of respiration to hypoxia is diphase,that is respiratory excitatory at first,then respiratory depression.

呼吸对缺氧的反应都是双相的,即先兴奋后抑制。

Syncope must be differentiated from epileptic seizures, although seizures due to brain hypoxia can occur in a syncopal episode.

晕厥必须与癫痫相鉴别，尽管在晕厥生脑缺氧引起的癫痫。
