Hypoxia: stealth threat i hriat theih loh .

  ▶ 85-90% SPO2 : Lu na lo (dehydration nen a inthlau fo)
  ▶ 75-85% SPO2 : Zu rui driver-te thutlukna siam thiamna
  ▶ 70% hnuai lam SPO₂ : Hriat loh emaw thihna emaw hlauhawmna sang tak

I SPO2 chu hnuai lam a dip a 80% , mahse i dismiss a, is ' just fatigue .'

2. Rapid Killer Syndromes .

AMS (acute tlang natna): SPO2 <88% + lu na = vaukhânna hmasa ber a ni.

Hape (pulmonary edema): Spo2 crash + pink frothy spit = lungphu tuiin a khat

HACE (cerebral edema): SPO2 <70% + Confusion = Thihna atanga Darkar
