The Silent Summit Killer: Adventurer zawng zawngin Pulse Oximeter an mamawh chhan

Mahse, chu Instagram-worthy vistas hnuaiah chuan hlauhawm ruk tak a thup a: altitude hypoxia —a hlauhawmna chu i taksain a critical hma loh chuan a hriattir lo ang che.

Hypoxia: Stealth Threat I hriat theih loh
3,000m-ah chuan oxygen level 30% zetin a tlahniam a, chutih rualin i thluak distress signals chu a thleng ngai lo mai thei. Case in point: Kum 2024-a Himalayan climber pakhat chuan a oximeter-a 68% SpO2 warning chu a ngaihsak lo va, cerebral edema chu hahna a ni tih a hre sual a ni.

  ▶ 85-90% SpO2 : Lu na na lo (dehydration nen a inzawm fo thin)
  ▶ 75-85% SpO2 : Zu rui driver-in thutlukna siam thiamna
  ▶ 70% hnuai lam SpO2 : Hriat lohna emaw thihna emaw hlauhawmna sang tak

Reality : I thluak hian oxygen a tlakchham lutuk a, hlauhawm a hre thei lo.

2. Rapid Killer Syndrome natna a awm thei

AMS (Acute Mountain Sickness): SpO2 <88% + lu na = hriattirna hmasa ber

HAPE (Pulmonary Edema): SpO2 crash + pink frothy spit = lung chhunga tuiin a khat

HACE (Cerebral Edema): SpO2 <70% + buaina = thih atanga darkar engemaw zat
