The Silent Summit Killer: Mun na aventurer bɛɛ mago bɛ pulse oximeter la .

Samiya bɛ ka surunya, kulu kanubaga minnu bɛ bɔ Alpɛ kuluw la ka taa Sinuwa kulu Siguniang, olu bɛ ka buguri bɔ u ka minɛnw na. Nka o vistas minnu ka kan ka kɛ Instagram-worthy ye, olu bɛ sonyali bagabagali dɔ dogo: Altitude hypoxia —farati min bɛ i farikolo la, o tɛna i lasɔmi fo n’a kɛra ko gɛlɛn ye.

Hypoxia: Stealth bagabagali i tɛ se ka min ye .
Ni 3000m ye, oksizɛni hakɛ bɛ jigin ni 30% ye, o bɛɛ n’a ta, i ka hakili degun taamasiɲɛw bɛ se ka kɛ abada. Case in point: 2024 Himalayan jiginnikɛla dɔ ye a ka oximeter ka 68% spo₂ lasɔmini jate, ka fɛnɲɛnamafagalan kɛ ka sɛgɛn walasa ka sɛgɛn.

•  Faratiyɔrɔw yebaliw
  ▶ 85-90% Spo₂ : Kungolodimi nɔgɔman (a bɛ kɛ ka caya ni farikolojidɛsɛ ye)
  ▶ 75-85% SPO₂ : Dɔlɔminna dɔlɔminna ka latigɛ seko
  ▶ 70% SPO₂ : faratiba bɛ sɔrɔ a la walima a ka saya .

• 'happy hypoxia' paradox
  i ka spo₂ tun bɛ se ka jigin ka se 75% ma k'a sɔrɔ i bɛ i yɛrɛ sɔrɔ dafalen na —i n'a fɔ 2023 Colorado Hiker min mago tun bɛ kisi la a kɛlen kɔ k'a sinsin a kan ko a 'Folt great' at 72%.

Farati fila minnu bɛ mɔgɔ faga, olu bɛ se ka kɛ sababu ye ka spo₂ 2 .

1. Hidroksia jaan nisɔndiyalen .

Aw ka spo3 bɛ jigin duguma 80% , nka aw bɛ a jate ' sɛgɛn dɔrɔn .'

Tiɲɛ : I hakili bɛ oksizɛni sɔrɔ kojugu fo a tɛ se ka farati dɔn.

Aw ka ɲɛnamaya hakilinaw bɛ farati taamasiɲɛw dogo.

2. Syndrome de fagalan teliyalenw .

AMS (Acute Mountain Backness): Spo3 <88% + Kungolodimi = Lakɔlɔsili joona .

Hape (Pulmonaire Edema): Spo2 Crash + Pink Frothy Spit = Fogonfogonw bɛ fa ni ji ye .

HACE (Cerebral Edema): Spo3 <70% + ɲagami = lɛrɛw ka bɔ saya la .
