Cishe abantu abayizigidi ezingu-80 bahlala ezindaweni ezingaphezu kwamamitha angu-2,500 ngaphezu kogu lolwandle.Njengoba ukuphakama kukhula, umfutho womoya uyancipha, okuholela ekucindezelekeni okuphansi kwe-oxygen ingxenye, engabangela kalula izifo ezinzima, ikakhulukazi izifo zenhliziyo.Ukuhlala endaweni enengcindezi ephansi isikhathi eside, umzimba womuntu uzobhekana nezinguquko eziguquguqukayo, njenge-right ventricular hypertrophy, ukugcina ukujikeleza kanye ne-tishu homeostasis.
“Umfutho ophansi” kanye “ne-hypoxia” kuhlobene eduze emzimbeni womuntu.Owokuqala uholela ekugcineni, obangela ukulimala okuphelele emzimbeni womuntu, okuhlanganisa ukugula kokuphakama, ukukhathala, i-hyperventilation, njll. Nokho, abantu baye bajwayela kancane kancane ukuze baphile ezindaweni eziphakeme, ukuphakama okungapheli okuhlala njalo kufinyelela kumamitha angu-5,370.
Ukugcwala komoyampilo wegazi kuyinkomba ebalulekile ye-hypoxia yomzimba womuntu.Inani elijwayelekile lingu-95% -100%.Uma ingaphansi kuka-90%, kusho ukutholakala kwe-oxygen eyanele.Uma ingaphansi kuka-80%, izodala umonakalo omkhulu emzimbeni.Ezindaweni eziphakeme ezingaphezu kwamamitha angu-3,000, ukuncipha kokugcwala komoyampilo egazini kungase kuholele ochungechungeni lwezimpawu, njengokukhathala, isiyezi, namaphutha ekwahluleleni.
Ngokugula kwe-altitude, abantu bangathatha izinyathelo ezihlukahlukene, njengokwandisa izinga lokuphefumula, ukushaya kwenhliziyo nokuphuma kwenhliziyo, futhi kancane kancane bakhulise ukukhiqizwa kwamangqamuzana egazi abomvu kanye ne-hemoglobin.Kodwa-ke, lezi zinguquko azivumeli abantu ukuthi basebenze ngokujwayelekile ezindaweni eziphakeme.
Endaweni emathafeni, kudingekile kakhulu ukusebenzisa izinto zokuqapha umoya wegazi ezifana ne-narigmed finger clip oximeter.Ingakwazi ukuqapha ukugcwala komoyampilo wegazi ngesikhathi sangempela.Uma umoya-mpilo wegazi ungaphansi kuka-90%, izinyathelo kufanele zithathwe ngokushesha.Lo mkhiqizo mncane futhi uyaphatheka, unokunemba kokuqapha kwebanga lezokwelapha.Kuyisisetshenziswa esibalulekile sokuhamba kwethafa noma umsebenzi wesikhathi eside.
