Phantse abantu abazizigidi ezingama-80 bahlala kwiindawo ezingaphezulu kweemitha ezingama-2,500 ngaphezu komphakamo wolwandle.Njengoko ukuphakama kunyuka, uxinzelelo lomoya luyehla, nto leyo ekhokelela kuxinzelelo oluncinci lweoksijini, olunokuthi lubangele lula izifo ezibukhali, ngakumbi izifo zentliziyo.Ukuhlala kwindawo ephantsi koxinzelelo ixesha elide, umzimba womntu uya kutshintsha utshintsho, olufana ne-right ventricular hypertrophy, ukugcina ukujikeleza kunye ne-homeostasis yezicubu.
"Uxinzelelo oluphantsi" kunye "ne-hypoxia" zihlobene ngokusondeleyo emzimbeni womntu.Owokuqala ukhokelela ekugqibeleni, obangela umonakalo obanzi kumzimba womntu, kubandakanywa ukugula kokuphakama, ukukhathala, i-hyperventilation, njl.
Ukuzaliswa kweoksijini yegazi sisalathisi esibalulekileyo se-hypoxia yomzimba womntu.Ixabiso eliqhelekileyo li-95% -100%.Ukuba ingaphantsi kwama-90%, oko kuthetha ukungabikho kwe-oksijini eyaneleyo.Ukuba ingaphantsi kwama-80%, iya kubangela umonakalo omkhulu emzimbeni.Kwiindawo eziphakamileyo ngaphezu kweemitha ze-3,000, ukuncipha kwe-oxygen saturation yegazi kunokukhokelela kuthotho lweempawu, ezifana nokudinwa, isiyezi, kunye neempazamo ekugwebeni.
Kwisigulo esiphakamileyo, abantu banokuthatha amanyathelo ahlukeneyo, njengokunyusa izinga lokuphefumla, izinga lentliziyo kunye nokuphuma kwentliziyo, kwaye ngokuthe ngcembe bandise ukuveliswa kweeseli ezibomvu zegazi kunye ne-hemoglobin.Nangona kunjalo, olu hlengahlengiso aluvumeli abantu ukuba benze ngokuqhelekileyo kwiindawo eziphakamileyo.
Kwindawo ethe tyaba, kuyimfuneko kakhulu ukusebenzisa izixhobo zokujonga ioksijini yegazi njenge-narigmed finger clip oximeter.Inokubeka iliso kwi-oxygen saturation yegazi ngexesha langempela.Xa i-oxygen yegazi ingaphantsi kwe-90%, amanyathelo kufuneka athathwe ngokukhawuleza.Le mveliso incinci kwaye iyaphatheka, ngokuchaneka komgangatho wonyango.Sisixhobo esiyimfuneko sokuhamba kwithafa okanye umsebenzi wexesha elide.
