Yintoni Ukuphakama Okuphantsi kwe-Po2 kwiGazi? Ukubaluleka kunye noLawulo lweNqanaba leOksijeni

Yintoni Ukuphazamiseka kwePo2?

Ukuphazamiseka kwePo2 kuthetha ukuba uxinzelelo lweoksijeni egazini lusezantsi kunomgangatho oqhelekileyo. Le meko ibonisa ukuba umzimba wakho awufumani ioksijeni eyaneleyo ayidingayo, kwaye ihlala ibonisa ingxaki enxulumene nenkqubo yokuphefumla. Ukwehla kwePo2 kubangela ukuncipha kweoksijeni efikelela kwiiseli nakwimithambo yomzimba. Ngenxa yoko, imisebenzi yemihla ngemihla inganzima, kungabakho ukulahleka kwamandla kunye neengxaki ezahlukeneyo zempilo.

Yintoni Ebangela Ukuphazamiseka kwePo2?

Ukuphazamiseka kwePo2 egazini kunokubangelwa zizizathu ezininzi ezahlukeneyo. Ezona zizathu zixhaphakileyo ziquka izifo zenkqubo yokuphefumla (umzekelo isifo sesifuba esingapheliyo - COPD, isifuba somoya, isifo sefiva yesifuba), iingxaki zentliziyo, izifo zegazi ezifana nesifo segazi esincinci kunye neengxaki zenkqubo yokujikeleza kwegazi. Ukongezelela koko, ityhefu ye-carbon monoxide okanye iimeko ezifana nokuphefumla okuphazamisekileyo ebusuku nazo zinokuchaphazela kakubi inqanaba lePo2.

Ubudala obuphambili, izifo ezingapheliyo, ukusilela kwemiphunga kunye neengxaki ezahlukeneyo zemetabolism nazo zinokunceda ekwehleni kwamaxabiso ePo2. Kuba izizathu zingahluka kumntu nomntu, kubalulekile ukuba ugqirha ahlole ukuze kufumaneke unobangela osisiseko.

Ukuphazamiseka kwePo2 Egazini Kuqatshelwa Njani?

Uqinisekiso oluchanekileyo lokwehla kwePo2 lufumaneka ngovavanyo lwegazi le-arterial. Kodwa olu vavanyo luhlala lucelwa xa kukho izikhalazo ezifana nokunqongophala komoya, intlungu esifubeni, isiyezi, okanye ukudideka kwengqondo. Kwakhona kwezi meko zilandelayo kuyacetyiswa ukuba kwenziwe uvavanyo lokuphazamiseka kwePo2:

• Isifo sesifuba esingapheliyo kunye nezinye izifo zesifuba

• Ukusilela kokuphefumla

• Ukuhlaselwa yintliziyo kunye nokusilela kwentliziyo

• Ukuphazamiseka okukhulu kokujikeleza kwegazi okanye ukuvaleka kwemithambo

• Ukulibaziseka kokubuyela kwimeko yesiqhelo emva kokufakelwa i-anesthesia

• Ityhefu ye-carbon monoxide okanye enye ityhefu

• Izifo zemiphunga kunye nezemetabolism

Nakuphi na ukuphazamiseka kokuphefumla, isiyezi esingalindelekanga okanye utshintsho kwengqondo, kufuneka uye kwindawo yezempilo kwaye uqinisekise ukuba kuvavanywa okufunekayo.

Zeziphi Iimpawu Zokuphazamiseka kwePo2?

Xa inqanaba lePo2 egazini lehla, ezi mpawu zilandelayo zinokubonakala:

• Ubunzima ekuthetheni, ukungakwazi ukufumana amagama

• Iingxaki zokugxila nokunaka

• Isiyezi okanye ukulahlekelwa yingqondo

• Intlungu kwindawo yesifuba

• Ubunzima okanye ukukhawuleza ekuphefumleni

• Ukudinwa okungapheliyo, ukwehla kwamandla

• Ukungabi namandla ngokubanzi kunye nokudinwa

Abantu abajongene nezi mpawu kufuneka bafune uncedo lwezempilo ngokukhawuleza kwaye, ukuba kuyimfuneko, benze uvavanyo lwegazi le-gas.

Ukuphazamiseka kwePo2 Kunyangwa Njani?

Unyango luxhomekeke kubangela bokuphazamiseka kwePo2 kunye nemeko jikelele yezempilo yomntu. Eyona ndlela ixhaphakileyo yokunyanga kukunika uncedo lweoksijeni. Ngokuxhaswa ngeoksijeni, inqanaba leoksijeni egazini linokunyuswa ngokukhawuleza, ngaloo ndlela kuqinisekiswe ukuba amalungu omzimba afumana ioksijeni ayidingayo.

Ukuba unyango lweoksijeni alwanelanga okanye ukuba isifo esingaphantsi sifuna unyango olwahlukileyo, unyango ngamayeza okanye ngamanye amaxesha iindlela zonyango ezibandakanya utyando zinokuthathelwa ingqalelo. Injongo ephambili kunyango kukufumanisa nokususa isifo esibangela ukuphazamiseka kwePo2. Kufuneka kulandelwe isicwangciso sonyango esilungele umntu phantsi kolawulo logqirha okhethekileyo.

Yintoni Emele Yenziwe Ukuze Inqanaba lePo2 Egazini Lihlale Lisesiqhelweni?

Uhlobo lobomi obusempilweni lunceda ekugcineni inqanaba lePo2 egazini. La manyathelo alandelayo axhasa impilo yesifuba nentliziyo kwaye anokuba luncedo:

• Ukuphepha ukusela ugwayi kunye notywala

• Ukubeka ingqalelo kumgangatho womoya, ukuphepha ukuhlala kwiindawo ezinemoya ongcolileyo ixesha elide

• Ukwenza umthambo rhoqo kunye nokuphila ubomi obusebenzayo

• Ukusela amanzi ngokwaneleyo, ukutya ngokulinganayo nangempilo

• Ukulawula ubunzima bomzimba, ukuzama ukuhlala kwinqanaba elifanelekileyo lobunzima

Ukuba kukho isifo esingapheliyo okanye ingxaki yokuphefumla, kubalulekile ukungaphoswa ziingxelo zonyango kunye nokulandela rhoqo.
