Yintoni uvavanyo lweenqanaba leoksijini yegazi?

Uvavanyo lweqondo leoksijini yegazi, ekwabizwa ngokuba luhlalutyo lwegesi, ulinganisa inani leoksijini kunye nekhabhon diokside egazini. Xa uphefumla, imiphunga yakho ingenisa (inhale) ioksijini kwaye iphefumle (ikhuphe) icarbon dioxide. Ukuba kukho ukungalingani kumanqanaba oksijini kunye nekhabhon dioksi egazini lakho, oko kunokuthetha ukuba imiphunga yakho ayisebenzi kakuhle.

Uvavanyo lweqondo leoksijini yegazi lukhangela ibhalansi yeasidi kunye neziseko, ezaziwa njenge-pH balance, egazini. I-asidi eninzi okanye encinci egazini inokuthetha ukuba kukho ingxaki kwimiphunga yakho okanye kwizintso.

Amanye amagama: uvavanyo lwegesi yegazi, iigesi zegazi, i-ABG, uhlalutyo lwegesi, uvavanyo lwe-oxygen saturation

Isetyenziselwa ntoni?

Uvavanyo lweqondo leoksijini lwegazi lusetyenziselwa ukujonga ukuba imiphunga yakho isebenza kakuhle kangakanani kwaye ulinganise i-acid-base balance egazini lakho. Uvavanyo luhlala lubandakanya le milinganiselo ilandelayo:

• Umxholo weoksijini (O2CT). Oku kulinganisa isixa seoksijini egazini.
• Ukugcwaliswa kweoksijini (O2Sat). Oku kulinganisa isixa sehemoglobin egazini lakho. IHemoglobin yiprotein ekwiiseli ezibomvu zegazi ezithwala ioksijini kwimiphunga yakho iye kumzimba wakho uphela.
• Uxinzelelo okhethekileyo lweoksijini (PaO2). Oku kulinganisa uxinzelelo lweoksijini enyibilike egazini. Inceda ukubonisa ukuba ioksijini ihamba njani kwimiphunga yakho iye kwigazi lakho.
• Uxinzelelo oluyinxalenye lwekharbhon diokside (PaCO2). Oku kulinganisa isixa sekhabhon dayoksayidi egazini.
• pH. Oku kulinganisa ibhalansi yeasidi kunye neziseko ezisegazini.

Kutheni ndifuna uvavanyo lweoksijini yegazi?

Zininzi izizathu zokuba olu vavanyo luyalelwe. Unokufuna uvavanyo lweenqanaba leoksijini yegazi ukuba:

• Unengxaki yokuphefumla
• Unamaxesha okuba nesicaphucaphu kunye / okanye ukugabha
• Banyangwa isifo semiphunga, esifana nesifuba, isifo esinganyangekiyo semiphunga (COPD), okanye icystic fibrosis. Uvavanyo lunokunceda ukubona ukuba unyango luyasebenza na.
• Kutshanje wenzakele intloko okanye intamo yakho, enokuchaphazela ukuphefumla kwakho
• Ukuba libanda, iziyobisi
• Bafumana unyango lweoksijini ngelixa besesibhedlele. Uvavanyo lunokunceda uqiniseke ukuba ufumana inani elifanelekileyo leoksijini.
• Yiba ne-carbon monoxide yetyhefu
• Unobungozi bokubhema umsi

Umntwana osandul 'ukuzalwa unokufuna olu vavanyo ukuba unengxaki yokuphefumla.

Kwenzeka ntoni ngexesha lokuvavanywa kwenqanaba leoksijini yegazi?

Uninzi lweemvavanyo zegazi zithatha isampulu kwimithambo. Kolu vavanyo, umboneleli wezempilo uya kuthatha isampulu yegazi kwimithambo. Kungenxa yokuba igazi elivela kumthambo linamanqanaba aphezulu eoksijini kunegazi elivela emthanjeni. Isampulu ihlala ithathwa kwimithambo ngaphakathi kwesihlahla. Oku kubizwa ngokuba ngumthambo ojikelezayo. Ngamanye amaxesha isampuli ithathwa kwimithambo engqinibeni okanye kwi-groin. Ukuba usana olusandul 'ukuzalwa luvavanywa, isampuli ingathathwa kwisithende somntwana okanye kwintambo yomzimba.

Ngexesha lenkqubo, umboneleli wakho uya kufaka inaliti ngesirinji kwimithambo. Unokuziva iintlungu ezibukhali njengoko inaliti ingena emithanjeni. Ukufumana isampuli yegazi kumthambo kuhlala kubuhlungu kunokufumana igazi elivela emthanjeni, uhlobo oluqhelekileyo lwenkqubo yovavanyo lwegazi.

Nje ukuba isirinji igcwaliswe ligazi, umboneleli wakho uya kufaka i-bandage kwindawo yokugqobhoza. Emva kwenkqubo, wena okanye umboneleli kuyakufuneka ufake uxinzelelo oluqinileyo kwisiza kangangemizuzu emi-5 ukuya kweli-10, okanye nangaphezulu ukuba uthatha iyeza lokucoca igazi.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Ukuba isampulu yegazi yakho ithathiwe esihlahleni sakho, umboneleli wakho wezempilo angenza uvavanyo lokujikeleza olubizwa ngokuba luvavanyo luka-Allen ngaphambi kokuba uthathe isampulu. Kuvavanyo luka-Allen, umboneleli wakho uya kusebenzisa uxinzelelo kwimithambo esesandleni sakho imizuzwana eliqela.

Ukuba unyango lweoksijini, ioksijini yakho inokucinywa malunga nemizuzu engama-20 ngaphambi kovavanyo. Oku kubizwa ngokuba luvavanyo lomoya kwigumbi. Oku ngekhe kwenziwe ukuba awukwazi ukuphefumla ngaphandle kweoksijini.

Ngaba bukhona ubungozi kuvavanyo?

Kukho umngcipheko omncinci kakhulu wokuvavanywa kwenqanaba leoksijini yegazi. Kusenokwenzeka ukuba wopha, ukrunekile, okanye ukuba buhlungu kwindawo ebekufakwa kuyo inaliti. Nangona zinqabile iingxaki, kuya kufuneka uphephe ukuphakamisa izinto ezinzima iiyure ezingama-24 emva kovavanyo.

Zithetha ntoni iziphumo?

Ukuba iziphumo zakho zenqanaba leoksijini aziqhelekanga, oko kunokuthetha ukuba:

• Awuthathi ioksijini eyaneleyo
• Awususi ngokwaneleyo i-carbon dioxide
• Unokungalingani kwinqanaba lakho le-acid-base

Ezi meko zinokuba ziimpawu zesifo semiphunga okanye sezintso. Uvavanyo alunakukwazi ukuxilonga izifo ezithile, kodwa ukuba iziphumo zakho aziqhelekanga, umboneleli wakho wezononophelo lwempilo uya kuyalela iimvavanyo ezininzi ukuze aqinisekise okanye akhuphe isifo. Ukuba unemibuzo malunga neziphumo zakho, thetha nomboneleli wakho wezempilo.

Funda ngakumbi malunga novavanyo lwelabhoratri, uluhlu lweereferensi, kunye neziphumo zokuqonda.

Ngaba ikhona enye into endifuna ukuyazi malunga nokuvavanywa kwenqanaba leoksijini yegazi?

Olunye uhlobo lovavanyo, olubizwa ngokuba yi-pulse oximetry, lukwajonga amanqanaba eoksijini egazini. Olu vavanyo alusebenzisi inaliti okanye lufuna isampuli yegazi. Kwi-pulse oximetry, isixhobo esincinci esifana neklip esine-sensor ekhethekileyo iqhotyoshelwe kwiminwe yakho, uzwane, okanye i-earlobe. Kuba isixhobo silinganisa ioksijini "ngokungqamene" (kwindawo engaphandle), iziphumo zinikwa njenge-peripheral oxygen saturation, ekwabizwa ngokuba yi-SpO2.
