Ukuhlolwa kwegesi egazini yegazi, eyaziwa ngokuthi i-ABG, kwenziwa ngegazi elidonsa emthini . Isetshenziselwa ukubona ukuthi amaphaphu asebenza kanjani kahle futhi anqume ukusebenza kahle kwemithi yokuphefumula, njengokusebenzisa i- ventilator , i-CPAP, i-BiPAP noma i-oxygen. Igazi legazi lingabonisa nokuthi kunezinkinga zezinso, kodwa ngokuvamile azenzelwe ukuxilonga izinkinga ngezinso.
I-ABG ingenye yezinto ezivame ukuhlolwa ngaphambi kokuhlinzwa, ikakhulukazi ezigulini ezinezinkinga zokuphefumula noma izifo zamaphaphu. I-ABG kufanele ilindeleke uma ukuhlinzeka isikhathi eside, noma ngabe isiguli siyobe sesesithombeni isikhathi eside. Lokhu kwenza abasebenzi bazi ukuthi izilungiselelo zokuphuza umoya zifanele yini isiguli.
Ukudweba i-ABG
Kunezindlela ezimbili zokudweba i-ABG: umugqa wokuguqula (uhlobo olukhethekile lwe-IV line elifakwa emthini ovumela igazi lokuguga ukuba ludonse ngaphandle kwenaliti) noma isirinji ukudweba igazi emthini.
Ukudweba kwegazi okuphambene nakho kuyabuhlungu kakhulu kunokudweba kwegazi okwejwayelekile, futhi kuvame ukuqhutshwa esihlakaleni noma ukubola. Ngemuva kokukhishwa kwegazi, ingcindezi ingase isetshenziswe kwisayithi imizuzu emihlanu noma ngaphezulu ukuvimbela ukuphuma kwegazi emthonjeni. Uma isiguli kulindeleke ukuthi sibe se-ventilator isikhathi esingeziwe, umugqa wokuguqula uvame ukufakwa ukuze ugweme izinti eziphindaphindiwe ezibuhlungu.
Umugqa wokuguqula uvumela igazi ukuba lithathwe emthini ngaphandle kokunamathela isiguli ngenaliti ngaso sonke isikhathi. Ukwengeza, umugqa wokuguqula uvumela ukuqapha okunamandla okunembile kwegazi okuqhubekayo.
Ukuhlolwa
I-ABG ibheka izingxenye eziyisihlanu zegazi lokugaya:
- i-pH : I-pH yegazi lokugcoba kufanele ibe phakathi kuka-7.35 no-7.45. Izinguquko ezibalulekile ku-pH zingabonisa izinkinga ezisongela impilo okufanele ziphathwe ngokushesha. I-pH engama-6.9 ngokuvamile ibhekwa njengokuphela kwesiphetho sokushintsha kwe-pH.
- I-Carbon Dioxide (i-PCO2) : Inquma ukuthi umzimba wakho uyakwazi yini ukukhipha i-carbon dioxide ngokufanele noma uma i-carbon dioxide igcinwa ngumzimba.
- I-oksijeni (PO2) : Inquma uma amaphaphu akho akwazi ukuhambisa umoya-mpilo egazini lakho ngendlela efanele.
- I-Bicarbonate (HCO3) : Amazinga aphansi e-bicarbonate egazini angabonisa izinkinga ngezinso zezinso.
- I-Oxygen Saturation (O2) : Kulinganiswe ngesilinganiso se-0-100 lokhu kubonisa ukuthi oksijini okwenza kangakanani amathisini womzimba. Amaphesenti ayikhulu aphelele, futhi u-97% noma ngaphezulu kulindeleke ukuthi abe nomuntu onempilo. Ukwengezwa kwe-oksijeni kungadingeka kumazinga aphansi okugcwalisa.
I-ABG Ukuhumusha
Ukuhumusha imiphumela ye-ABG yinqubo eyinkimbinkimbi futhi kudinga amakhono aqinile emtholampilo ukuze acabangele isimo somuntu ngamunye. Into elula njengokuhlanza ingashintsha imiphumela, njengoba isimo se-lung sína noma esisongela impilo singabangela ushintsho ku-ABG ukuhlolwa.
Esikhathini sokubeka esibhedlela, le miphumela isetshenziselwa ukwenza izinguquko ezilungiselelweni zomoya noma ukucacisa ukuthi isiguli sidinga ukwesekwa kokuphefumula nge-ventilator noma oksijini. Imiphumela ingafaka:
I-Metabolic Acidosis : Eyaziwa nge-pH ephansi, amazinga e-bicarbonate aphansi kanye ne-carbon dioxide ephansi, lesi simo singabangelwa izinkinga zezinso, ukuphefumula ngokushesha noma ukuphefumula kakhulu.
I-alkalosis ye-metabolic : I-pH ephakanyisiwe, i-bicarbonate ne-carbon dioxide ngokuvamile ibonisa ukuhlanza okukhulu kuye kwashintsha imithi yegazi.
I-Acidosis Yokuphefumula : I-pH ephansi, i-bicarbonate ephakeme nephezulu kaboni dioxide ngokuvamile ibonisa isimo se-lung, njenge-pneumonia, noma isifo esifana ne-COPD. Kungabonisa isidingo sezinguquko zendiza uma isiguli sisevini.
I-alkalosis yokuphefumula : I-pH ephakeme, izinga eliphansi le-bicarbonate kanye ne-carbon dioxide elincane likhombisa ukuphefumula okusheshayo noma okujulile, njengokungathi uma uzwa ubuhlungu noma ngesikhathi sokuhlushwa kwe-hyperventilation. Kungabonisa isidingo sezinguquko zendiza uma isiguli sisevini.
Izwi kusuka
I-blood pressure egazini ingaba isilingo esiwusizo kakhulu, kodwa ukuchazwa kwalolu lwazi kungcono kushiywe ochwepheshe. Imiphumela eyoyethusa ngesiguli esisodwa ingase ibe yinto evamile komunye, futhi lemiphumela yokuhlola ingashintsha kabanzi kusuka ehoreni kuya kwehora ngokusekelwe ekungeneni kokuphefumula okufaka ukuhlinzeka ngezilungiselelo zomoya-mpilo noma i-ventilator.
Umhlinzeki wakho wezempilo kufanele akwazi ukukutshela ukuthi imiphumela yenzelwe yini futhi uma imiphumela ibonisa ukuthi isiguli sithuthukisa noma sidinga oksijithali noma ngisho nokusekelwa kwomoya.
