Kuyini ukuhlolwa kwezinga le-oxygen oxygen?

Ukuhlolwa kwezinga le-oksijini egazini, okwaziwa nangokuthi ukuhlaziywa kwegesi yegazi, kukala inani le-oxygen ne-carbon dioxide egazini. Uma uphefumula, amaphaphu akho adonsa umoya (ahogele) umoya-mpilo futhi aphefumulele ngaphandle (awukhiphe) isikhutha. Uma kunokungalingani emazingeni e-oxygen ne-carbon dioxide egazini lakho, kungasho ukuthi amaphaphu akho awasebenzi kahle.

Ukuhlolwa kwezinga le-oksijini egazini kubheka nokulinganisela kwama-acid nezisekelo, ezaziwa njenge-pH balance, egazini. I-asidi eningi noma incane egazini ingasho ukuthi kunenkinga ngamaphaphu akho noma izinso.

Amanye amagama: ukuhlolwa kwegesi yegazi, imithambo yegazi yegazi, i-ABG, ukuhlaziywa kwegesi yegazi, ukuhlolwa komoya we-oxygen

Kusetshenziselwa ini?

Ukuhlolwa kwezinga le-oksijini yegazi kusetshenziselwa ukubheka ukuthi amaphaphu akho asebenza kahle kangakanani futhi ulinganise ibhalansi ye-acid-base egazini lakho. Isivivinyo ngokuvamile sifaka izilinganiso ezilandelayo:

• Okuqukethwe kwe-oksijeni (O2CT). Lokhu kukala inani le-oxygen egazini.
• Ukugcwaliswa komoya-mpilo (O2Sat). Lokhu kukala inani le-hemoglobin egazini lakho. IHemoglobin yiprotheni kumaseli akho abomvu egazi athwala umoya-mpilo osuka emaphashini wakho uye kuwo wonke umzimba wakho.
• Ukucindezela okuncane kwe-oxygen (PaO2). Lokhu kukala ingcindezi yomoya-mpilo oncibilikiswe egazini. Kuyasiza ukukhombisa ukuthi umoya-mpilo usuka kanjani emaphashini akho uye egazini lakho.
• Ukucindezela okuncane kwe-carbon dioxide (PaCO2). Lokhu kukala inani le-carbon dioxide egazini.
• pH. Lokhu kukala ibhalansi ye-acid nezisekelo ezisegazini.

Kungani ngidinga ukuhlolwa kwezinga le-oxygen?

Kunezizathu eziningi lokhu kuhlolwa kuyalwa. Ungadinga ukuhlolwa kwezinga leoksijini egazini uma:

• Unenkinga yokuphefumula
• Yiba nezikhathi zokuhlanza kanye / noma ukuhlanza kaningi
• Belashwa isifo samaphaphu, esifana nesifuba somoya, isifo esingamahlalakhona sokuphazamiseka kwamaphaphu (COPD), noma i-cystic fibrosis. Ukuhlolwa kungasiza ukubona ukuthi ukwelashwa kuyasebenza yini.
• Muva nje ulimaze ikhanda noma intamo yakho, okungathinta ukuphefumula kwakho
• Kwakudingeka ukweqisa izidakamizwa
• Bathola ukwelashwa komoya-mpilo ngenkathi basesibhedlela. Ukuhlolwa kungasiza ekuqinisekiseni ukuthi uthola inani elifanele le-oxygen.
• Yiba nobuthi be-carbon monoxide
• Yiba nokulimala kwentuthu yokuphefumula

Ingane esanda kuzalwa nayo ingadinga lokhu kuhlolwa uma inenkinga yokuphefumula.

Kwenzekani ngesikhathi sokuhlolwa kwezinga le-oxygen?

Ukuhlolwa kwegazi okuningi kuthatha isampula emthanjeni. Kulesi sivivinyo, umhlinzeki wezokunakekelwa kwempilo uzothatha isampula yegazi emthanjeni. Lokho kungenxa yokuthi igazi elivela emthanjeni linamazinga aphezulu e-oxygen kunegazi elivela emthanjeni. Isampula ivame ukuthathwa emthanjeni ongaphakathi kwesihlakala. Lokhu kubizwa ngokuthi yi-radial artery. Kwesinye isikhathi isampuli ithathwa emthanjeni endololwaneni noma emgodini. Uma usana olusanda kuzalwa luhlolwa, isampula ingathathwa esithendeni somntwana noma enkabeni yomntwana.

Ngesikhathi senqubo, umhlinzeki wakho uzofaka inaliti enomjovo emthanjeni. Ungase uzwe ubuhlungu obunzima njengoba inaliti ingena emthanjeni. Ukuthola isampula yegazi emthanjeni kuvame ukuba buhlungu kakhulu kunokuthola igazi emthanjeni, uhlobo oluvame kakhulu lwenqubo yokuhlolwa kwegazi.

Lapho isipetu sesigcwele igazi, umhlinzeki wakho uzofaka ibhandishi endaweni yokubhoboza. Ngemuva kwale nqubo, wena noma umhlinzeki kuzodingeka ukuthi nisebenzise ingcindezi eqinile kuleyo ndawo imizuzu engu-5-10, noma ngisho nangaphezulu uma nisebenzisa umuthi wokunciphisa igazi.

Ngabe kukhona engizodinga ukukwenza ukulungiselela isivivinyo?

Uma isampuli yakho yegazi ithathwa esihlakaleni sakho, umhlinzeki wakho wezokunakekelwa kwempilo angenza ukuhlolwa kokujikeleza okubizwa ngokuthi ukuhlolwa kuka-Allen ngaphambi kokuthatha isampula. Ekuhlolweni kwe-Allen, umhlinzeki wakho uzofaka ingcindezi emithanjeni engalweni yakho amasekhondi ambalwa.

Uma ukwelashwa komoya-mpilo, i-oxygen yakho ingavalwa cishe imizuzu engama-20 ngaphambi kokuhlolwa. Lokhu kubizwa ngokuthi ukuhlolwa kwegumbi lomoya. Lokhu ngeke kwenziwe uma ungakwazi ukuphefumula ngaphandle komoya-mpilo.

Ingabe zikhona izingozi esivivinyweni?

Kunengozi encane kakhulu yokuhlolwa izinga leoksijini legazi. Kungenzeka uphume igazi, ulimale, noma ube buhlungu lapho kufakwe khona inaliti. Yize izinkinga zingavamile, kufanele ugweme ukuphakamisa izinto ezisindayo amahora angama-24 ngemuva kokuhlolwa.

Isho ukuthini imiphumela?

Uma imiphumela yakho yezinga le-oksijeni egazini ingejwayelekile, kungasho ukuthi:

• Abathathi i-oxygen eyanele
• Abalahli i-carbon dioxide eyanele
• Yiba nokungalingani emazingeni akho e-acid-base

Lezi zimo zingaba yizimpawu zesifo samaphaphu noma sezinso. Ukuhlolwa akukwazi ukuxilonga izifo ezithile, kodwa uma imiphumela yakho ingejwayelekile, umhlinzeki wakho wezokunakekelwa kwempilo uzo-oda izivivinyo eziningi ukuqinisekisa noma ukukhipha ukuxilongwa. Uma unemibuzo ngemiphumela yakho, khuluma nomhlinzeki wakho wezokunakekelwa kwempilo.

Funda kabanzi mayelana nokuhlolwa kwelabhorethri, ububanzi bezinkomba, nemiphumela yokuqonda.

Ngabe kukhona okunye engidinga ukukwazi ngokuhlolwa kwezinga leoksijini egazini?

Olunye uhlobo lokuhlola, olubizwa ngokuthi i-pulse oximetry, nalo luhlola amazinga e-oxygen egazini. Lokhu kuhlolwa akusebenzisi inaliti noma kudinga isampula yegazi. Ku-pulse oximetry, ithuluzi elincane elifana nesiqeshana elinenzwa ekhethekile linamathiselwe eminweni yakho, kuzwane, noma endlebeni. Njengoba idivayisi ilinganisa i-oxygen "peripherally" (endaweni engaphandle), imiphumela inikezwa njenge-peripheral oxygen saturation, eyaziwa nangokuthi yi-SpO2.
