Amagesi egazi e-arterial: kuyini, kuyini futhi kungamanani wesethenjwa

-Delile

• Kwenziwa kanjani ukuhlolwa
• Yenzelwe ini
• Amanani ayizethenjwa
• Uwuqonda kanjani umphumela wokuhlolwa
• Uyini umehluko emithanjeni yegazi egazini nemithambo yegazi

Ukuhlaziywa kwegesi emithanjeni yegazi ukuhlolwa kwegazi okuvame ukwenziwa kubantu abangeniswe e-Intensive Care Unit, okuhlose ukuqinisekisa ukuthi ukushintshaniswa kwegesi kwenzeka kahle futhi, ngaleyo ndlela, ukuhlola isidingo se-oxygen eyengeziwe.

Ngaphezu kwalokho, wukuhlolwa okungacelwa ngesikhathi sokulaliswa esibhedlela ukusiza ekutholeni izifo zokuphefumula, izinso noma izifo ezinzima, ngaphezu kokuqinisekisa ukuthi ukwelashwa kuyasebenza yini, ngakho-ke, kungasetshenziswa njengenye yezindlela thonya ukukhishwa esigulini.

Kwenziwa kanjani ukuhlolwa

Ukuhlaziywa kwegesi emithanjeni yegazi kwenziwa ngokuqoqa isampula yegazi emthanjeni wengalo noma womlenze. Lolu hlobo lweqoqo lubuhlungu impela, ngoba iqoqo elihlasela kakhulu. Igazi eliqoqiwe liyiswa elabhorethri ukuze lihlolwe ngamakhemikhali ukubheka i-pH yegazi, ukugxila kwe-bicarbonate kanye nengcindezi engaphelele ye-CO2.

Amagesi egazi emithanjeni akufanele enziwe uma kwenzeka kunesifo semithambo yegazi, ngoba kungahle kube nobunzima ekudwebeni igazi, ekunqandeni izinkinga noma uma umuntu esebenzisa ama-anticoagulants. Ezimweni ezinjalo, udokotela anga-oda ezinye izivivinyo ukukhomba izifo ezidala izinguquko zokuphefumula.

Yenzelwe ini

Amagesi egazi egazi aceliwe ngudokotela ukuthi:

• Hlola ukusebenza kwamaphaphu, ikakhulukazi ekuhlaselweni yisifuba somoya noma i-bronchitis futhi uma kwenzeka ukwehluleka ukuphefumula - Thola ukuthi ziyini izimpawu nokuthi ukwelashwa okuphefumulayo kuphathwa kanjani;
• Usizo hlola i-pH kanye ne-asidi yegazi, ewusizo ukusiza ukuxilongwa kokuhluleka kwezinso kanye ne-cystic fibrosis, isibonelo;
• Hlola i- ukusebenza kwe-metabolism, okubalulekile ekuboneni isifo senhliziyo, isifo sohlangothi (stroke) noma uhlobo lwesifo sikashukela sohlobo II, isibonelo;
• Ukusebenza kwamaphaphu ngemuva kwenqubo yokuhlinzwa noma ukufakelwa kabusha. 

Ngaphezu kwalokho, kucelwa nokuhlaziywa kwegesi egazini uma kwenzeka ukweqisa izidakamizwa. Ukusebenza kwalokhu kuhlolwa akuvamile, akwenziwa emitholampilo noma ekubonisaneni okujwayelekile, kucelwa kuphela udokotela ezimweni ezinzima kakhulu.

Amanani ayizethenjwa

Amanani ajwayelekile wokuhlaziywa kwegesi yegazi yile:

• pH: 7.35 - 7.45
• I-Bicarbonate: 22 - 26 mEq / L
• I-PCO2(ingcindezi eyingxenye yesikhutha): 35 - 45 mmHg

Ukuhlolwa kwegesi emithanjeni yegazi kukhombisa ukuthi amaphaphu asebenza kanjani, okungukuthi, uma ukushintshaniswa kwegesi kwenziwa ngendlela efanele, okukhombisa isimo somuntu, okungaba yi-acidosis noma i-alkalosis yokuphefumula noma ye-metabolic. Qonda ukuthi i-acidosis yemetabolism neyokuphefumula, i-alkalosis yemetabolism kanye ne-alkalosis yokuphefumula isho ukuthini.

Uwuqonda kanjani umphumela wokuhlolwa

Ithebula elilandelayo likhombisa izibonelo zamanani wegesi yegazi eguquliwe:

Lokhu kuhlolwa akwenele ukuvala ukuxilongwa, kuphakamisa kuphela ukuphazamiseka kokuphefumula, kwe-renal noma kwe-metabolic, nezinye izivivinyo ezihambisanayo, njenge-X-ray, i-CT scan, okunye ukuhlolwa kwegazi nokuhlolwa komchamo, kuvame ukucelwa ngudokotela ukuze ukuxilongwa kungavalwa futhi ukwelashwa kungaqalwa ngokuya ngesizathu soshintsho ekuhlaziyweni kwegesi egazini.

Uyini umehluko emithanjeni yegazi egazini nemithambo yegazi

Ama-arterial blood gases anquma amanani ngqo enani le-oxygen nokuthi izinso namaphaphu asebenza kahle yini, okusiza ekutholeni isifo samaphaphu, izifo zezinso kanye nezifo.

Ukuhlaziywa kwegesi emithambo yegazi, ngakolunye uhlangothi, kwenziwa njengenketho yesibili lapho ukuqoqwa emthanjeni kungenzeki, ngokuqoqwa kwenziwa emthanjeni, futhi inhloso yayo enkulu ukusiza ekutholeni izifo ezisemgogodleni noma ukuvaleka kwegazi izinkinga.
