Iigesi zegazi ezijikelezayo: yintoni, yintoni eyenzelwe yona kunye namaxabiso esalathiso

Umxholo

• Luqhutywa njani uviwo
• Yenzelwe ntoni
• Amaxabiso esalathiso
• Usiqonda njani isiphumo soviwo
• Uyintoni umahluko kwiigesi zegazi ezinobunzima kunye neentsholongwane

Uhlalutyo lwegesi yegazi luvavanyo lwegazi oluqhelekileyo olwenziwa kubantu abamkelweyo kwiCandelo loKhathalelo oluKhulu, olujolise ekuqinisekiseni ukuba ukutshintshiselana ngegesi kwenzeka ngokuchanekileyo kwaye ke, kuvavanya isidingo seoksijini eyongezelelweyo.

Ukongeza, luvavanyo olunokucelwa ngexesha lokulaliswa esibhedlele ukunceda ekuchongeni isifo sokuphefumla, sezintso okanye esosulelayo kakhulu, ukongeza ekuqinisekiseni ukuba ngaba unyango luyasebenza na, kwaye ke, lunokusetyenziswa njengenye yeendlela ezinokuthi nefuthe lokukhutshwa kwisigulana.

Luqhutywa njani uviwo

Uhlalutyo lwegesi yegazi lwenziwa ngokuqokelela isampulu yegazi kwimithambo yengalo okanye yomlenze. Olu hlobo lwengqokelela lubuhlungu kakhulu, kuba luyeyona ngqokelela ingenayo. Igazi eliqokelelweyo lisiwa elabhoratri kuvavanyo lwebhayoloji ukujonga i-pH yegazi, uxinzelelo lwe-bicarbonate kunye noxinzelelo oluncinci lwe-CO2.

Iiarterial gases zegazi azifanele ukwenziwa kwimeko yesifo esijikelezayo, njengoko kunokubakho ubunzima ekutsaleni igazi, ekunqandeni iingxaki okanye ukuba umntu usebenzisa ii-anticoagulants. Kwiimeko ezinjalo, ugqirha unokuyalela ezinye iimvavanyo ukuba zichonge izifo ezibangela utshintsho kwimiphunga.

Yenzelwe ntoni

Iigesi zegazi ezijikelezayo ziyacelwa ngugqirha ukuba:

• Jonga ukusebenza kwemiphunga, ngakumbi kuhlaselo lwesifuba okanye i-bronchitis kwaye kwimeko yokusilela kokuphefumla - Fumanisa ukuba zithini iimpawu zendlela kunye nokuphulukana nokuphefumla;
• Nceda vavanya i-pH kunye neasidi yegazi, eluncedo ekuncedeni ukufumanisa ukusilela kwezintso kunye necystic fibrosis, umzekelo;
• Vavanya i- ukusebenza kwemetabolism, ebalulekileyo ekuchongeni isifo sentliziyo, ukubetha (ukubetha) okanye uhlobo lweswekile II, umzekelo;
• Ukusebenza kwemiphunga emva kotyando okanye ukufakelwa. 

Ukongeza, uhlalutyo lwegesi yegazi luyacelwa kwakhona kwimeko yokonyuka kweziyobisi. Ukusebenza kolu vavanyo akuqhelekanga, akwenziwa kwiiklinikhi okanye kuthethwano oluqhelekileyo, kucelwa kuphela ngugqirha kwiimeko ezinzima kakhulu.

Amaxabiso esalathiso

Ixabiso eliqhelekileyo lohlalutyo lwegesi yegazi yile:

• pH: 7.35 - 7.45
• IBicarbonate: 22 - 26 mEq / L
• PCO2(uxinzelelo oluthile lwekhabhon diokside): 35 - 45 mmHg

Uvavanyo lwearterial yegazi lovavanyo lubonisa indlela esebenza ngayo imiphunga, oko kukuthi, ukuba utshintshiselwano ngegesi lwenziwa ngendlela echanekileyo, oko ke kubonisa imeko yomntu, enokuba sisifo seasidi okanye sokuphefumla okanye se-metabolic alkalosis. Qonda ukuba yintoni imetabolism kunye nokuphefumla i-acidosis, i-alkalosis ye-metabolic kunye ne-alkalosis yokuphefumula.

Usiqonda njani isiphumo soviwo

Itheyibhile elandelayo ibonisa imizekelo yexabiso eliguqukayo legesi yegazi:

Olu vavanyo alonelanga ukuvala ukuxilongwa, lubonisa kuphela ukuphefumla, ukuphazamiseka kwentliziyo okanye ukuphazamiseka komzimba, kunye nezinye iimvavanyo ezincedisayo, ezinje nge-X-ray, i-CT scan, olunye uvavanyo lwegazi kunye novavanyo lomchamo, zihlala zifunwa ngugqirha ukuze Ukuxilongwa kunokuvalwa kwaye unyango lunokuqaliswa ngokwendlela yotshintsho kuhlalutyo lwegesi.

Uyintoni umahluko kwiigesi zegazi ezinobunzima kunye neentsholongwane

Iiarterial gases zegazi zichonga amaxabiso ngqo e-oksijini nokuba izintso nemiphunga zisebenza ngokuchanekileyo na, ezinceda ekufumaniseni isifo semiphunga, izifo zezintso kunye nosulelo.

Uhlalutyo lwegesi yemithambo yegazi, kwelinye icala, lwenziwa njengokhetho lwesibini xa ukuqokelelwa emthanjeni kungenakwenzeka, ngokuqokelelwa okwenziwe emthanjeni, kwaye eyona njongo yayo iphambili kukunceda ekuchongeni izifo zesifo semithambo okanye ukujiya kwegazi iingxaki.
