Uvavanyo lwegazi lwe-CO2

I-CO2 yicarbon dioxide. Eli nqaku lixoxa ngovavanyo lwaselebhu ukulinganisa umyinge wekhabhon dayokisaidi engamanzi egazini lakho, ebizwa ngokuba yidum.

Emzimbeni, uninzi lwe-CO2 lukwimo yento ebizwa ngokuba yi-bicarbonate (HCO3-).Ke ngoko, uvavanyo lwegazi lwe-CO2 linyani yenqanaba lakho le-bicarbonate yegazi.

Isampulu yegazi iyafuneka. Uninzi lwexesha igazi litsalwa kumthambo ngaphakathi kwengqiniba okanye ngasemva kwesandla.

Amayeza amaninzi anokuphazamisa iziphumo zovavanyo lwegazi.

• Umboneleli wakho wokhathalelo lwempilo uya kukuxelela ukuba ngaba ufuna ukuyeka ukuthatha nawaphi na amayeza phambi kokuba wenze olu vavanyo.
• SUKUYEKE okanye utshintshe amayeza akho ungakhange uthethe nomboneleli wakho kuqala.

Unokuziva iintlungu okanye ulwamvila xa kufakwa inaliti. Unokuziva ubethwa sisiza emva kokuba kuthathwe igazi.

Uvavanyo lwe-CO2 luhlala lwenziwa njengenxalenye ye-electrolyte okanye iphaneli esisiseko ye-metabolic. Utshintsho kwinqanaba lakho le-CO2 linokucebisa ukuba ulahlekelwe okanye ugcine ulwelo. Oku kunokubangela ukungalingani kwii-electrolyte zomzimba wakho.

Amanqanaba e-CO2 egazini achaphazeleka ngumsebenzi wezintso kunye nemiphunga. Izintso zinceda ukugcina amanqanaba aqhelekileyo e-bicarbonate.

Uluhlu oluqhelekileyo ngama-23 ukuya kuma-29 eemilliequivalents kwilitha nganye (mEq / L) okanye ngama-23 ukuya kuma-29 eemilimitha ngelitha (mmol / L).

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Thetha nomboneleli wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Umzekelo ongentla ubonisa uluhlu lwemilinganiselo eqhelekileyo yeziphumo zolu vavanyo. Ezinye iilabhoratri zisebenzisa imilinganiselo eyahlukeneyo okanye zinokuvavanya iisampulu ezahlukeneyo.

Amanqanaba angaqhelekanga anokubangelwa zezi ngxaki zilandelayo.

Amanqanaba asezantsi kunesiqhelo:

• Isifo iAddison
• Urhudo
• Ityhefu ye-ethylene glycol
• Ketoacidosis
• Isifo sezintso
• Lactic acidosis
• I-metosis acidosis
• Ityhefu yeMethanol
• I-acidosis ye-tubular acidosis; kude
• I-acidosis ye-tubular acidosis; proximal
• I-alkalosis yokuphefumula (iyahlawulwa)
• I-Salicylate toxicity (njenge-aspirin overdose)
• Ukuphambuka kwethambo

Amanqanaba aphezulu kunalawo aqhelekileyo:

• Isifo seBartter
• Isifo seCushing
• Hyperaldosteronism
• I-alkalosis yeMetabolic
• I-acidosis yokuphefumla (iyahlawulwa)
• Ukuhlanza

I-Delirium inokutshintsha amanqanaba e-bicarbonate.
