Yiziphi izindinganiso abazisho ngokuncipha kwe-hemoglobin?
Kulezo zimo lapho ukuhlanganiswa kwesakhiwe se-biological esinikezwa ngamangqamuzana egazi kwehla ngaphansi kuka-110 g / l, kukhona ukwephulwa. Ngakho-ke emithini yokwelashwa yamukelwa ukunikeza ezinye izigaba. Lapho ukuhlushwa kwehla ngaphansi kwe-90 g / l, uhlobo olujwayelekile lwesifo luqala, futhi kusukela ngo-70 g / l, lesi sifo sibhekiswe esigabeni esinzima.
Yini eyongela i-hemoglobin ephansi lapho ekhulelwe?
Phakathi kwezinkinga ezikhona zokubeletha ezihlobene ngqo nalezi zenzakalo, okokuqala yi-hypoxia ye-fetal. Ngenxa yokuntuleka kwalesi sakhiwo samaprotheni, inqubo yokulethwa komzimba wengane yomoya iphazamiseka. Ezokuthutha zenziwa ngqo yi-erythrocytes, okuhlushwa kwayo okuye ngenxa yokuntuleka kwe-hemoglobin. Ezimweni eziningi, ukungasebenzi kwamangqamuzana egazi kungenxa yokuhlushwa kwe-iron okuphansi, okuyiyo ngqo kwe-hemoglobin.
Uma sikhuluma ngokuqondile nge-hemoglobin ephansi esitholakala kubesifazane abakhulelwe, yilokhu:
- Ukuphulwa kwenqubo yokuthuthukiswa kwe-intrauterine. Ngenxa yokuntuleka kwe-oksijeni, kukhona ukwehluleka kwenqubo yokukhula nokwakhiwa kwezitho ezinganeni.
- Ukuzalwa kwangaphambi kwesikhathi. Kule nkinga, ingozi yokuthungatha isikhathi esingaphansi kwe-placenta noma inqola engasese ye-placenta iphezulu.
- I-Gestosis. Ingxabano eyingozi kunazo zonke yokukhulelwa, ehlobene ngokuyinhloko nokuphulwa emzimbeni kamama. Kukhona ukuqala kwe-edema, iphrotheni itholakala emcinini, ukucindezeleka kwegazi kuphakama. Kukhona ukwephulwa kwesibindi.
Ezimweni eziningi, ukwehla kwe-hemoglobin ngesikhathi sokukhulelwa kulungiswa ukulungiswa ngokubeka amalungiselelo ensimbi, ukunamathela ekudleni.
