Ziziphi iindinganiso abazithetha ngazo ngokuhla kwe-hemoglobin?
Kuloo matyala xa uxinzelelo lwe-biological component egazini legazi lihlahla ngaphantsi kwe-110 g / l, kukho ukuphulwa. Ngaloo ndlela kumachiza wamukelwa ukunika ezinye izigaba. Xa ukuxinwa kwehla kwezantsi kwe-90 g / l, uhlobo oluqhelekileyo lwesifo luyaqala, kwaye ukususela ngo-70 g / l, le ngxaki ibhekiselwa kwisigaba esinzima.
Yintoni eyongela i-hemoglobin ephantsi ekukhulelwe?
Phakathi kweengxaki ezinokubambisana ezinxulumene ngqo nale nzekayo, kwindawo yokuqala ku-hypoxia ye-fetal. Ngenxa yokusilela kwesi sakhiwo seprotheni, inkqubo yokunikezelwa komzimba we-oxygen iphazamiseka. Izithuthi zenziwa ngokuthe ngqo yi-erythrocytes, ukugxininiswa kwento eyancipha ngenxa yokuntuleka kwe-hemoglobin. Kwiimeko ezininzi, ukungakwazi ukusebenza kweeseli zegazi kubangelwa ukuxinwa kwe-intsimbi ephantsi, okuyiyo ngqo kwi-hemoglobin.
Ukuba sithetha ngokuthe ngqo malunga ne-hemoglobin ephantsi efumanekayo kubasetyhini abakhulelweyo, ngu:
- Ukuphululwa kwenkqubo yokuphuhliswa kwe-intrauterine. Ngenxa yokusilela kwe-oksijeni, kukho ukungaphumeleli kwinkqubo yokukhula kunye nokubunjwa kwamalungu kwintsana.
- Ukuzalwa kwangaphambili. Kule meko, umngcipheko we- detachedment of placenta okanye i- detache ye-placenta iphakamileyo.
- Gestosis. Ingxaki enobungozi kakhulu yokukhulelwa, ehambelana ngokukodwa kunye nokuphulwa komzimba womama. Kukho ukuqala kwe-edema, iprotheni ifumaneka kumchamo, ukunyuswa kwegazi kuphuma. Kukho ukuphulwa kwesibindi.
Kwiimeko ezininzi, ukwehla kwe-hemoglobin ngexesha lokukhulelwa kulungele ukulungiswa ngokumisela amalungiselelo ensimbi, ukuthobela ukutya.
