Vana kazhinji vanofanira kupa ropa kuti vaongorore. Izvi zvakakosha, sezvo maumbirwo emagetsi eropa ari nguva dzose uye kuchinja kwaro kwakasiyana-siyana, panguva ipi zvayo chirwere, zvine chinhu chinokosha chokuongorora.
Chii chinonzi hematocrit?
Zvinonyatsozivikanwa kuti ropa revanhu rinoumbwa nehutano-erythrocytes, leukocytes uye maplatelet. Nokudaro, mune urongwa hwehuwandu hwekuongorora ropa kune chiratidzo chakakosha sehematocrit. Inoratidza hutano hwe erythrocytes muropa romwana, nokuti inoumba huwandu hwemagetsi emagetsi. Kazhinji, nhamba ye hematocrit inoratidzirwa semapurogiramu ehuwandu hweropa.
Ko hematocrit inotorwa sei?
Mune girasi rinokosha remukati nemutengo wekuparadzaniswa, iyo inonziwo hematocrit, inodururira zvishoma ropa. Mushure meizvozvo, inoiswa mu centrifuge. Pasi pechiito chekuvhenekera, erythrocyte dzinokurumidza kusvika pasi, shure kwazvo zviri nyore kuti uone kuti chikamu cheropa chinoumba chii. Zvinofanira kuonekwa kuti vanotsvedzesa vanotsvaga vava kunyanya kushandiswa mumakorikari emazuva ano ekurapa kuti vaone nhamba ye hematocrit.
Hematocrit ndiyo inowanzo muvana
Muvana, chirevo chekukosha ichi chinoenderana nezera:
- mwana achangoberekwa - 44-62%;
- kubva pakuzvarwa kusvika kumwedzi mitatu - 32-44%;
- kubva pamwedzi mitatu kusvika kune imwe gore - 36-44%;
- kubva pagore rimwe kusvikira pamakore 10 - 37-44%.
Hematocrit yakaderera mumwana - chikonzero
Kubva pane tsanangudzo, tinogona kufungidzira kuti kukosha kwehematocrit kunoderera nekuderera kwenhamba ye erythrocytes muropa romwana. Iyo hematocrit inonzi inoderedzwa pa20-25% uye izvi zvinogona kushandiswa nekuvapo kwemamwe matambudziko:
- kunonoka kuumbwa kwe erythrocytes mumufupa wemapfupa;
- kuwedzera mumwero wekuparadzwa kwe erythrocytes muropa;
- kuwedzerwa ropa ropa mumwana;
- kuwedzera muhuwandu hweprotini muropa (hyperproteinemia);
- ropa rakatetepa (hyperhydration);
- kubuda ropa kukuru;
- anemia.
Zvinofanira kuonekwa kuti chiratidzo chimwechete chehematocrit hachikwanise kutaura zvakarurama pamusoro pekuvapo kwezvinetso mumumwana wemwana. Kuti uwane mufananidzo wakajeka, chiratidzo ichi muhutachiwana hwehutachiwana chinosanganiswa nehuwandu hweHemoglobin. Asi zvisinei, kuitira kuti zviongororwe zvakajeka, chero zvakadaro, zvakakosha kuti uongorore zvakanyatsorongororwa uye uone chii chakaita kuti kudonhedzwa muhuwandu hwemasero matsvuku eropa muropa.
