Hematocrit - yafupika mlingo, ndi mlingo kuchuluka

Hematocrit ndi chiwerengero (kuchuluka) wa erythrocytes kwa buku magazi (okwana). index amasonyeza chiŵerengero cha madzi voliyumu ndi wofiira buku maselo a magazi. Mwachitsanzo, ngati wodwala amene ali mu mkhalidwe mantha, utachepa hematocrit simungakhoze kutenga malo, pamene chifukwa cha kutaika kwa magazi, chiwerengero cha maselo a magazi ambiri angathe kuchepetsedwa. Choncho, kuchuluka sangathe ntchito, potaya mlingo wa magazi m'thupi posachedwapa pambuyo magazi kapena kutaya magazi.

Hematocrit kungakhale m'munsi, ndipo ngati mu adani zofufuza wodwala mu malo supine. Yaitali compressive tourniquet mtsempha zingaoneke chifukwa monama m'mwamba. Onyenga Low hematocrit angakhalenso chifukwa dilution wa magazi. Izi zimachitika pamene nyemba magazi wachotsedwa nthambi chomwecho, chimene chinali ndithu asanalankhule kulowetsedwa mtsempha.

Khama la kuchuluka kwa maselo a magazi buku plasma ndi mtundu chizindikiro wothandiza matenda a matenda ambiri, makamaka ngati zokhudzana ndi kusintha hemoglobin. Ine ndiyenera kunena kuti kusanthula osiyana ndi mlingo hemoglobin amapereka si nkhani zochuluka. Muyeso wa chizindikiro ichi molumikizana ndi chizindikiro mtundu maselo a magazi, ndipo hematocrit imapereka view mwatsatanetsatane za chikhalidwe magazi.

Mwachitsanzo, pali magazi ndi kuchepetsedwa hemoglobin. Tikumbukenso kuti zimenezi index mwina chifukwa zifukwa zosiyanasiyana. zinthu akhoza kuchita ndi akusowa chitsulo magazi m'thupi, ndi magazi m'thupi kugwirizana ndi magazi zamatsenga kapena kukwezeka hemolysis. Nditakhala kufufuza zambiri, mukhoza kupeza chifukwa cha magazi mwina imfa maselo a magazi, ndipo zotsatira zake, motero, - maola hematocrit. KUFOTOKOZERA mtundu index, kudziwa kuyan'anila mu kaphatikizidwe wa hemoglobin. Zimenezi zimathandiza kudziwa zimene kwenikweni kwa magazi m'thupi: hyperchromic, hypochromic kapena normochromic.

Normal hematocrit akuluakulu ndi ana, amuna ndi akazi osiyana. Mwachitsanzo, anthu amaona kuti yachibadwa index 33.0-44.5% amuna ndi 38.0-49.0% kwa akazi a zaka zapakati pa zaka makumi awiri ndi anayi ndi makumi awiri.

Hematocrit kwa magazi m'thupi amakhala ndi wotsikirapo amene amayambitsidwa ndi kuchepa kwa chiwerengero cha erythrocytes. limati izi ogwirizana, monga ulamuliro, ndi kutaya magazi kapena hemolysis. Hematocrit kungakhale m'munsi ndi zinthu kumaputa kuwonjezeka mu buku magazi. Izo chikondwerero pa mimba giperalbunemii kapena mchere ntchito lalikulu zedi.

Chionetsero mtundu mwina kuchepetsedwa ndi kuchepa hemoglobin kaphatikizidwe. Zimenezi zimabweretsa kuchepa mu ndende ya hemoglobin maselo ofiira a magazi. Yafupika mtundu index ndi khalidwe la chikhalidwe imene kuchepetsa kukula kwa erythrocytes kumachitika (microcytosis). Kuwonjezera mtundu index zimawonedwa mu macrocytosis. Pankhaniyi, kuchuluka Selo lofiira la magazi ndi lili hemoglobin kwambiri. zodabwitsazi zimawonedwa mu folate akusowa magazi m'thupi, hypothyroidism, kulandira mankhwala cytotoxic.
