Hematocrit - akaderedza sandara, uye zvakawanda zvazvingava

Hematocrit ndiyo nhamba (chikamu) kuti erythrocytes kubva bhuku ropa (nhamba). indekisi ichi inoratidza nhamba yeplasma vhoriyamu uye matsvuku eropa vhoriyamu. Somuenzaniso, mumwe murwere ari mamiriro nehana, ungaderedza hematocrit haagoni kutora nzvimbo, apo semubairo nokurasikirwa neropa, nhamba matsvuku masero zvavo zvinogona kuderedzwa. Naizvozvo, iri kubva muzana haigoni kushandiswa, dzinoongorora mwero kupererwa neropa munguva yemberi iri pedyo pashure kuwedzerwa ropa kana kurasikirwa neropa.

Hematocrit angava yakaderera uye, kana ari kubatwa munhu akaidza murwere iri supine chinzvimbo. Refu compressive tourniquet tsinga inogona kuchengetwa zvenhema akakwidziridzwa mugumisiro. Venhema Low hematocrit zvingakonzerwawo nokuda dilution ropa. Izvi zvinoitika kana munhu ropa yokuenzanisira zvabviswa chete muzvidimbu yaiva zvikuru pakarepo pamberi intravenous aizomupa.

Kutsunga zviri chikamu masero matsvuku ropa yeplasma vhoriyamu uye ruvara paakati inobatsira iri nechirwere zvirwere zvakawanda, kunyanya kana vari ukama nokuchinja hemoglobin. Ndikati kuti siyanei Kuongorora Chizenga pamwero rinopa asina ruzivo zvikuru. Nokuyerwa chakarurama ichi pachiimbwa ine ruvara chokukomborerwa masero matsvuku eropa, uye hematocrit inopa uwane maonero ane ropa ezvinhu.

Somuenzaniso, pane muedzo neropa shoma hemoglobin. Zvinofanira kucherechedzwa kuti akadaro indekisi kungava nokuda kwezvikonzero zvakasiyana-siyana. The zvingakonzera kuita uye simbi kushaikwa kupererwa, uye kupererwa neropa chokuita zvemashiripiti ropa kana akakwidziridzwa hemolysis. Vapedza zvakawanda tsvakurudzo, unogona chakonzera kupererwa neropa angava kurasikirwa masero matsvuku eropa, uye mugumisiro wayo, ukuwo, - a akaderedza hematocrit. Nokududza ruvara indekisi, ziva kutyorwa ari kwetunhu hemoglobin. Izvi zvinobvumira kuti kusarudza chii chaizvoizvo kupererwa neropa: hyperchromic, hypochromic kana normochromic.

Normal hematocrit mune vakuru nevana, varume nevakadzi zvakasiyana. Saka, Somuenzaniso, zviri vaiona zvakajairika indekisi 33.0-44.5% nevanhu uye 38.0-49.0% vakadzi pakati makore makumi maviri namapfumbamwe.

Hematocrit nokuti kupererwa neropa riri dzinoratidzwa kuderedzwa izvo zvinokonzerwa vasanyanye kwenhamba erythrocytes. inoti izvi zviri zvakabatanidzwa, sezvinoita mutemo, pamwe nokurasikirwa neropa kana hemolysis. Hematocrit zvingava yakaderera uye mumamiriro ezvinhu zvinomutsa kuwedzera inzwi ropa. It rinopembererwa panguva pamuviri giperalbunemii kana munyu kushandiswa akawanda.

Ruvara vanoratidza inogona kuderedzwa pamwe vasanyanye Chizenga usage. Izvi zvinotisvitsa vasanyanye wevasungwa kuti Chizenga mumasero matsvuku. Akaderedza ruvara indekisi zvakare maitiro nokuti mugariro iyo zvinoderedza kukura erythrocytes kunoitika (microcytosis). Kuvandudza ruvara indekisi iri kuchengetwa macrocytosis. Muchiitiko chino, vakawedzera matsvuku eropa uye rine zvakawanda hemoglobin. Fani iyi kuchengetwa folate kushaikwa kupererwa, hypothyroidism, kugamuchira zvinodhaka cytotoxic.
