Hematocrit landa - ukujonga ukuba eli nani yaye oko kuthetha ntoni

Xa enze uvavanyo lwegazi, ngokuqinisekileyo ziya kutsala amanani kunye amagama ebhalwe kwiphetshana esikhutshwe gqirha. Athetha ntoni? Umzekelo, hematocrit - ntoni na?

Igama elithi "hematocrit" linentsingiselo kabini. Kwelinye icala kukho isixhobo esilinganisa hematocrit, kwelinye icala oku isalathisi ngokwayo, apho iqashiso oogqirha malunga imeko yesigulane utsho.

Hematocrit - umlinganiselo iiseli igazi (iiseli ezibomvu ukuba kakhulu) ukuya ububomvu yayo. Ekubeni lowo kunye nezinga yesibini ilinganiswa kulo mzekelo ngeelitha, kwaye ixabiso hematocrit uya ilitha ilitha nganye.

Iindlela izigqibo hematocrit iiseli ezibomvu igazi wahluliwe plasma yegazi. Oku kwenziwa ngokusebenzisa centrifugation. Ngoko izixhobo icentrifuge igazi unwound ngesantya esiphezulu, nto leyo ekhokelela ekubeni alungise kwiindawo ezahlukeneyo iiseli ezahlukeneyo igazi kuxhomekeke koko babe ubunzima kunye mninzi. Ukumisela hematocrit kuvavanyo tube (sokukhetha umbala), nto leyo yahlulahlulwe nekhulu iziqu.

Phambi kokuba uthathe uvavanyo igazi, uvavanyo ityhubhu ahlambe kunye nesisombululo okhethekileyo. Emva koko isampuli yegazi yenziwe, kufuneka ube kwi ezilikhulu. Irabha ukhokho philisi ivaliwe baze bafakwe icentrifuge imizuzu asithoba ngesantya icentrifuge nesiqingatha amawaka. Ngeli xesha, iiseli ezibomvu phantsi koxinzelelo sobunzima zabo ezibekwe kwaye wenze inxalenye ethile kwityhubhu uvavanyo. Emva kokuba umatshini sele ugqityiwe umsebenzi wayo, ilabhoratri uthatha iselwa kwaye imisela - koko amngqonga iiseli ezibomvu. Inani iziphumo ziya kuba hematocrit.

Uhlalutyo ukujonga hematocrit kunzima kakhulu ngenxa yokuba kukho umngcipheko wokuba inani lobuxoki. Ngethuba lokwenza uphando kwafunyaniswa ukuba hematocrit kuxhomekeka kuthathwa ngayo igazi. Umzekelo, ukuba igazi kuthathwe isigulane silele phantsi, lo hematocrit nga lincitshiswe. Ukuba hematocrit leyo eziphakamileyo, oko kusenokubonisa ukuba iisampulu igazi sakhatshwa emthanjeni elide Urhintyelwe a tourniquet.

Hematocrit ilinganiselwa phantse kuzo zonke izigulane. Nangona kunjalo, kubalulekile ucinga ukuba eli nani kufunyaniswe iiseli ezibomvu kuphela, xa kungekho ndlela ezibonisa umgangatho yabo. Kodwa la manani usenokuba uthetha ukuba oogqirha malunga kwezinye izinto ezinxaxhileyo ebalulekileyo kwimpilo umguli. Ngokuqhelekileyo hematocrit impilo entle komntu akuxhomekekanga ekuzithandeleni yemeko ezisingqongileyo, ngoko ke bahlale uphawu olufanayo iminyaka emininzi. Ubulungisa, siphawula ukuba hematocrit uvuke kuphela utshintsho ubude (umz, climbers, iefa glubokovodnikov)

Eli zinga eyahlukileyo nakumantombazana ezahlukeneyo. Ngokomzekelo, into eyindoda kuthelekiswa hematocrit imazi inyusiwe - ukusuka obungamashumi amahlanu anesibini ekhulwini (ilitha litre liphindaphindwe nekhulu ukufumana ipesenti umfanekiso ngamnye). Xa abafazi nalo phakathi amashumi mathathu ezimashumi mane anambini ekhulwini. hematocrit engalinganiyo kunye nabantwana. Ngokuqhelekileyo kuzalwa yena ekhulwini ezilishumi ephezulu, kwaye besebancinane - ngezantsi. La manani kakhulu nokomzimba kwaye kubangela inkxalabo. Kodwa kuthekani ukuba hematocrit inyuswe? Kuthetha ntoni oku?

Ukwandisa hematocrit ukuze kwaziwe ukuba izinto ezininzi. Kuqala kwinto zonke, le ukwanda kwenani iiseli ezibomvu zegazi. Okwesibini, i hematocrit lungandiswa kwi imveliso elibomvu obukhulu kakhulu ngumzimba. Okwesithathu, ezinye izifo ezifana hypoxia, isifo sentliziyo, kwesisu isithintelo, emzimbeni, isifo sezintso kunokukhokelela ekubeni hematocrit ephakamileyo.

Ngenxa yoko, isalathisi ukuze lwaye kwicala ephantsi - oku kwenzeka xa kukho ilahleko igazi elikhulu, xa enxilile kakhulu amanzi, waphula umthetho ukuba umongo, igazi kunye nokuzalwa isisu.
