Hematocrit anda - indlela ukunquma lesi sibalo kanye ukuthi kusho

Lapho senza ukuhlolwa igazi, ngokuqinisekile ukuheha izinombolo kanye nemagama labhalwe ku ephepheni esikhishwe udokotela. Yini zazisho ukuthini? Ngokwesibonelo, hematocrit - kuyini?

Igama elithi "hematocrit" linencazelo double. Ngakolunye uhlangothi kuyinto ithuluzi ukuthi alinganise hematocrit, ngakolunye uhlangothi lena inkomba ngokwayo, okuyinto kusho okuningi ukuze odokotela ngesimo lesiguli.

Hematocrit - isilinganiso egazi (amangqamuzana abomvu egazi ngokwezinga elikhulu) ukuze akhishwe ububomvu yayo. Njengoba kokubili lowo ongcwelisayo nokukala yesibili ulinganiswa Kulokhu ngamalitha, futhi ukubaluleka hematocrit ngeke ilitha ilitha.

Izindlela yokunquma hematocrit kwamangqamuzana egazi abomvu ahlukaniswa oketshezini olungenambala lwegazi. Lokhu kwenziwa esebenzisa centrifugation. Ngakho igazi Centrifuge Izigaxa unwound ngesivinini, okuholela bazinze ezindaweni ezahlukene amaseli ahlukahlukene igazi kuye yilokho abanakho mass kanye kwabantu. Nquma hematocrit ekuhlolweni tube (pipette), okuyinto ihlukaniswe eziyikhulu iziqu.

Ngaphambi ukuthatha ukuhlolwa igazi, isivivinyo tube sihlanzwe isixazululo ekhethekile. Khona-ke igazi amasampuli uqhutshwa, kufanele kube ngezithuba nekhulu. Rubber kukakhokho capsule ivaliwe futhi ibekwe endaweni Centrifuge imizuzu ayisishiyagalolunye ngesikhathi Centrifuge ngesivinini nengxenye ayizinkulungwane. Phakathi nalesi sikhathi, le abomvu egazi ashaye ngaphansi ukucindezela isisindo sabo zixazululwe ngaphambi bese wenza ingxenye ethile e ngamapayipi ukuhlolwa. Ngemva umshini iqede umsebenzi wayo, laboratory ithatha umfuma futhi inquma - ngasiphi zibasile amangqamuzana abomvu egazi. Inombolo okuholela kuyoba hematocrit.

Ukuhlaziywa ukucacisa hematocrit kunzima ngempela ngenxa yokuthi kukhona ingozi inombolo yamanga. Phakathi nocwaningo kwatholakala ukuthi hematocrit kuxhomeke endleleni igazi esithathwayo. Ngokwesibonelo, uma igazi kuthathwa isiguli elele phansi, lo hematocrit zingancishiswa. Uma hematocrit liphakeme, kungase kubonise ukuthi le amasampula egazi kwakulandelwa umthambo eside abanjwe ngumuntu tourniquet.

Hematocrit kukalwa cishe zonke iziguli. Nokho, kuhle ukucabangela ukuthi lokhu sibalo quantifies ebomvu egazi kuphela, neze kubonise izinga yabo. Kodwa ngisho lezi zibalo kungenzeka ukukhuluma odokotela mayelana ezinye ngeziphambeko ebalulekile impilo isiguli. Ngokuvamile e hematocrit ezinhle kwezempilo akuxhomekile imvelo yangaphandle, ngakho-ke ungakwazi uhlale ku uphawu ofanayo iminyaka eminingi. Ukungakhethi, siphawula ukuthi hematocrit ongasukuma kuphela ushintsho ukuphakama (isib abaqwali, ababhukudi abangena glubokovodnikov)

Lokhu kulinganisela ihlukile ubulili ezahlukene. Ngokwesibonelo, owesilisa kuqhathaniswa hematocrit zesifazane anda - kusuka amane ukuze emashumi mahlanu anamibini amaphesenti (ilitha ilitha iphindwe eziyikhulu ukuthola sibalo iphesenti ngayinye). Ngo abesifazane kuba phakathi amathathu kuya amane nambili amaphesenti. hematocrit engalingani kanye nezingane. Ngokuvamile ewusana olusanda kuzalwa uphakeme amaphesenti ayishumi, futhi ngesikhathi isencane - ngezansi. Lezi zinombolo abasakwazi bokuphila hhayi sokukhathazeka. Kodwa kuthiwani uma hematocrit luyanda? Kusho ukuthini lokhu?

Ukwandisa hematocrit kungase isibaluli ezicini eziningana. Okokuqala, lokhu yokwanda kwenani kwamangqamuzana egazi abomvu. Okwesibili, hematocrit zingandiswa ukukhiqizwa okukhulu kakhulu egazi abomvu umzimba. Okwesithathu, ezinye izifo ezifana hypoxia, isifo senhliziyo, wamathumbu isimiso, ukuntuleka kwamanzi emzimbeni, isifo sezinso kungaholela yokuthi hematocrit ephakeme.

Ngakwelinye ihlangothi, inkomba kungenzeka sigudluke bebheke ephansi - lokhu kwenzeka uma igazi ukulahleka enkulu, lapho badakwe kakhulu amanzi, ephula umnkantsha, igazi kanye nokuzalwa isisu.
