Ukuminyana emithambo yegazi ekhanda - indlela aphile nalo

Ukwephula emithambo yegazi outflow amakhanda esikhathini sethu akuyona into engavamile. Akumangazi, ngoba abantu abaningi bachitha isikhathi esiningi esimweni ehlezi, ngokuvamile ikhanda lakhe phezu kwanoma iyiphi idokhumenti, incwadi noma notebook. Konke lokhu Yiqiniso, kuthinta outflow emithambo yegazi ekhanda.

Kodwa ngaphambi sikhuluma ngalokho ibonakala ukuminyana emithambo yegazi nendlela yokubhekana naso, udinga ukukhuluma kanjani ukwakha uhlelo kokuphakelwa kwegazi ebuchosheni. Kule ngxenye umzimba negazi ukhiphela ehlukile kuka kwezinye izitho. Yafika igazi labo lwemithambo, ingena kuma-capillary kwezicubu ezizungezile futhi unike i-oksijini kanye nezinye izinto ezidingekayo ingena ngemithambo cerebral ukuthi ingaphakathi cranial evulekile phakathi sinuses emithambo yegazi (itheku). ithambo kogebhezi ebusweni ubuchopho Lezi itheku kwakhiwa, ngakho umthamo yayo Awukwazi ukushintsha. Nokho, igazi ngokuvamile uthola ngokuphawulekayo esingaphansi bona angazamukela ngokwabo, ngakho umsebenzi wabo endaweni yokuqala ukuvimbela ukucinana emithambo yegazi ezimweni eziphuthumayo lapho igazi agelezela ubuchopho ngaphezulu kokujwayelekile.

Ngaphezu kwalezi amadivayisi, ukulawulwa ingcindezi wenziwa nezitsha palsy, okuyinto ebucayi kunoma ushintsho wegazi ukuphi. Ngokwesibonelo, lapho igazi eliningi ebuchosheni uthola ama-receptor ekhethekile phezu yegazi zithumela umlayezo kuya ebuchosheni, onikeza umyalo ukunweba inesikhala ka imithambo ethuthukisa outflow pooling eyeqile kwehlisa umfutho wegazi.

Kodwa ngaso sonke isikhathi kahle kakhulu emzimbeni zingazivumelanisa izinguquko izimo zangaphakathi. Ngezinye izikhathi stasis emithambo yegazi kungenzeka ngenxa yokuthi kwaphazamisa receptor ngenhla. Ngaphezu kwalokho, kunezinye izimbangela zokukhathazeka eziningi kahle amanzi emithambo yegazi: ukwephulwa ukukhanya zenzeka ngesikhathi kokuvivinya umzimba, kulesi sikhundla lisalele ngaphandle umcamelo, kuyilapho ecindezela collar entanyeni. ukwephulwa Heavy efanayo kwenzeka ezihlukahlukene izifo, ngandlela-thile okuhlobene esimiso senhliziyo nemithambo yegazi, izimila, ukulimala ekhanda nasemqaleni, ngisho nalapho engekho acinene ukuphefumula.

Izimpawu stasis emithambo yegazi kukhona ubuhlungu bekhanda njengoba njalo, isiyezi. Ngaphezu kwalokho, ubuhlungu bangaba matasa ngezinye ekugcwalisekeni isinyathelo, ushintsho izimo yangaphandle (lokushisa, umfutho womoya). Ezimweni ezimbi kakhulu, kungase kube niphele amandla, imisebenzi kahle ngokwengqondo, ugesi, epileptiform nokuquleka. Ngaphandle, lesi sifo bangase balwisane edema, cyanosis ebusweni, ububomvu esweni.

Ngenxa yalesi sici, ukuminyana emithambo yegazi ekhanda cishe neze isifo primary, futhi ngokuvamile comorbidity. Ngakho-ke kubalulekile ukuze kuhlonzwe ukucacisa lokho, yini zokugula yikho okuyimbangela yenkinga, ukuze bakwazi ukuba linqume ukwelashwa lesifanele. Ngaphezu kwalokho, kubalulekile ukuba acabangele izici zangaphandle, okungase kubangele stasis emithambo yegazi. Ukwelashwa, ngakho-ke, ihlose silwe a zokugula ukuthi kungabangela yokujama tsi. Nokho, ukuze kube lula isimo lesiguli ingasetshenziswa izindlela ezihlukahlukene, ekubuyiseleni evamile ukugeleza kwegazi.
