Kuyini ukuvaleka kwemithambo yegazi? Ake sixoxe ngakho kalula!

Wake wazibuza ukuthi kungani imithambo yegazi emzimbeni wakho ngezinye izikhathi iba mikhulu futhi ngezinye izikhathi ibe mincane? Lokhu kukhula kwemithambo yegazi yilokho esikubiza ngokuthi `(Vasodilation)` kwisayensi yezokwelapha. Nakuba lokhu kuyinto evamile eyenzeka emizimbeni yethu ngaso sonke isikhathi, ngezinye izikhathi kungabangela izinkinga ezinkulu. Ngakho-ke, ake sifunde ukuthi iyini ngempela `(Vasodilation)` namuhla, akunjalo?

Kuyini ngempela `(i-Vasodilation)`? Lokhu kwenzeka kanjani?

Kalula nje, "i-Vasodilation" iwukwanda kwemithambo yegazi emzimbeni wakho. Uma le mithambo yegazi ikhula, igazi eliningi ligeleza kuyo. Lokhu kwehlisa umfutho wegazi lakho. Lokhu kuyinto eyenzeka ngaphakathi emzimbeni wakho ngaso sonke isikhathi, noma ungaqapheli.

Manje, bheka umsebenzi wegazi emizimbeni yethu. Igazi lethu yilona elithwala umoya-mpilo nezakhamzimba emzimbeni, futhi lisiza nokulawula izinga lokushisa lomzimba.

Ngakho-ke le mithambo yegazi ayiwona nje amapayipi. Inezingqimba zemisipha. Le misipha yiyo enquma ukuthi imithambo yegazi kufanele ivuleke nini nokuthi kufanele inciphe nini. Uma imithambo yegazi ikhula kanje, sikubiza ngokuthi `(Vasodilation)`. Olunye uhlangothi lwalokhu, lapho imithambo yegazi incipha, lubizwa ngokuthi `(Vasoconstriction)`. Uyaqonda?

Kunini lapho lokhu `(i-Vasodilation)` kwenzeka khona ngokwemvelo?

Lezi zinto kungenzeka ukuthi zenzeke nakuwe, bheka lezi zibonelo:

• Uma uzizwa unamahloni, ubuso bakho buphenduka bubomvu, akunjalo? Ngaleso sikhathi, ubuso bakho buzizwa bushisa kancane, ngoba imithambo yegazi emincane engaphansi kwesikhumba sakho, esiyibiza ngokuthi "ama-capillaries", iba "i-vasodilated." Bese ukugeleza kwegazi ebusweni bakho kuyanda. Kufana nengane encane enamahloni.
• Uma ungena ebhavini elishisayo: Uma nje ungena emanzini ashisayo, ama-capillary emzimbeni wakho aqala ukuvuleka. Lokhu kwenzelwa ukulawula ukushisa okungazelelwe okunqwabelana emzimbeni wakho futhi kukusize uhlale ufudumele. Kodwa-ke, yingakho kungakuhle ukuhlala emanzini ashisayo isikhathi eside kakhulu. Uma wenza kanjalo, umfutho wegazi lakho ungehla kakhulu futhi ungase uphelelwe amandla. Ngakho-ke qaphela!
• Uma uzivocavoca: Uma uzivocavoca kanzima, ugijima, noma ugxuma, amangqamuzana omzimba wakho, ikakhulukazi amangqamuzana emisipha, adinga umoya-mpilo kanye nezakhamzimba ngokushesha. Ngemuva kwalokho imithambo yegazi iyavuleka bese ithumela igazi eliningi ukuze kuhlangatshezwane naleso sidingo.
• Uma kwenzeka ukutheleleka emzimbeni: Ake sithi unenxeba endaweni ethile emzimbeni wakho eliqale ukubola. Uma kwenzeka ukutheleleka okunjalo, umzimba wethu usabela ngokwandisa ukugeleza kwegazi endaweni ethelelekile. Lokhu kwenza kube lula ngomzimba ukulwa nokutheleleka nokulungisa umonakalo obangelwe yiwo.

Ingabe izinto esizidlayo nesiziphuzayo zingadala "i-Vasodilation"?

Yebo, kungenzeka ngempela. Ezinye zezinto esizidlayo nesiziphuzayo zingabangela ukuthi imithambo yegazi ivuleke futhi yehlise umfutho wegazi. Bheka:

• Ukudla okunama-nitrate amaningi:Imifino eluhlaza enamaqabunga njengespinashi, ilethisi, ama-radishes, kanye ne-bok choy igcwele ama-nitrate. Imizimba yethu iguqula ama-nitrate abe yikhemikhali ebizwa ngokuthi i-nitric oxide. I-nitric oxide iyindlela enhle yokwandisa imithambo yegazi.
• Utshwala: Uma nje uphuza utshwala obuncane, i-"Vasodilation" nayo iyenzeka emzimbeni. Yingakho abanye abantu behlanza igazi uma bephuza utshwala. Kodwa lokhu kungokwesikhashana. Ngemva kwesikhathi esithile, umfutho wegazi ubuyela esimweni esijwayelekile. Kodwa khumbula, uma uphuza utshwala obuningi, umfutho wegazi wakho uzokhuphuka. Lesi yisona sizathu esiyinhloko esenza odokotela beluleke ngokuphuza utshwala obuningi.

Ingabe ikhona imithi ebangela "i-vasodilation"?

Zikhona, ziningi. Eminye imithi yenzelwe ukubangela "i-Vasodilation." Lokhu kwenzeka futhi njengomphumela ongemuhle weminye imithi.

• Imithi yokucindezeleka kwegazi: Imithi eminingi yokucindezeleka kwegazi isebenza ngokwandisa imithambo yegazi. Yilowo msebenzi oyinhloko waleyo mithi.
• I-Nitroglycerin: Lokhu futhi kuyi-vasodilator eyaziwayo. Isetshenziselwa ukwelapha ukuhlaselwa yinhliziyo kanye nobuhlungu besifuba, okwaziwa nangokuthi i-angina.
• Imithi yokungasebenzi kahle kwenduku: Imithi efana ne-Sildenafil (eyaziwa nangokuthi i-Viagra®) isebenza ngokwandisa ukugeleza kwegazi endodeni. Le mithi ikhulisa ukugeleza kwegazi kuya endodeni.

Yini okufanele uyenze uma umfutho wegazi wehla kakhulu ngenxa ye-`(Vasodilation)`?

Uma umfutho wegazi wakho wehla kakhulu ngenxa yokwanda kwemithambo yegazi, okubizwa ngokuthi i-hypotension, kunezindlela eziningana zokuyelapha. Lokhu kuvame ukwenzeka esibhedlela.

• Ukuvuselela uketshezi: Lokhu kuhilela ukunikeza uketshezi, njengosawoti, emthanjeni (uketshezi lwe-IV). Lokhu kwandisa inani loketshezi emzimbeni futhi kusiza ukuphakamisa umfutho wegazi.
• Imithi yokucindezela kwegazi: Kunezinhlobo ezimbili zemithi, ``Vasoconstrictors'' kanye ``Vasopressors'', ezisetshenziselwa ukwelapha umfutho wegazi ophansi. Le mithi isebenza ngokubangela ukuba imithambo yegazi evulekile inciphe (vasoconstriction), okubuyisela umfutho wegazi esimweni esijwayelekile.

Ingabe `(i-Vasodilation)` ingaba yingozi?

Yebo, kwezinye izimo lokhu kungaba yingozi. Kuncike embangela "ye-Vasodilation", ukuthi kwenzeka nini, kanye nobunzima bayo. Kwezinye izimo ezimbi kakhulu, ukwanda kwemithambo yegazi (kanye nezimpawu ezihambisana nayo) kungaba yingozi ngisho nokuphila.

Cabanga ngalokhu: Ezimweni ezisongela ukuphila njengalesi, `(i-Vasodilation)` nayo iyimbangela:

• Ukusabela okukhulu kwe-allergy:Lokhu kubizwa nangokuthi `(Anaphylaxis)`. Lokhu kwenzeka lapho isimiso somzimba sokuzivikela sisabela kakhulu entweni ethile (isib. ukudla, imithi, ukulunywa yizinambuzane) kangangokuthi kungaba yingozi. Lapho `(Anaphylaxis)` kwenzeka, umuntu uba `(shock)`, `(blood pressure)` yehla ngendlela eyingozi, futhi imigudu yokuphefumula iyavaleka, okwenza kube nzima ukuphefumula. Umuthi `(Epinephrine)` onikezwa esimweni esiphuthumayo esinjalo uyi-`(vasoconstrictor) enamandla. Okusho ukuthi, uphakamisa `(blood pressure)` futhi, usiza ukwenza ukuphefumula kube lula, futhi unciphise impendulo yomzimba.
• Ukushaqeka kwe-Septic: I-Sepsis yisimo esisongela ukuphila lapho umzimba usabela kakhulu ekuthelelekeni kangangokuthi kungaba yingozi empilweni. Ukushaqeka kwe-Septic kuyindlela embi kakhulu (futhi engase ibulale) yalesi simo. Kulesi simo, umfutho wegazi wehla kakhulu ngenxa yokuvuleka kwegazi (ukwanda kwemithambo yegazi emzimbeni wonke). Esimweni esibucayi kangaka, uketshezi lwe-IV kanye nemithi yokwandisa umfutho wegazi kubalulekile ukusindisa impilo yomuntu.

Kufanele ubonane nini nodokotela mayelana `(i-Vasodilation)`?

Esikhathini esiningi, i-`(Vasodilation)` ayiyona into okufanele ukhathazeke ngayo. Eqinisweni, ungase ungaqapheli nokuthi une-`(Vasodilation)` ngoba awukwazi ukuyibona. Kodwa-ke, ungayibona imiphumela yayo. Isibonelo, uma uquleka, kungaba ngenxa ye-`(blood pressure)` ephansi. Uma umfutho wegazi wakho wehla kakhulu futhi uba `(shock)`, kungaba yingozi empilweni.

Izimpawu zokushaqeka zingafaka:

• Izinguquko esimweni sengqondo: ukucasuka, ukungahlaliseki, noma ukudideka, njengokungathi ulahlekile.
• Ukushintsha kombala wezindebe neminwe.
• Ukuzungeza, ukuba nekhanda elikhanyayo, noma ukuquleka.
• Isikhumba siyabanda, sijuluke, noma sibe mhlophe. Njengokungathi ulahlekelwe igazi elincane.
• Ukujuluka ngokweqile.
• Ukuphefumula kuyashesha noma kujule.
• Ukushaya kwenhliziyo okusheshayo nokubuthakathaka.

Uma umuntu equleka futhi usola ukuthi "ushaqekile", kufanele wenze lezi zinto:

• Hlala uzolile, ungesabi. Shayela u-1990 (insizakalo ye-ambulensi ephuthumayo yaseSri Lanka) ngokushesha. Ungalindi kuze kube yilapho izimpawu ziba zimbi kakhulu. Umzuzwana ngamunye uyabalwa.
• Hlola ukuthi indlela yokuphefumula yomuntu ihlanzekile. Ingabe uyaphefumula? Ngisho noma ephefumula, hlola njalo ngemizuzu emihlanu kuze kufike i-ambulensi. Khulula noma yiziphi izingubo noma amabhande angase avaleleke.
• Hlola ukushaya kwenhliziyo. Uma kungekho ukushaya kwenhliziyo, qala ngokushesha ukuvuselela inhliziyo (CPR) bese uqhubeka kuze kufike usizo.
• Uma umuntu engenalo ukulimala okukhulu ekhanda, entanyeni, emilenzeni, noma emhlane,Beka umcamelo noma okuthile ngaphansi kwemilenze yakhe bese umphakamisa cishe unyawo (amasentimitha angu-12). Lokhu kubizwa ngokuthi "indawo yokushaqeka". Ungaphakamisi ikhanda lakhe nganoma yisiphi isizathu.
• Uma kungenzeka futhi kufaneleka, nikeza usizo lokuqala kwezinye izingozi ezibonakalayo.
• Gcina umuntu efudumele. Kungaba ngcono uma engambozwa ngengubo yokulala.
• Ningabaniki lutho lokudla noma lokuphuza.
• Uma umuntu ehlanza noma ephuma amafinyila emlonyeni wakhe, futhi kungekho okusolakala ukuthi kukhona ukulimala ekhanda, entanyeni, noma emhlane, phendula ikhanda lakhe liye ohlangothini olulodwa ukuze uvimbele ukuminyana.

Okokugcina, izinto okufanele uzikhumbule

I-Vasodilation empeleni inqubo yemvelo eyenzeka emizimbeni yethu ekhulisa ukugeleza kwegazi futhi yehlise umfutho wegazi. Isikhathi esiningi, lokhu kuyasiza kithi. Lokhu kungenxa yokuthi kusiza ukuthwala umoya-mpilo nezakhamzimba emzimbeni wonke. Kodwa-ke, kwezinye izimo, i-vasodilation ingaba yingozi. Kungabangela ukwehla okukhulu kwegazi (umfutho wegazi ophansi).

Ngakho-ke, qaphela izimpawu "zokwethuka": izinguquko esimweni sengqondo, isikhumba esibandayo, kanye nokuphefumula okungajulile noma okusheshayo. Uma wena noma othile omaziyo ehlangabezana nanoma yiziphi zalezi zimpawu ezesabekayo, funa usizo lwezokwelapha ngokushesha. Yilokho okungcono kakhulu ongakwenza.

ukuvuvukala kwemithambo yegazi, imithambo yegazi, umfutho wegazi, ukujikeleza kwegazi, i-anaphylaxis, ukushaqeka kwe-septic, usizo lokuqala, ukwehla komfutho wegazi, ukushaqeka
