Yintoni i-vasodilation? Makhe sithethe ngayo ngokulula!

Ngaba wakha wazibuza ukuba kutheni imithambo yegazi emzimbeni wakho ngamanye amaxesha iba mikhulu kwaye ngamanye amaxesha ibe mincinci? Oku kwandiswa kwemithambo yegazi yinto esiyibiza ngokuba yi-'(Vasodilation)' kwisayensi yezonyango. Nangona oku kuyinto eqhelekileyo eyenzekayo emizimbeni yethu ngamaxesha onke, ngamanye amaxesha kunokubangela iingxaki ezinkulu. Ngoko ke, masifunde ukuba yintoni kanye kanye i-'(Vasodilation)' namhlanje, akunjalo?

Yintoni kanye kanye `(iVasodilation)`? Kwenzeka njani oku?

Ngamafutshane, "iVasodilation" kukwanda kwemithambo yegazi emzimbeni wakho. Xa le mithambo yegazi ikhula, igazi elininzi lihamba kuyo. Oku kunciphisa uxinzelelo lwegazi. Le yinto eyenzekayo emzimbeni wakho ngalo lonke ixesha, nokuba awuqondi.

Ngoku, jonga umsebenzi wegazi emizimbeni yethu. Igazi lethu lilo elithwala ioksijini kunye nezondlo emzimbeni, kwaye likwanceda ekulawuleni ubushushu bomzimba.

Ngoko ke le mithambo yegazi ayizizo nje iityhubhu. Inezihlunu ezixineneyo. Le misipha yiyo egqibayo ukuba imithambo yegazi kufuneka ikhule nini kwaye incinci nini. Xa imithambo yegazi ikhula ngolu hlobo, siyibiza ngokuba yi-'(Vasodilation)'. Elinye icala lale nto, xa imithambo yegazi incinci, libizwa ngokuba yi-'(Vasoconstriction)'. Uyaqonda?

Le `(Vasodilation)` yenzeka nini ngokwendalo?

Ezi zinto zisenokuba zenzeke nakuwe, jonga le mizekelo:

• Xa uziva uneentloni, ubuso bakho bujika bube bomvu, akunjalo? Ngelo xesha, ubuso bakho buziva bushushu kancinci, kuba imithambo yegazi emincinci engaphantsi kolusu lwakho, esiyibiza ngokuba yi-"capillaries", iba yi-"vasodilated." Emva koko ukuhamba kwegazi ebusweni bakho kuyakhula. Kufana nomntwana omncinci oneentloni.
• Xa ungena kwi-hot tub: Wakungena nje emanzini ashushu, ii-capillaries emzimbeni wakho ziqala ukwanda. Oku kukunceda ukulawula ukwakheka kobushushu ngequbuliso emzimbeni wakho kwaye kukuncede uhlale ufudumele. Nangona kunjalo, yingakho kungalungi ukuhlala emanzini ashushu ixesha elide. Ukuba wenza njalo, uxinzelelo lwakho lwegazi lunokwehla kakhulu kwaye usenokuphelelwa ngamandla. Ngoko ke lumka!
• Xa uzilolonga: Xa uzilolonga nzima, ubaleka, okanye utsiba, iiseli zomzimba wakho, ingakumbi iiseli zemisipha, zifuna ioksijini kunye nezondlo ngokukhawuleza. Emva koko imithambo yegazi iyavuleka ize ithumele igazi elingakumbi ukuhlangabezana naloo mfuno.
• Xa kukho usulelo emzimbeni: Khawuthelekelele ukuba unenxeba emzimbeni wakho eliqale ukudumba. Xa kukho usulelo olunjalo, umzimba wethu usabela ngokwandisa ukuhamba kwegazi ukuya kwindawo enesifo. Oku kwenza kube lula emzimbeni ukulwa nosulelo nokulungisa umonakalo oluwenzileyo.

Ngaba izinto esizityayo nesiziselayo zingabangela "i-Vasodilation"?

Ewe, kunokwenzeka ngenene. Ezinye zezinto esizityayo nesiziselayo zinokubangela ukuba imithambo yegazi ivuleke kwaye yehlise uxinzelelo lwegazi. Jonga:

• Ukutya okune-nitrate eninzi:Imifuno eluhlaza efana nesipinatshi, ilettuce, iiradishes, kunye nebok choy ziphezulu kwi-nitrates. Imizimba yethu iguqula ii-nitrates zibe yikhemikhali ebizwa ngokuba yi-nitric oxide. I-nitric oxide yindlela entle yokwandisa imithambo yegazi.
• Utywala: Wakuba usele utywala obuncinci, i-"Vasodilation" nayo iyenzeka emzimbeni. Yiyo loo nto abanye abantu behlanza igazi xa besela utywala. Kodwa oku kwenzeka okwexeshana. Emva kwexesha elithile, uxinzelelo lwegazi lubuyela esiqhelweni. Kodwa khumbula, ukuba usela utywala obuninzi, uxinzelelo lwakho lwegazi luya kunyuka. Esi sesona sizathu sokuba oogqirha bacebise ukuba bangaseli kakhulu.

Ngaba kukho amayeza abangela "i-vasodilation"?

Zininzi kakhulu. Amanye amayeza enzelwe ukubangela "i-Vasodilation." Oku kwenzeka njengesiphumo esingesihle samanye amayeza.

• Amayeza oxinzelelo lwegazi: Uninzi lwamayeza oxinzelelo lwegazi oluphezulu lusebenza ngokwandisa imithambo yegazi. Lowo ngumsebenzi ophambili waloo mayeza.
• I-Nitroglycerin: Le ikwayi-vasodilator eyaziwayo. Isetyenziselwa ukunyanga ukuhlaselwa sisifo sentliziyo kunye neentlungu zesifuba, okwaziwa ngokuba yi-angina.
• Amayeza okungasebenzi kakuhle kwe-erectile: Amayeza afana neSildenafil (ekwaziwa ngokuba yiViagra®) asebenza ngokuvaleka kwegazi. La mayeza andisa ukuhamba kwegazi ukuya kwi-penis.

Yintoni omawuyenze ukuba uxinzelelo lwegazi luyehla kakhulu ngenxa ye-`(Vasodilation)`?

Ukuba uxinzelelo lwakho lwegazi luyehla kakhulu ngenxa yokwanda kwemithambo yegazi, okubizwa ngokuba yi-hypotension, kukho iindlela ezahlukeneyo zokuyinyanga. Oku kudla ngokwenzeka esibhedlele.

• Ukuvuselela ulwelo: Oku kuquka ukunika ulwelo, olufana ne-saline, emthanjeni (ii-IV fluids). Oku kunyusa ubungakanani bolwelo emzimbeni kwaye kunceda ekunyuseni uxinzelelo lwegazi.
• Amayeza oxinzelelo lwegazi: Kukho iintlobo ezimbini zamayeza, ``Vasoconstrictors'' kunye ``Vasopressors'', asetyenziselwa ukunyanga uxinzelelo lwegazi oluphantsi. La mayeza asebenza ngokubangela ukuba imithambo yegazi evulekileyo inciphe (vasoconstriction), nto leyo ebuyisela uxinzelelo lwegazi esiqhelweni.

Ngaba `(Vasodilation)` ingaba yingozi?

Ewe, kwezinye iimeko oku kunokuba yingozi. Kuxhomekeke kwisizathu se-"Vasodilation", ukuba yenzeka nini, kunye nobunzima bayo. Kwezinye iimeko ezigqithisileyo, ukwanda kwemithambo yegazi (kunye neempawu ezinxulumene nayo) kunokuba yingozi nakubomi.

Khawuthelekelele oku: Kwiimeko ezisongela ubomi ezinje, `(Vasodilation)` nayo yimbangela:

• Iimpendulo eziqatha ze-allergy:Oku kukwabizwa ngokuba yi-`(Anaphylaxis)`. Oku kuxa inkqubo yomzimba yokuzikhusela isabela kakhulu kwinto ethile (umz. ukutya, amayeza, ukutyiwa zizinambuzane) kangangokuba inokubulala. Xa i-`(Anaphylaxis)` isenzeka, umntu uba `(shock)`, `(blood pressure)` yehla ngendlela eyingozi, kwaye iindlela zomoya ziyavaleka, okwenza kube nzima ukuphefumla. Iyeza `(Epinephrine)` elinikwayo kwimeko engxamisekileyo linamandla `(vasoconstrictor).` Oko kukuthi, liphinda linyuse `(blood pressure)`, lincede ekwenzeni ukuphefumla kube lula, kwaye linciphise impendulo yomzimba.
• Ukothuka kweSeptic: ISepsis yimeko esongela ubomi apho umzimba usabela kabukhali kwisifo kangangokuba inokuba yingozi ebomini. Ukothuka kweSeptic lolona hlobo lubi kakhulu (kwaye lunokuba yingozi) lwesi sifo. Kule meko, uxinzelelo lwegazi luyehla kakhulu ngenxa yokwanda kwemithambo yegazi emzimbeni wonke). Kwimeko enzima kangaka, ulwelo lwe-IV kunye namayeza okonyusa uxinzelelo lwegazi ayimfuneko ukusindisa ubomi bomntu.

Ufanele uye nini kugqirha malunga ne-`(Vasodilation)`?

Ixesha elininzi, i-`(Vasodilation)` ayisiyonto ibalulekileyo yokuyikhathaza. Enyanisweni, usenokungazi nokuba unayo i-`(Vasodilation)` kuba awukwazi ukuyibona. Nangona kunjalo, unokubona iziphumo zayo. Umzekelo, ukuba uyafa isiqaqa, isenokuba ngenxa ye-`(uxinzelelo lwegazi)` ephantsi. Ukuba uxinzelelo lwakho lwegazi luyehla kakhulu kwaye ube `(umothuko)`, lunokuba yingozi ebomini.

Iimpawu zokothuka zingabandakanya:

• Utshintsho kwimeko yengqondo: ukuphazamiseka, ukungazinzi, okanye ukudideka, ngokungathi ulahlekile.
• Ukutshintsha kombala oluhlaza okwesibhakabhaka kwemilebe kunye neminwe.
• Ukuba nesiyezi, ukuba nentloko ekhaphukhaphu, okanye ukuquleka.
• Ulusu luyabanda, lubile, okanye lube mhlophe. Ngokungathi ulahlekelwe ligazi elincinci.
• Ukubila okugqithisileyo.
• Ukuphefumla kuba nzulu okanye ngokukhawuleza.
• Ukubetha kwentliziyo okukhawulezayo nokubuthathaka.

Ukuba umntu uyawa uze ucinge ukuba "uyothuka", kufuneka wenze ezi zinto zilandelayo:

• Hlala uzolile, ungoyiki. Fowunela u-1990 (inkonzo ye-ambulensi engxamisekileyo yaseSri Lanka) ngoko nangoko. Musa ukulinda de iimpawu zibe mandundu. Yonke imizuzwana ibalulekile.
• Qinisekisa ukuba indlela yomoya yomntu icocekile. Ngaba uyaphefumla? Nokuba uyaphefumla, jonga rhoqo emva kwemizuzu emihlanu de kufike i-ambulensi. Khulula nayiphi na impahla okanye amabhanti anokubambeka.
• Jonga ukuba i-pulse ayibonakali na. Ukuba akukho pulse, qalisa ngoko nangoko ukuvuselela i-cardiopulmonary (CPR) uze uqhubeke ude ufumane uncedo.
• Ukuba umntu akanakwenzakala kakhulu entloko, entanyeni, emilenzeni, okanye emqolo,Beka umqamelo okanye into ethile phantsi kwemilenze yakhe uze umphakamise malunga neenyawo (ii-intshi ezili-12). Oku kubizwa ngokuba yi-"shock position". Musa ukuphakamisa intloko yakhe nangasiphi na isizathu.
• Ukuba kunokwenzeka kwaye kufanelekile, nika uncedo lokuqala kwezinye iingozi ezibonakalayo.
• Mgcine efudumele loo mntu. Kungangcono ukuba angagqunywa ngengubo.
• Musa ukubanika into yokutya okanye yokusela.
• Ukuba umntu uyahlanza okanye une-mucus ephuma emlonyeni wakhe, kwaye akukho mathandabuzo okuba kukho ukwenzakala entloko, entanyeni, okanye emqolo, jika intloko yakhe iye ecaleni ukuze angaminxeki.

Okokugqibela, izinto ekufuneka uzikhumbule

I-Vasodilation yinkqubo yendalo eyenzeka emizimbeni yethu eyonyusa ukuhamba kwegazi kwaye yehlise uxinzelelo lwegazi. Uninzi lwexesha, oku kuluncedo kuthi. Oku kungenxa yokuba kunceda ukuthwala ioksijini kunye nezondlo emzimbeni wonke. Nangona kunjalo, kwezinye iimeko, i-vasodilation inokuba yingozi. Inokubangela uxinzelelo olukhulu lwegazi (uxinzelelo lwegazi oluphantsi).

Ngoko ke, khangela iimpawu "zokothuka": utshintsho kwisimo sengqondo, ulusu oluthambileyo, kunye nokuphefumla okuncinci okanye okukhawulezayo. Ukuba wena okanye umntu omaziyo ufumana naziphi na zezi mpawu zoyikekayo, funa uncedo lwezonyango ngokukhawuleza. Yiloo nto ilungileyo onokuyenza.

ukujikeleza kwegazi , imithambo yegazi, uxinzelelo lwegazi, ukujikeleza kwegazi, i-anaphylaxis, ukothuka kwe-septic, uncedo lokuqala, uxinzelelo lwegazi oluphantsi, ukothuka
