Impendulo ye-vagal yindlela yokuphendula ngokuzenzekelayo emzimbeni wethu eyenzeka ngenxa yesiphumo se- vagus . Ifumana igama layo kwinto yokuba ibandakanya ukubandakanya phakathi kwentsholongwane yakho yegazi kunye nemithambo yakho yegazi. Xa i-nerus vagus ivuselelwe ngokukhawuleza, ibeka ikhetho yeziganeko ngaphakathi komzimba. Njengoko uza kubona ngezantsi, olu tshintsho lunokubangela iintlobo ezahlukeneyo zokuvakalelwa kunye neempawu.
I-vagal response ihamba ngamagama amaninzi, kuquka:
- Vasovagal reflex
- Impendulo yeVasovagal
- Ukuhlaselwa kweVasovagal
- I-refag reflex
Vagal Response Adggers
Kukho iintlobo zezinto ezibangela ukuba zisuse iimpendulo zesondo. Njengoko uza kubona, ezinye zezi zinto zibangele ngaphakathi, kanti ezinye zivela kwimeko:
- Ukuxinezeleka ngokomzwelo
- Igazi litsalwe okanye ibona igazi
- Uloyiko
- Ukugula kwesisu
- Ukuba neentshukumo zokuhamba
- Ukushisa
- Ubuhlungu
- Ukuma ixesha elide
- Ukuma ngokukhawuleza
- I ngxaki
Iimpawu zeempendulo zeVagal
Emva kokuba i-reflex vasovagal ikhutshwe, kukho iimpawu ezahlukahlukeneyo zomzimba. Ezi ziquka:
- Umbono ogqityiweyo okanye we-tunnel
- Utywala
- Ukutyhafa
- Ndiziva ndifudumele
- Intloko yokukhanya
- I sizathu
- Ukubetha ezindlebeni
- Isikhumba sizizwa sibanda kwaye sinqabile
- Ukuxela
- Ukuguquka okuluhlaza
Yintoni eqhubekayo kwiQumrhu lakho
Impendulo ye-vagal iquka inkqubo yakho ye-nervous central, inkqubo yakho ye-nervous system, kunye ne-cardiovascular system system. Xa i-reflex ibangelwa kukudala ukuphosa ngokukhawuleza kwegazi lakho kunye nokunciphisa ngokukhawuleza kwintliziyo yakho.
Imithambo yegazi emilenzeni yakho ingaba yanda, eyenza igazi lidibanise emilenzeni yakho, enokunyusa ukunyusa uxinzelelo lwegazi. Zonke ezo zinguqu zinokubangela ukuba igazi elincinci liqhubekele engqondweni yakho kwaye lenze ukuba uzive ngathi unokuphelelwa amandla.
Ekubi kakhulu, i-reflex ingakhokelela ekulahlekelweni okufutshane kwimeko ekhoyo, imeko eyaziwa ngokuthi ( vasovagal syncope) .
Kubalulekile ukwazi ukuba ukufumana iziganeko ezinokubangelwa yimpendulo yangasese akuthethi ukuba kukho into engalunganga kuwe. Kucingelwa ukuba i-reflex iyonke. Yintoni eyahluka kumntu kumntu yinqanaba le-reactivity lokubangela, ngamanye amagama, indlela enokuthi unokufumana ngayo iimpawu ezivela kwi-reflex.
Vasovagal Syncope
Akukho ncoko yempendulo ye-vagal igqibe ngaphandle kokuqwalasela i-vasovagal syncope. I-Syncope yinto yokuphelelwa amandla ngenxa yokunciphisa uxinzelelo lwegazi kunye nokunciphisa okuqhubekayo ekuqhubeni kwegazi kwingqondo. Ngaloo ndlela i-syncope ye-vasovagal yilahleko yokuphazamiseka okubangelwa yi-vagal response.
I-syncope yeVasovagal inokubangela umntu ukuba adlule kwaye ahlele phantsi. Nge syncope, isimo sokungazi kakuhle sihlala nje imizuzu emibini. Njengoko ukuhamba kwegazi kubuyela ebuchosheni, umntu uya kubuyela kwiimeko eziqhelekileyo zokuqonda.
Yintoni ongayenza Ukuba ufumana iziqephu zeVasovagal
Isiqendu se-vasovagal sinokuyikrakra kodwa kaninzi asikho uphawu loxinzelelo lwezempilo. Into engcono ukuyenza kukuba ulale phantsi malunga nemizuzu eyi-10 okanye njalo. Enye inketho kukunciphisa intloko phakathi kwamadolo.
Ukusela kwamanzi kunokuncedisa ngokunjalo. Nantoni na oyenzayo, musa ukuma ngokukhawuleza njengoko uzibeka engozini yokuphelelwa amandla.
Unokukwazi ukukhusela ezo ziqendu ngokufumana ubuthongo obuhle, uzigcine uzilungele kakuhle kwaye ukhuphe ukuma ixesha elide. Ukuba ufumana iimpawu ze-vasovagal xa unentshukumo yokuhamba, njengabantu abathile abanomdla wokugulisa isisu , unokufuna ukuzama ukuzigcina ukhululekile, kunye nentloko yakho phantsi kwaye imilenze yakho iwela xa uhlala kwindlu yangasese ukuze uzame ukugcina yakho uxinzelelo lwegazi luzinzileyo.
Nangona i-vagal response ingasifumana ngumntu onempilweni enempilo, ihlala ilungileyo ukuvumela ugqirha wakho ukuba azi ukuba kwenzeka ntoni kuwe.
Ngokusekelwe kwiimpawu zakho kunye nembali yakho yonyango, ugqirha uya kugqiba isigqibo sokuba ngaba uphando olongezelelweyo lufanelekile.
