Ngaba wakha waba namava angaqhelekanga, anamehlo aluhlaza, abangela isiyezi? Mhlawumbi wakha waba namava anjalo ngelixa umi, umi ngequbuliso, okanye usendaweni enabantu abaninzi. Wena nosapho lwakho kumele ukuba benisoyika kakhulu kuba beningakwazi ukuqonda ukuba yintoni ebangela olu hlobo lokuquleka? Namhlanje, siza kuthetha ngovavanyo olukhethekileyo olusetyenziswa ngoogqirha ukufumanisa unobangela ochanekileyo woku. Oku kubizwa ngokuba luVavanyo lweHemodynamic.
Yintoni uvavanyo lweHemodynamic?
Ngamafutshane, uvavanyo lwe-hemodynamic luvavanyo olujonga indlela igazi lakho elihamba ngayo emzimbeni wakho, indlela intliziyo yakho esebenza ngayo, kunye nendlela intliziyo yakho esebenza ngayo. Oku ngamanye amaxesha kubizwa ngokuba 'luvavanyo lokuthambekela kwe-hemodynamic'. Oku kusebenzisa ikhamera ekhethekileyo kunye nenani elincinci kakhulu lezinto ezinemisebe ukuze kufumaneke umfanekiso ocacileyo womsebenzi wentliziyo yakho kunye nemithambo yegazi. Le ndlela siyibiza ngokuba yi-'(nuclear imaging)'.
Kutheni kwenziwa olu vavanyo?
Ukuba usoloko uphelelwa ngamandla, oogqirha baza kusebenzisa ulwazi oluvela kolu vavanyo ukuzama ukufumana unobangela. Ngokwezonyango sibiza ukuphelelwa ngamandla ngokuthi "i-syncope." Iziphumo zolu vavanyo ziza kumisela unyango olungcono kuwe.
Kukho izizathu ezininzi eziqhelekileyo zokuba umntu angakwazi ukuziva ediniwe:
- Ukwehla kwexeshana kokuhamba kwegazi ukuya engqondweni.
- Ukwehla ngequbuliso koxinzelelo lwegazi okanye isantya sentliziyo.
- Utshintsho kubungakanani begazi emzimbeni okanye indlela igazi elisasazwa ngayo.
Amaxesha amaninzi, abantu abaphelelwa ngamandla banokuba nesifo esinxulumene nentliziyo, inkqubo yemithambo-luvo, okanye imithambo yegazi engqondweni yabo. Ngoko ke olu vavanyo lunokunceda ekuchongeni ukuba yintoni kanye kanye loo meko.
Ulungiselela njani ngaphambi kovavanyo?
Ukuze wenze kakuhle kolu vavanyo, kufuneka ulungiselele kancinci. Lumka kancinci ngezi zinto.
| Ingcebiso | Inkcazo |
|---|---|
| Ukukhulelwa | Olu vavanyo alunakwenziwa ukuba ukhulelwe okanye uncancisa, ngoko ke ungacelwa ukuba wenze uvavanyo lokukhulelwa ukuze ukhuseleke. |
| Ukutya neziselo | Musa ukutya okanye ukusela nantoni na kangangeeyure ezine ngaphambi kovavanyo. Musa ukutya nantoni na, efana netshungama okanye itofi. Ukuba kufuneka uthathe amayeza, thatha kuphela ngamanzi athontsi. |
| I-Caffeine | Musa ukusela nantoni na ene-caffeine (iti, ikofu, i-cola) ngomhla wovavanyo. Ziphephe iimveliso ezibhalwe “ezingenayo i-caffeine” okanye “ezingenayo i-caffeine” kuba zisenokuba zisenazo ii-caffeine ezincinci. |
| Ukuba unesifo seswekile | Ukuba unesifo seswekile, cela idinga malunga nentsimbi ye-12:30 emva kwemini. Ngale ndlela unokufumana isidlo sakusasa esilula ngaphambi kwentsimbi ye-8:30 kusasa. Thetha nogqirha wakho ngale nto. |
| Amanye amayeza | Musa ukuthatha amayeza okukhupha isisu okanye amayeza okuhambisa isisu ngaphambi kovavanyo. Sela onke amanye amayeza njengesiqhelo. Buza ugqirha wakho ukuba kukho na amayeza owasebenzisayo ane-caffeine na nokuba kufuneka uwathathe na ngomhla wovavanyo. Musa ukuyeka ukuthatha nawaphi na amayeza ngaphandle kwengcebiso kagqirha wakho. |
Yintoni onokuyilindela ngomhla wovavanyo?
- Impahla: Nxiba impahla nezihlangu ezikhululekileyo. Kuya kufuneka unxibe ilokhwe yesibhedlele egquma isinqe ukususela esinqeni ukuya phezulu ngexesha lovavanyo. Ngoko ke, musa ukunxiba ubucwebe (kuquka nemisesane yomtshato). Musa ukuzisa izinto ezixabisekileyo.
- Izinto onokuzizisa: Zisa iingxelo zakho zamva nje zovavanyo lwezonyango, ezinye iirekhodi zonyango ezinxulumene nemeko yakho, uluhlu lwamayeza onke kunye nezongezo ozithathayo (kunye nobungakanani), kunye noluhlu lwazo naziphi na izinto ezibangela ukuba umzimba wakho ungabi naso isifo.
Uvavanyo luthatha ixesha elingakanani?
Uvavanyo lonke luthatha malunga neeyure ezintathu. Ngoko ke lindela ukuba sesibhedlele malunga neeyure ezintathu. Kuya kufuneka uvuke ngexesha lovavanyo. Abasebenzi baya kukwenza uzive ukhululekile kangangoko. Imifanekiso ecacileyo iya kufumaneka ukuba uhlala ungashukumi kwaye ungashukumi kangangoko.
Kwenzeka ntoni ngexesha lovavanyo?
Olu vavanyo ludibaniso lweendawo ezahlukeneyo, nganye kuzo iqokelela ulwazi olubalulekileyo malunga nentliziyo yakho kunye nokujikeleza kwegazi.
| Indlela yovavanyo | Kwenzekani? |
|---|---|
| Ukubeka iliso kwi-ECG | Izitikha ezininzi ezincinci nezinamathelayo ezibizwa ngokuba yi-"electrodes" zifakwa esifubeni sakho. Ezi zithumela umsebenzi wombane wentliziyo yakho kumatshini we-"EKG/ECG". Oku kunokujonga izinga lentliziyo yakho kunye nepateni kulo lonke uvavanyo. |
| Uvavanyo loxinzelelo lwegazi | Uxinzelelo lwakho lwegazi lulinganiswa kwiindawo ezahlukeneyo ngexesha lovavanyo kusetyenziswa i-blood pressure cuff enamathele engalweni yakho. |
| Iskeni se-Echocardiogram (Echo) | Ngaphambi kokuba uvavanyo luqale, emva kokuba uphumle imizuzu engama-20, uza kwenziwa i-echocardiogram (i-heart scan). Oku kuthatha imifanekiso eneenkcukacha zentliziyo yakho kwaye kulinganisa ukuba ingakanani igazi eliphampa intliziyo yakho ngexesha (i-cardiac output). Olu vavanyo luthathwa ngexesha lovavanyo kwaye luthelekiswa novavanyo lokuqala. |
| Umzobo Wezonyango Zenyukliya | Le yeyona nxalenye ibalulekileyo. Inani elincinci kakhulu lezinto ezine-radioactive ezibizwa ngokuba yi-"radioactive isotope" okanye "tracer" lifakwa kwi-cannula (IV) ebekwe emthanjeni wakho. Emva koko, ikhamera ekhethekileyo ebizwa ngokuba yi-"gamma camera" ithatha imifanekiso yesifuba sakho. Le khamera inokubona imitha ekhutshwa yi-tracer. Le mifanekiso inokukuxelela okuninzi malunga nendlela intliziyo yakho esebenza ngayo, indlela igazi lakho elihamba ngayo ngesantya, kunye nokuba intliziyo yakho ikhupha igazi elingakanani. |
Uza kuziva njani ngexesha lovavanyo?
Ixesha elininzi, akubonakali kubuhlungu kangako. Nangona kunjalo, abanye abantu banokuba nesiyezi , isicaphucaphu, okanye ukubetha kwentliziyo ngokukhawuleza . Oku kuqhelekile.
Eyona nto ibalulekileyo kukuxelela abasebenzi ngoko nangoko ngayo nayiphi na into oyivayo ngexesha lovavanyo, nokuba ayikuphathi kakuhle. Ugqirha uza kusebenzisa zombini iimpawu zakho kunye nolwazi oluvela kuvavanyo ukuze afikelele kwisigqibo malunga nemeko yakho.
Njengoko izinto ezisebenzisa i-radioactive zidlula kwi-cannula, ungaziva umkhuhlane uhla engalweni yakho. Ungaziva nencasa yesinyithi emlonyeni wakho okanye ivumba elingaqhelekanga empumlweni yakho. Ezi mpawu ziya kuphela emva kwexesha elithile.
Kwenzeka ntoni emva kovavanyo?
Emva kokuba uvavanyo luphelile,
- Kuya kufuneka uhlale esibhedlele ude uphele ngokupheleleyo intlungu obuyiva ngexesha lovavanyo.
- Enye ye-tracer esetyenzisiweyo kuvavanyo iya kukhutshwa kumchamo wakho. Okuseleyo kuya kunyibilika ngokwemvelo emzimbeni wakho. Ukuba uyafuna, ungayikhawulezisa le nkqubo ngokusela amanzi ongezelelweyo.
- Uninzi lwabantu luya ngqo emakhaya emva kovavanyo, kodwa ukuba ufumana iimpawu ezinzima (ezifana nokuquleka) ngexesha lovavanyo, licebo elihle ukuba kubekho umntu ohamba nawe.
Ngaba kukho naziphi na iingozi ngolu vavanyo?
Olu luvavanyo olukhuselekileyo kakhulu. Iingozi ezincinci ezinokubakho zezi:
- Usenokuba nokudumba, ukuba bomvu, okanye ukudumba apho kufakwe khona i-cannula. Oku kuqhelekile.
- Izinto ezisebenzisa i-radioactive aziyodayi, ngoko ke azibangeli ii-allergy.
Ubungakanani bemitha esetyenzisiweyo kolu vavanyo buncinci kakhulu. Enyanisweni, bulingana nobungakanani bemitha obunokubonakaliswa kuyo ngexesha le-X-ray yesifuba. Ngoko ke akukho sizathu sokukhathazeka ngayo.
Ingxelo yovavanyo ithini?
Ingxelo efunyanwa ngugqirha wakho iya kukuxelela ukuba iziphumo zakho ziqhelekile okanye aziqhelekanga. Ukuba aziqhelekanga, iya kuchaza nesizathu. Umzekelo:
- Ngaba kukho isigqi sentliziyo esingaqhelekanga?
- Ngaba kukho utshintsho kuxinzelelo lwegazi?
- Ungafumanisa ukuba unengxaki efana nesifo semithambo yegazi emithanjeni yegazi, apho ikhoyo, kwaye iyingozi kangakanani.
- Ingaba kukho ukuncipha kokuhamba kwegazi entliziyweni (ischemia)?
- Ingaba kukho umonakalo kwizicwili zentliziyo (infarction) ngenxa yokulahleka kwegazi kunye neoksijini?
Kudla ngokuthatha iintsuku ezili-10 ukuya kwezili-14 ukufumana le ngxelo. Ngokusekelwe kwezi ziphumo, ugqirha wakho uza kukwenza isicwangciso sonyango. Kusenokufuneka uqalise amayeza amatsha okanye uthunyelwe kwezinye iingcali.
Umyalezo Wokuya Ekhaya
- Ukuba uhlala unesizungu, olu luvavanyo olubaluleke kakhulu lokufumana unobangela ochanekileyo. Ngoko ke musa ukoyika oku.
- Landela imiyalelo kagqirha ngononophelo ngaphambi kovavanyo, ingakumbi malunga nokutya, izinto eziselwayo kunye namayeza.
- Xelela abasebenzi ngokukhawuleza ukuba uziva ungonwabanga (njengokudinwa okanye isicaphucaphu) ngexesha lovavanyo. Oku kubalulekile nakwisifo.
- Ubungakanani bemitha kule nto buphantsi kakhulu, ngoko ke musa ukuyoyika ngokungeyomfuneko.
- Nje ukuba ingxelo ifike, thetha nogqirha wakho ngayo kunye nonyango oluzayo, kwaye ubuze nayiphi na imibuzo onokuba nayo.
