Ingabe Uyihlanza Ngempela Inhliziyo?
Okokuqala, kwakukhona ukubhuka komzimba kwangaphakathi- ngokuyisisekelo i-doc yavula isifuba sakho, ifinyelela ngaphakathi, futhi yacindezelwa-kodwa ekugcineni yafika into entsha entsha ebizwa ngokuthi i-massage yangaphandle ye-cardiac noma i-massage ye-cardiac evulekile . Lezi zinsuku zonke izingane zizibiza ngokuthi i- chest compression , okuyigama elingcono kakhulu kusukela inhliziyo igxile kakhulu esifubeni ekutholeni ukusikhipha.
Ngakho-ke, ungase ubuze, uma inhliziyo ingatholi isikhathi sayo se-spa, ngabe kanjani emhlabeni ukucindezela kwesifuba kwenza igazi lihambe?
Imifino Kufanele Yithole Iningi Lesikweletu
Ukuze kube mnandi, yonke imithwalo yegazi isisiza ukuqondisa igazi ukuqondisa phakathi kwesigubu esifubeni ngesikhathi se- CPR , kodwa kunesici esisodwa esiyingqayizivele semithanjeni esisiza ukuhambisa yonke into. Ngaphandle kosizo lwezinyosi, angicabangi ukuthi le nto yeCPR izosebenza konke lokho.
Izitsha zegazi 101
Amapayipi athatha igazi emzimbeni wethu ahlelwe ngokulinganayo kweyodwa yezinhlobo ezintathu: imishanguzo , imithanjeni, nama- capillaries . Ama-Capillaries yiwona omncane kunayo yonke imithwalo yegazi, kangangokuba avumela kuphela amangqamuzana egazi abomvu ngefayela elilodwa. Kunama-capillari amaningi kakhulu kumasentimitha angu-skwele ngalinye kanye nezinye izicubu ezingenakwenzeka ukuzibona ngamehlo. Ngempela, uma ubheka imisipha nezinye izicubu ezithambile, kubonakala sengathi zanyiswe egazini kunokuba zichazwe imithwalo yegazi egijima kuyo.
Ngihlale ngicabanga ngezicubu njengezimponta namapillazi njengamashaneli esiponini esiwusizo ekutheni ziqukethe amanzi. Sizobuyela embonweni wesiponithi ngomzuzu.
Imishanguzo yizona izitsha ezithwala igazi kusukela enhliziyweni kuya ezicukwaneni. Lezi yiziphazamisi eziphezulu zokucindezela ezinezindonga ezinamandla ezinamandla okukhulisa noma ukunciphisa ukuze kusize ukulawula ukugeleza.
Uma sesisha, sisencane futhi sinempilo, lezi zicacile futhi zivulekile. Ngokuhamba kwesikhathi njengoba sikhula, sithola isikhala esithile (esibizwa ngokuthi i- plaque ) esenza ngaphakathi. I-plaque yakha kancane kuwo wonke umuntu, kodwa kubantu abathola ipuleti kakhulu-ikakhulukazi emithanjeni ethwala igazi ensikeni yenhliziyo-bafaka ingozi yokuvimbela ukugeleza kwegazi, okungaholela ekuhlaselweni kwenhliziyo kanye nemivimbo .
Imifino iqoqa igazi ezihlakalweni futhi isithuthele emuva enhliziyweni. Lezi zinsizwa zibhekana nezingcindezi ezincane kakhulu kunezingcingo futhi zinezindonga ezincane. Awakwazi ukukhulisa nokuvimbela. Ukugcina igazi lihamba ngokucindezela okuncane kangaka, noma kunjalo, imivamisa inento eyodwa ebalulekile ukuthi imishanguzo ayi: izivali .
Ama-valves atholakele emithanjeni avumela igazi ukuthi ligeleze ekuqondeni olulodwa. Ungabona ukuthi lokhu kusebenza kanjani uma ubona imivimbo ngemuva kwesandla sakho. Zama lokhu: vumela isandla sakho sidonsa eceleni kwakho imizuzwana engu-10 noma engu-15. Yisuse kancane. Vumela igazi lixazulule. Manje yenza isibhakela bese uthola imithi ngemuva kwesandla sakho. Vula umunwe kusuka kwesinye isandla uphakamise isifuba sakho enhliziyweni yakho. Umvuthwandaba uyaphuma ngaphandle kodwa awupheli. Manje ugijime umunwe wakho ngenye indlela endleleni yakho, uhlale uphansi uze uphakamise umunwe wakho.
Uma uphonsela igazi ngaphandle, umvuthwandaba uyagubha futhi uma nje ugcina umunwe wakho emvinini ukuyeka igazi elisha ukungena phezulu, lizohlala liphansi. Igazi elisezansi ngeke libuye ngenxa yama-valve.
Ungase ukwazi ngisho ukuthola i-valve esandleni sakho; bheka indawo lapho i-vein engekho flat ngenkathi umunwe wakho usendlini.
Igazi ligeleza ngokucindezeleka
Manje njengoba siqonda ukuthi izitsha zegazi zisebenza kanjani, ake sibone ukuthi lokho kuhumusha kanjani ukugeleza kwegazi uma sicindezela. Khumbula, izicubu zomzimba nemisipha zenza njengezipanji. Uma ucindezela isiponji esilisiwe, uketshezi luphuma kuwo.
Endabeni yezicubu zomzimba, ukucindezela kubangela igazi ngaphandle. Igazi elifakwe ngaphandle kwezicubu lingena emithanjeni noma emithanjeni. Igazi eliya emithanjeni alikwazi ukubuyela ngenxa yama-valve. Ngemuva kokucindezelwa okumbalwa, kunengcindezi eyanele yokuqala ukuhambisa igazi emithanjeni bese ubuyela enhliziyweni.
Inhliziyo ifakwe kule nkampani ye-valve yendlela eyodwa. Ngamunye amakamelo enhliziyo ane valve. Uma igazi liphuma ekamelweni lezinhliziyo, akuvunyelwe ukubuyela emuva kuze kube yilapho lihamba yonke indlela emzimbeni nasemuva. Ungase ungayithinti inhliziyo ngokuqondile ngesikhathi sokucindezeleka, kodwa ngokuqinisekile ugoqa amakamelo avuliwe.
Ukuphumelela nokucindezela
Ukugcoba igazi ngaphandle kwezicubu akuyona yindlela kuphela ekhuthazwa ngayo igazi lapho senza ukuchotshozwa kwesifuba. Njengoba kubalulekile ukuphoqa esifubeni, kubalulekile futhi ukuvumela isifuba ukuba siphumelele (ubuyele esimweni sayo sokuqala). Njenga-siponji, lapho ukhulula izicubu ze-squished, ziphuza uketshezi. Ngaphezu kwalokho, njengoba amakamelo enhliziyo ephakathi kwesifuba futhi anezo valve ezihamba kahle kuzo, ziphuza negazi ngesikhathi sokuphumula.
Kunobufakazi obuningi bokuthi isenzo sokususa se-recoil phakathi kokucindezeleka kwesifuba kubaluleke kakhulu phakathi ne-CPR njengoba kuqhutshwa. Omunye wemibono yokuthi kungani i -CPR yezandla kuphela ephumelelayo ihlobene nokuthi akukho muntu oshaya esifubeni nokunciphisa ikhono layo lokuncelisa igazi. Ngaphandle kwalokho, izigameko eziwela ekuboshweni komzimba ngokungazelelwe, ziningi oksijini kwesokunxele egazini ukuze umlomo emlonyeni awudingekile ngempela .
