Namuhla, sizoxoxa ngenqubo ebaluleke kakhulu eyenzeka emzimbeni wakho njengamanje: indlela igazi eligeleza ngayo emithanjeni yakho yegazi, eyaziwa ngokwezokwelapha ngokuthi i-hemodynamics . Nakuba kungase kuzwakale njengegama eliyinkimbinkimbi lesayensi, empeleni lo mqondo ulula kakhulu. Uma usuwuqonda, uzothola isithombe esicacile kakhulu sempilo yenhliziyo yakho nokuthi izimo ezahlukene zenhliziyo zikuthinta kanjani.
Iyini Ngempela I-Hemodynamics?
Kalula nje, i-hemodynamics ibhekisela emandleni kanye nobuchwepheshe obuhilelekile endleleni igazi lakho eligeleza ngayo ohlelweni lwakho lwenhliziyo nemithambo yegazi—ikakhulukazi imithambo yakho yegazi (imithambo yegazi ethwala igazi elinomoya-mpilo elisuka enhliziyweni yakho) kanye nemithambo yakho yegazi (imithambo yegazi ebuyisela igazi elingenawo umoya-mpilo enhliziyweni yakho).
Ngaphansi kwezimo ezijwayelekile nezinempilo, igazi lakho ligeleza kahle nangendlela ehlelekile, njengomfula ozolile, ogeleza kancane kancane. Lokhu kubizwa ngokuthi ukugeleza kwe-laminar . Uma igazi ligeleza ngale ndlela, kuba nokungqubuzana okuncane ezindongeni zemithambo yegazi, futhi igazi eliphakathi nendawo lemithambo yegazi lihamba ngokushesha okukhulu.
Kodwa-ke, ukugeleza kwegazi ngezinye izikhathi kungaba yinto engahlelekile futhi engahlelekile, kufana namanzi azungeza amatshe ezindaweni ezisheshayo. Lokhu kwaziwa ngokuthi ukugeleza okuguquguqukayo . Ngokuvamile uthola ukugeleza okuguquguqukayo emakamelweni aphansi enhliziyo yakho ( ama-ventricle ), ezindaweni lapho imithambo yegazi ihlukana khona, noma lapho umthambo wegazi uncipha noma unwebeka khona ngokuzumayo. Kudinga amandla amaningi ukuze inhliziyo yakho ipompe igazi ngaphansi kwezimo eziguquguqukayo ngoba ukugeleza akusebenzanga kahle.
Cabanga ngenhliziyo yakho njengephampu ephakathi eyinkimbinkimbi kakhulu. Uma ishaya, ihambisa igazi kuwo wonke umzimba wakho. Umthambo wakho omkhulu, i -aorta , kanye nenethiwekhi yayo yemithambo ehlanganisa amagatsha ithwala umoya-mpilo nezakhamzimba ezibalulekile kuzo zonke izicubu zakho. Uma izitho zakho zikhipha umoya-mpilo eziwudingayo, igazi libuyela enhliziyweni yakho ngemithambo yakho. Inhliziyo yakho bese ipompa leli gazi elingenawo umoya-mpilo emaphashini akho ukuze lithole umoya-mpilo omusha, bese umjikelezo uqala kabusha.
Ngezinye izikhathi, izithiyo zingaphazamisa lo mgwaqo oqhubekayo. Isibonelo, i-cholesterol (uhlobo lwamafutha, olwaziwa ngokuthi i-cholesterol ) inganqwabelana ngaphakathi kwemithambo yakho yegazi. Sibiza lawa ma-fatty deposits ngokuthi i-plaque , futhi asebenza "njengeziphazamiso zesivinini" ezivimbela ukugeleza kwegazi. Uma i-plaque deposit iqhuma ngokuzumayo, ingakha i-clot futhi ivimbe ngokuphelele imithambo yegazi.
Ngaphezu kwalokho, ihlule legazi lingavimba umkhumbi wegazi ngokomzimba. Ngokufanayo, uma imisipha yenhliziyo yakho iba buthaka, ngeke ikwazi ukupompa ngamandla anele ukuhlangabezana nesidingo sezicubu zakho somoya-mpilo nezakhamzimba.
Uma kwenzeka noma yikuphi kwalokhu kuphazamiseka, uhlelo lwakho lokujikeleza kwegazi luyahluleka ukusebenza kahle. Lokhu kusho ukuthi amangqamuzana akho, izicubu, kanye nezitho ezibalulekile azikwazi ukuthola igazi elanele—futhi ngenxa yalokho, umoya-mpilo kanye nezakhamzimba—ezidingayo ukuze zisebenze kahle.
Kungani I-Hemodynamics Ibalulekile Kuwe?
Kuleli qophelo, ungase uzibuze, "Kulungile, yileyo ndlela igazi eligeleza ngayo. Kungani lokhu kubalulekile kimi?" Eqinisweni, ukuqonda i-hemodynamics yakho kubaluleke kakhulu ekuphatheni impilo yakho.
Ngokuqaphela izici ezilawula ukugeleza kwegazi lakho, ungaqonda kangcono izifo zenhliziyo nokuthi ukwelashwa kusebenza kanjani. Isibonelo, uma wazi ukuthi umfutho wegazi ophakeme uphoqa inhliziyo yakho ukuthi isebenze kanzima kakhulu ukupompa igazi, kunengqondo ukuthi kungani udokotela wakho engase akunike umuthi wokuphumula nokukhulisa imithambo yegazi yakho. Le ndlela ebanzi inciphisa ukumelana, okuvumela umfutho wegazi wakho wehle.
Udokotela wakho usebenzisa idatha ye-hemodynamic ukuze athole ukuxilongwa okunembile futhi anqume ukuthi uzogula yini.(indlela isimo esizoqhubeka ngayo). Isibonelo, bangahlola ukuthi ivalvu yenhliziyo evuzayo ivumela igazi ukuthi libuyele emuva yini, okulivimbela ukuthi lifike lapho liya khona. Kusisiza futhi ukuthi silandelele ukuthi ukuhlinzwa kwakamuva noma umuthi omusha kuyathuthukisa yini ukujikeleza kwegazi lakho ngempumelelo.
Ingabe i-Hemodynamics Imane Ingenye Igama Elisho Ukucindezeleka Kwegazi?
Akunjalo ngempela. Nakuba umfutho wegazi uyingxenye ebalulekile, empeleni ungomunye wemicinto eminingi udokotela wakho ayibhekayo lapho ehlola i-hemodynamics yakho iyonke. Amanye amandla amaningi ashukumisayo anquma ukuthi igazi lihamba kanjani emzimbeni wakho.
Yiziphi Izinto Ezithonya Ukugeleza Kwegazi Lakho? (Izici Ze-Hemodynamic)
