Eqinisekisa ukuqhubeka intshukumo igazi iimpahla? Phambili kwaye ibangela ithombo legazi

Ngawo umbuzo wale into eqinisekisa yokuba ukuqhubeka intshukumo igazi ezityeni, yinto umdla. Yinto - le into eyenza phezulu umntu ngamnye. Siyazi nje ukuba luyinyani, kodwa abafane bacinge malunga nendlela eya ukuhamba kwegazi ngaphakathi kwethu. Kwaye kwakungayi kuba akufuneki ukwazi. Ngoko ke, kuyimfuneko ukuba umxelele ngale nto inomdla kakhulu malunga nesihloko.

definition

Ndingathanda ukuqala kwikota, leyo kudala ukususela ezenzelwe le nkqubo ejikeleza - ukuhamba kwegazi ngokusebenzisa iimpahla. Hemodynamics - ukuba ilizwi. Kwaye le nkqubo kwenzeka ngenxa umahluko phakathi ekuthiwa uxinzelelo hydrostatic kwiindawo ezahlukeneyo kwinkqubo yethu kwegazi. Yenzeka njani le nto? Ukuze ukubeka ngamazwi alula, igazi iqala nentshukumo yayo ukusuka kwindawo apho kukho uxinzelelo oluphezulu kulowo apho asezantsi. Yonke kusengqiqweni. Le nkqubo iyonke ixhomekeke kwindlela phezulu kwinkcaso igazi njengoko viscosity layo kunye neendonga beempahla zonke yegazi. Amaxesha amaninzi hemodynamics notorious ezaphukileyo, kwaye ngokuqhelekileyo oku ngenxa yokulimala, ukutsha kunye emzimbeni. Izinga Wazimisela okanye ukuphazamiseka umthamo wegazi abapasa ngomzuzu.

Ukuze ufumane inkcazelo engakumbi malunga ejikeleza

Ngoko ke, ngoku kufuneka ukuthetha ngakumbi malunga nokuba yintoni siqinisekisa ngokuqhubeka intshukumo igazi ngokusebenzisa iimpahla. Le nto ihamba phezu eqinileyo kunye wesekethe nezengekho miphungeni. Bona aziwa kakhulu kuthi, njengoko enkulu isangqa encinane nokuhamba kwegazi. Kodwa ukuze baqalise ukuqonda Okukodwa zabo, kubalulekile ukuqonda indlela "indlela" engundoqo womntu, injini yakhe. Ezizezi - intliziyo.

Oku - i-organ ibalulekileyo, nto leyo evumela ukuhamba kwegazi ngokusebenzisa iimpahla. Ekuqhubekekeni yokumpompoza kwegazi yabangela izishunqulelo rhoqo kwentliziyo. Ekubeni ke hemodynamics igunya lolawulo. Intliziyo yomntu 4-gumbi. Kwicala lasekhohlo igazi esimbaxa, kunye nelungelo, ngokulandelelanayo, lwemithambo. Babengayi tangle entliziyweni yomntu, ngenxa yokuba ezahlulwa zokwahlula. Yintoni enye ukufuna ukwazi? Isibakala sokuba igazi esimbaxa iqulethe ioksijini, kwaye avela entliziyweni. Lwemithambo koko lusiya kuye. Kwaye eli gazi iqulethe carbon dioxide.

imisebenzi

Ukuxelela leyo eqinisekisa ukuqhubeka intshukumo igazi ezityeni, kufuneka kwakhona kuthiwa malunga nemisebenzi hemodynamic. Esebenzisa isangqa encinane ifunyenwe ukuqinisekisa inkqubo eqhelekileyo yokuchaza igesi esivulekayo emiphungeni. Ekubeni ubengena negazi lwemithambo, obubonelela carbon dioxide. Apho ke mpilo. Kwaye, ukutshintsha ulwalathiso, ibuyisela entliziyweni. Kodwa kanye xa umfutho. Unombono le nkqubo, kunokwenzeka ukuba uphendule lo mbuzo ubalulekileyo. Kwaye kuya kuba lula kangangoko kunokwenzeka. Ukuphefumla - lo nto yenza intshukumo igazi ngokusebenzisa iimpahla. Ekuqhubekekeni yokumpompoza kwegazi ebangelwa yinto yokuba siye rhoqo aphefumle. Sonke siyazi ukuba xa uyeka ukuphefumla, ukubetha kwentliziyo ophilisayo, yaye ke, ukuba ngaba ukufunxa emoyeni, uza kufa. Igazi uyayeka flow emiphungeni, ngenxa yokuba umzimba ikhutshwa akukho elide mpilo. Ngako oko, akukho mfuneko yokuba anike icarbon dioxide. Kwaye intliziyo ngegazi wasilela ukuzalisekisa umsebenzi wayo ophambili.

imikhumbi

On kubo kuya kufuneka uxelele. Phambili kwaye ibangela ithombo legazi - oku sisihloko kakhulu multi-amaninzi. Iimpahla lukwa yinxalenye yalo. Ngoko ke, kukho ukothuka ukufunxa, resistive, capacitive, nokutshintshiselana. Yintoni abamele? Eyokuqala kwezi - a umthambo enkulu. Xa iimpahla ukunceda usebenza aorta. Zinelungelo udonga ezizodwa bhetyebhetye - kwaye umbulelo kule luqinisekisa hemodynamics okuqhubekayo.

Resistive ukunika uxinzelelo oluphezulu kwiinqanawa ezinkulu, kwakunye nenkqubo kwegazi elilawulwa kwi emithanjeni, nto leyo, ngokuzenzekelayo, zibizwa ngokuba exchange. Luphawulwa ngeendonga ezibhityileyo. Nika inkqubo igesi exchange lonke olujikeleza. Makubulelwe ke emithanjeni omzimba asuka zonke izinto inkunkuma.

Kwaye, kakade, capacitive imithambo yegazi. Ukuhanjiswa igazi iimpahla ayikwazi bacinge ngaphandle kwazo. Igama baza ngenxa yokuba kuzo umthamo kakhulu igazi yonke into endodeni. Ezizezi - 75 ekhulwini.

isantya ojikelezayo

Indlela ngokukhawuleza lo lwelo ehamba iimpahla zethu, kubalulekile ukuba uyazi, ingakumbi ukufunda umbuzo ukuqinisekisa indlela ukuqhubeka intshukumo igazi ngokusebenzisa iimpahla. Ngoko ke, Velocity aortic ilingana malunga 500 mililitha ngomzuzu. In kwemithambo - 0.5 ml ixesha elifanayo. Indlela ngesantya ibalwa, kulula ukuqonda - izazinzulu ndafumana elide algorithm of yokususwa iyonke. Noko ke, oku akuthethi kuthi.

Ukungena nokuphuma igazi emithanjeni nalo kakhulu fast - 200 mililitha ngomzuzu. Hi ndlela leyi, intshukumo yenziwa apha akukho ngenxa uxinzelelo. Kungenxa ngemithambo iphantsi ngokwaneleyo. lihamba igazi lwemithambo ngenxa umthwalo emagxeni emithanjeni yi amandla kwezihlunu kwezihlunu.

ulwaphulo-mthetho

Ngelishwa, isifo ezinxulumene kunye nokuhamba kwegazi, likufikela abantu abaninzi. Kwaye basoloko imbangela yokufa yokuqala. Stroke, isifo sentliziyo, lwegazi - zonke ezi amagama zaziwa kakuhle kuthi. Kwaye oxhulumene kunye nokuhamba kwegazi. Ngelize, abaninzi banikele ingqalelo kwimpilo yazo. Ngapha koko, uthintelo ngenene elula kakhulu kwaye ayifuni iindleko ezinkulu zemali. Nangona abanye kuba nzima. Ngenxa yokuba kufuneka ukuba uyenze ukuze ayeke ukutshaya. Akukho nto kutheni namhlanje abantu abaninzi kangaka bathwaxwa isifo sentliziyo - umntu nje sijonge inani iintshayi.

Kufuneka kwakhona amodareyithe izixa na utywala obuselwe. Kakade ke, kungcono wenze ngaphandle kwayo. Kwakhona umsebenzi Physical kuza lokuposa. Akukho mfuneko ukuya yonke imihla ukuya ejimini kwaye nikuchithele iiyure ezintathu zoqeqesho - nje imizuzu eli-15-20 ngosuku.

Kakade ke, kufuneka iliso ukutya kwabo. Akukho mfuneko Kwathi ukufumana ukutya inxaxheba uyadinga kakhulu, okanye ngenxa yaso lamiswa umonakalo cholesterol iindonga imithambo yegazi, leyo linciphise le mithambo kwaye ngenxa yoko - ukuphazamiseka kwegazi. Kulungile ukuba endaweni ukutya okungekho mpilweni iziqhamo, imifuno, citrus iziqhamo, iimveliso zobisi, amanzi bezimbiwa. Kodwa oku kuya kuba ngumgwebi elungileyo.
