Iqinisekisa phambili ukuhamba kwegazi ngokusebenzisa izitsha? Ukuqhubeka futhi kubangela ukugeleza kwegazi

Umbuzo ngokuphathelene yokuthi kuqinisekisa ngokuqhubeka ukuhamba kwegazi ngokusebenzisa izitsha, kuyinto ehluke ezithakazelisayo. Kuyinto - ketshezi ukuthi yenza umuntu ngamunye. Esikwaziyo nje ukuthi kuyiqiniso, kodwa kuyaqabukela ucabange indlela uya ukuhamba kwegazi kithi. Futhi ngeke kube engadingekile ukwazi. Ngakho, kubalulekile ukutshela mayelana izinto ezithandekayo mayelana nesihloko.

Ngithanda ukuqala ethemini, okuyinto eye eside kusukela esiqokiwe le nqubo njengoba kunyatheliswa - ukuhamba kwegazi ngokusebenzisa izitsha. Hemodynamics - yilokho izwi. Futhi le nqubo kwenzeka ngenxa umehluko phakathi okuthiwa ingcindezi hydrostatic ezingxenyeni ezahlukene isimiso sethu sokuhamba kwegazi. Kwenzeka kanjani lokhu? Ukukubeka ngamazwi alula singathi, igazi iqala ukuhamba kwayo kusukela endaweni lapho kunengcindezi okusezingeni eliphezulu kulowo lapho ephansi. Konke okunengqondo. Le nqubo yonke incike okusezingeni eliphezulu indlela ukumelana ukugeleza kwegazi njengoba viscosity yayo futhi izindonga zonke imithambo yegazi. Ngokuvamile hemodynamics eziyihlazo siphukile, futhi lokhu ngokuvamile ngenxa yokulimala, ukusha kanye hypothermia. Ezimisele izinga noma ukuphazamiseka umthamo wegazi odlulayo ngomzuzu.

Ukuze uthole ukwaziswa okwengeziwe mayelana kwegazi

Ngakho, manje kufanele kube ukukhuluma kabanzi ngalokho kuqinisekisa ngokuqhubeka ukuhamba kwegazi ngokusebenzisa izitsha. Le nto ehamba phezu okuqinile kanye wesifunda yamaphaphu. Basuke ngaphezulu sekusaziwa yithi, njengoba esikhulu indilinga lencane kwegazi. Kodwa ukuze siqale ukuqondisisa ngokucacile zabo, kubalulekile ukuqonda ukuthi "indlela" main yomuntu, injini yakhe. Okungukuthi - inhliziyo.

Lena - isitho ezibaluleke kakhulu, okuyinto evumela ukuhamba kwegazi ngokusebenzisa izitsha. Le nqubekela phambili legazi ukugeleza okubangelwa Kufinyeta njalo inhliziyo. Njengoba igunya hemodynamics zokulawula. Inhliziyo yomuntu 4-chamber. Ohlangothini lwesobunxele kuyigazi ophakeme, futhi ilungelo, ngokulandelana, emithambo yegazi. Zazingaphenduki tangle enhliziyweni yomuntu, ngoba ahlukaniswa ngodonga. Yini enye engingabuye ngiyenze ukwazi? Iqiniso ukuthi igazi lwemithambo moya une-oksijini, futhi livela inhliziyo. Emithambo yegazi Kunalokho amabombo kuye. Futhi nanti igazi iqukethe-carbon dioxide.

imisebenzi

Ukutshela ukuthi iqinisekisa ngokuqhubeka ukuhamba kwegazi ngokusebenzisa izitsha, kufanele futhi ishiwo imisebenzi hemodynamic. Through the circle encane etholakala ukuqinisekisa ngenqubo evamile negesi lokushintshisana okwenzeka emaphashini. Kusukela lapho engena igazi emithambo yegazi, enezela-carbon dioxide. Lapho, nomoya-mpilo. Futhi, ukushintsha isiqondiso, sibuyisela enhliziyweni. Kodwa nje lapho eseneminyaka ekhipha igazi enhliziyweni. Ukucabanga ngale nqubo, kungenzeka ukuphendula umbuzo obaluleke kunayo. Futhi kuyoba kulula ngangokunokwenzeka. Ukuphefumula - yilokhu kwenza ukuhamba kwegazi ngokusebenzisa izitsha. Le nqubekela phambili legazi ukugeleza kubangelwa yokuthi sihlale ukuphefumula. Sonke siyazi ukuthi uma uyeka yokuphefumula, yokushaya kwenhliziyo ophilisayo, bese, uma yokuthi ayikwazi ukudonsa emoyeni, iza ukufa. Igazi iyeke flow kuya emaphashini, ngoba umzimba ayisekho enikeziwe nomoya-mpilo. Ngakho, asikho isidingo ukuphakela-carbon dioxide. Futhi inhliziyo ngegazi ahluleke ukufeza umsebenzi wayo ophambili nosemqoka.

imikhumbi

On kubo uzodinga futhi ukutshela. Ukuqhubeka futhi kubangela ukugeleza kwegazi - lena isihloko kakhulu yehlukene kaningi okubalwa. Imikhumbi ziyingxenye ebalulekile yalo. Ngakho, kukhona ukushaqeka iyavuleka, resistive, capacitive, futhi exchange. Yini abakubonisayo? Eyokuqala yalezi - a Umthambo ezinkulu. Ngu izitsha cushioning kusebenza le-aorta. Sinenkosi udonga olukhethekile nezimo - futhi sibonga le mfanelo kuqinisekisa hemodynamics okuqhubekayo.

Resistive ukunikeza umfutho ophakeme ezitsheni ezinkulu, kanye elawulwa kwegazi inqubo e-capillary, ngenhlanhla, abizwa ngokuthi exchange. Libhekene izindonga mncane. Nikeza inqubo negesi lokushintshisana kulo lonke uhlelo semithambo. Futhi sibonga yomzimba zihlobene zonke izinto udoti.

Futhi-ke, capacitive imithambo yegazi. Ukuhamba kwegazi ngokusebenzisa izitsha ayikwazi wacabanga ngaphandle kwabo. Igama sebewelele ngenxa yokuthi okukukho ivolumu obuqand lonke igazi okukulo indoda. Okungukuthi - amaphesenti angu-75.

isivinini ukuhamba

ngokushesha kanjani lolu ketshezi eshayela phakathi kwezinye ezitsheni zethu, kubalulekile ukwazi, ikakhulukazi ukutadisha umbuzo kanjani ukuqinisekisa ukuqhubeka ukuhamba kwegazi ngokusebenzisa izitsha. Ngakho, velocity yomthambo i-aorta ilingana mayelana 500 namamililitha ngomzuzwana. Ngo imithambo - 0.5 ml i-ngesikhathi esifanayo. Indlela ijubane ibalwa, okulula ukuyiqonda - Sekuyisikhathi eside ososayensi etholakala algorithm ka imvume Imininingwane. Nokho, lokho akusho ngempela ukutshela.

Notshwala igazi lihambe ngemithambo futhi ngempela fast - 200 namamililitha ngomzuzwana. By the way, ukunyakaza Kwenziwa lapha akukhona ngenxa ingcindezi. Kungenxa ngemithambo uphansi ngokwanele. Emithambo yegazi igazi uhamba ngenxa bafakela izindonga isitsha nge amandla kwemisipha izicubu.

sokwephulwa kwe

Ngeshwa, lesi sifo elihlobene ne kwegazi, kuyomfica abantu abaningi. Futhi ngokuvamile imbangela yokufa kwabo ekuqaleni. Stroke, isifo senhliziyo, umfutho wegazi ophakeme - zonke lezi amagama eyaziwayo kithi. Futhi ukuthi yizinto ezihlobene kwegazi. Ngeze, abaningi bamshaya indiva empilweni yabo. Phela, zokuvimbela empeleni ngokwedlulele elula futhi ayidingi izindleko ezinkulu zezimali. Nakuba abanye bengase kuba nzima. Ngenxa udinga ukwenza ukuyeka ukubhema. Shono ukuthi kungani namuhla abantu abaningi kakhulu abaphethwe isifo senhliziyo - ukuba umuntu amane nje sibheke inani ababhemayo.

Kufanele ungamele amanani utshwala idliwe. Yiqiniso, kungcono ukwenza ngaphandle kwalo. Ukuvivinya umzimba uyophinde singaba usizo kabi. Angisiboni isidingo sokuya nsuku zonke ukuze ejimini futhi bachitha amahora amathathu ku ukuqeqeshwa - imizuzu 15-20 nje ngosuku.

Futhi-ke, kudingeka ukuqapha ukudla kwabo. Asikho isidingo sidlule ukuthola ukudla balwe futhi okunamafutha kakhulu, noma ngenxa kwakheka cholesterol zingcwecwe ezindongeni imithambo yegazi, okuyinto unciphise mafutha anciphisa isikhala esingaphakathi kanti ngenxa yalokho - iziyaluyalu kwegazi. Kungcono ukuba esikhundleni ukudla okungenampilo nge izithelo, imifino, izithelo zohlobo lukalamula, imikhiqizo yobisi, lamanzi esiphethu. Kepha kusukela kulolu kuyoba yijaji ezinhle.
