Yintoni na uxinzelelo lwegazi?

Kuxhomekeka lizwe yengcinezelo nasezimpahleni, uxinzelelo igazi zohlulwa ngokwendidi ezintathu: emithanjeni, lwemithambo kunye capillary. Ngenxa uxinzelelo lwegazi lwenziwa promotion ngokusebenzisa iimpahla kwegazi emzimbeni. Ngenxa yoko, ukugcina iinkqubo homeostasis kunye metabolic kuyo. uxinzelelo lwegazi lwemithambo kuxhomekeke amandla izishunqulelo intliziyo, kwakunye umlinganiselo yegazi betekisi ngexesha systole. ukubaluleka ke viscosity na inqanaba uxinzelelo lwegazi esifubeni kunye nesisu, kwakunye mali igazi atyhutyhela emzimbeni.

Ngexesha nokuncipha le ventricle lasekhohlo yengcinezelo yodidi oluphezulu lwegazi intliziyo ufikelela ixabiso elikhulu. Ngeli xesha intliziyo iimpompo malunga 70 cm3 yegazi. Kakade ke, oku kakhulu umthamo omkhulu igazi engenako nangoko kudlula imithambo yegazi ecikizekileyo emithanjeni, ngoko ke udonga ukuzolula aortic, ngeli xesha, uxinzelelo kuyo kwandisa. igazi Normal uxinzelelo (iSystolic) isusela ukusuka 100 ukuya-140 mm HG. column.

uxinzelelo ukuzala ukhandwa ngokunciphisa eludongeni aorta kunye yegazi enkulu. Ngoko ke, igazi zityhalelwa kungena emithanjeni igazi. Kule uxinzelelo lwegazi liyancipha ngcembe yaye nama-70-80 mm HG. column. Kufuneka ke ukuba uxinzelelo lwegazi nasezimpahleni ixhomekeke umgama wabo ngokunxulumene intliziyo, ziqhubeka zivela entliziyweni, incinci ngabakufundileyo uxinzelelo lwegazi. Ukuqinisekisa inqanaba uxinzelelo lwegazi sfingomanometr ukusetyenziswa zonyango.

Oyena nobangela lwegazi (uxinzelelo lwegazi) , iingcali abaninzi bakholelwa ngokweemvakalelo kakhulu, breakdowns luvo, ukudandatheka, kunye nezinye ntshikilelo yengqondo-iimvakalelo. It indiza e luvo zihamba ukunyuka okuthe chu kakhulu kuxinzelelo anterialnym. Izigulane unesifo lwegazi, ukunyuka koxinzelelo lwegazi ngokukhawuleza kwaye sihlala elide, noxinezeleko encinane ngokwasengqondweni-iimvakalelo, xa kuthelekiswa nabantu besempilweni. Ngokufanelekileyo, ukunyuka ngokwenkqubo uxinzelelo lwegazi, umzimba wethu saphule kusetyenziswa, malilungiselelwe umthwalo data, uxinzelelo oluphezulu lwegazi busisigxina kwinqanaba elithile. Lo mbuzo ubangelwa - kufuneka ibe yintoni igazi yesiqhelo uxinzelelo. UNorma ikakhulu ixhomekeke ngeempawu ngamnye komzimba yomntu, ubudala, indlela yokuphila, imisebenzi yomzimba, njl Umzekelo, kuxinzelelo lokufikisa kufuneka 100/70, nokuba abantwana abaneminyaka 60 ngonyaka, oko - 150/90 mm HG. Art.

Into ebalulekileyo kuphuhliso hypertension izifo kwezintso, ukuba bathathe inxaxheba ekumiseleni uxinzelelo lwegazi (ukuphehla ezithile ezimbaxa, impilo esebenzayo). Xa iphazamisekile indlela yokwabiwa isifo sezintso kwazona NaCl, yaye yaziwa ukuba bandiqumbise uxinzelelo lwegazi. Okona kubi kakhulu, xa lwegazi kuba ezingapheliyo. Eli xesha luphawulwa ezinzileyo nehigh blood (lwegazi), emzimbeni wakhe wayethimb imithwalo ezikhoyo, idala uluvo ubuxoki-ntle, oko kukuthi, isigulana phantse akafuni uzive iintlungu, yaye ngenxa yoko, akusekho ukuphathwa.

Ukwazi indlela kwesi sifo uphuhliso kuyo ungalawuleka. Ukuze wenze oku, kufuneka athobele zonke iingcebiso kagqirha, ukuba aqhube ulawulo nangocwangco ukuphumla kunye nomsebenzi, ukunciphisa amandla pisihoemotsionalnogo uxinezeleko emzimbeni. Xa uzingela amagqirha lwegazi amisele iziyobisi kunye okulalisa. amavila unesifo ukuvimbela kufuneka ibe ukuncipha. Lwegazi ke zingqamene ngokugqibeleleyo ne utyebile. Ukutyeba libhekisela kophulwa lweenkqubo pathways, oko kukuthi, i-kuyondelelaniswe kwezondlo lipid uyawongamela ekungafuneki yayo. Ngenxa ukuqhubeka sifo internal waphazamiseka ukusilela intliziyo sikhula, somnolence izigulane kunye ukudumba. rhoqo unobangela seswekile, isifo gallstone, iposi engabalulekanga, i ukutyeba.
