Kuyini umfutho wegazi?

Kuye kwasendaweni ingcindezi izitsha, umfutho wegazi ihlukaniswe yaba ezintathu izinhlobo: lwemithambo, pooling eyeqile capillary. Ngenxa yokucindezela igazi Kwenziwa ukukhuthazwa ngokusebenzisa izitsha isimiso sokujikeleza kwegazi zomzimba. Ngakho, ukuze alondoloze homeostasis futhi umzimba izinqubo therein. Arterial blood pressure kuncike ngamandla Kufinyeta senhliziyo, kanye lemali yegazi uyakhishwa ngesikhathi systole. okumqoka iyona viscosity wegazi ezingeni kwesifuba nesisu, kanye lemali yegazi ukhiphela umzimba.

Phakathi ukusikwa i-ventricle engakwesobunxele wenhliziyo lwemithambo blood pressure ifinyelela seqiwe. Ngalesi sikhathi inhliziyo iphampa mayelana 70 cm3 kwegazi. Yiqiniso, lokhu kwasusa esikhulu yenqwaba igazi okungakwazi ngokushesha idlule imithambo yegazi esihle futhi kuma-capillary, ngakho yomthambo i-aorta odongeni elula, ngalesi sikhathi, ingcindezi therein kwandisa. Jwayelekile igazi ingcindezi (systole) zokhahlamba kusuka 100 kuya 140 mm HG. ikholomu.

ingcindezi diastolic Kumiswa ngokunciphisa odongeni le-aorta nokuvaleka kwemithambo emikhulu. Ngakho, igazi bafakwa capillary igazi. Kulesi blood pressure kancane kancane kunciphisa futhi cishe 70-80 mm HG. ikholomu. Kufanele ukuthi ingcindezi igazi izitsha incike ibanga abo maqondana nenhliziyo, ziqhubeka bavela inhliziyo, ngaphansi kwabo blood pressure ukufundwa. Ukuze sithole blood pressure ezingeni sfingomanometr ukusetshenziswa kwezokwelapha.

Isizathu esikhulu nomfutho wegazi ophezulu (high blood pressure) , ochwepheshe abaningi bakholelwa ngokomzwelo kakhulu, iloli sezinzwa, ukucindezeleka ngokomzwelo nezinye ukucindezeleka psycho-ngokomzwelo. It Ukuphahlazeka e isimiso sezinzwa ahambisana ukwanda komthwalo ingcindezi anterialnym. Iziguli ukuthi nginesifo umfutho ophakeme wegazi, blood pressure inyuka ngokushesha futhi ihlala isikhathi eside, nokucindezeleka kancane psycho-ngokomzwelo, uma kuqhathaniswa nabantu enempilo. Ngakho, waba ukwanda ehlelekile wegazi, umzimba wethu Ufika esetshenziswa, ingashintshwa ukuze umthwalo idatha, umfutho wegazi ophakeme eqondiswa ezingeni elithile. Lo mbuzo ubuzwa - kufanele kube igazi evamile ingcindezi. Norma ke ikakhulu incike izici ngamunye bokuphila komuntu, ubudala, yokuphila, imisebenzi ngokomzimba, njll Ngokwesibonelo, entsheni ingcindezi kufanele 100/70, futhi ngonyaka ka-60 ubudala, kuba - 150/90 mm HG. Art.

Isici esibalulekile ekuthuthukiseni nomfutho wegazi ophezulu yilezi izifo kwezinso, bona iqhaza ukulawulwa blood pressure (ukukhiqiza ethize, kwakwakhe eziphila abakhuthele). Lapho sezinso Kwabiwa indlela iphazamisekile excreted NaCl, futhi, ukuze kuvuswe blood pressure ezaziwayo. Okubi nakakhulu, uma umfutho wegazi ophakeme kuba amahlala khona. Le nkathi libhekene esitebeleni ukunyuka komfutho wegazi (hypertension), umzimba lesiguli uvuma imithwalo ekhona, kudala umbono zamanga mayelana inhlalakahle, ukuthi, isiguli cishe engazizwa ubuhlungu, futhi ngenxa yalokho, ayisekho ngayo.

Ukwazi indlela yalesi sifo ukuthuthukiswa ke zingalawulwa. Ukuze wenze lokhu, kumele uthobele yonke izincomo likadokotela, ukuqhuba umbuso ngokuhleleka ukuphumula kanye nomsebenzi, ukunciphisa umfutho pisihoemotsionalnogo ukucindezeleka emzimbeni. Isebenza kuhle nxa nomfutho wegazi ophezulu odokotela linqume izidakamizwa futhi zibe nethonya sine. ukhuluphele abanomfutho wegazi ophakeme tekuvikela kufanele kube ukunciphisa umzimba. Hypertension is kwehlisa kahle nge ngokweqile. Ukukhuluphala libhekisela ukuhlukumeza izinqubo umzimba, okungukuthi, synthesis kwezakhi lipid ubusa ngaphezu nokwahlukana yayo. Nge ukuqhubeka kwesifo kuyinto kwezimila okhathazekile futhi senhliziyo sikhula, iziguli somnolence nokuvuvukala. Umbhali wayevame ukunezela lokhu imbangela isifo sikashukela, isifo gallstone, isilethikusebenza, kuyinto ukukhuluphala.
