Ingcindezi evamile ingu-140 kuya ku-90.

Enye yezinkomba ezihamba phambili zesimo sempilo yabantu, esivame ukusetshenziselwa umkhuba kadokotela, izinga legazi.

Leli zinga lenziwa yisenzo sezitho ezihlukahlukene nezinhlelo. Okokuqala - uhlelo lwezinhliziyo. Ithembo le-vascular and heart rate lilawulwa yizinhlelo ze-nervous and humoral. Ngokukhathazeka kwemizwa (imizwelo, ukucindezeleka), izinga lenhliziyo landa. Ukukhululwa egazini le-adrenaline kunqunywa ohlelweni oluhlelekile. Ngaphezu kwalokho, ezinye izinto eziningi ezingaphandle zithinta izinga legazi lethu.

Ngokuvamile kucatshangwa ukuthi ingcindezi evamile ingama-140 kuya kwangu-90 noma ngaphansi. Inani eliphakeme lingase likhulume nge- hypertension, lapho kwenzeka ukuthi leli zinga eliphakeme liphikelela.

Ngaphambili odokotela baqinisekisa, ukuthi ukucindezeleka kuka-140 kwabafundi abangu-90 - izibalo eziphakeme kakhulu. Noma kunjalo, okwamanje akukho ukuhlukaniswa okuphawulekayo okwenziwe futhi ukucindezelwa okuvamile kumadoda kufana nokwabesifazane.

Ngifuna ukuqaphela ukuthi ukucindezela okujwayelekile komuntu kanye ne-pulse kuhlobene. Ngakho, ngokunyuka kwentengo yenhliziyo (ukwanda kwenani lenhliziyo), ukucindezeleka kwegazi kuphakama. Kodwa ukunyuka kwengcindezi egazini akusho ukuthi ukushayela kuyoba njalo.

Iziphi izifo noma izimo zokugula ezingathinta inkomba enjalo njengengcindezi evamile (140 kuya ku-90)? Lezi zihlanganisa izifo zesimiso senhliziyo (ngokwaso ukuqina kwesifo sobuthakathaka) kanye nezifo zezinye izinhlelo. Lokhu kungaba yinkinga yokulawulwa kwemizwa, kanye nokuphulwa komthetho we-endocrine (humoral).

Ukuxilongwa kokucindezeleka komzimba kwenziwa ngokukala izinga legazi nge tonometer. Uma kwenzeka uma uvakashele udokotela kathathu (ikhefu phakathi kokuvakasha okungenani ngesonto elilodwa), isibonakaliso singaphezu kuka-140 kuya kwezingu-90 sidlulile - ukutholakala kwesifo somfutho wegazi kuyasethiwe.

Lesi simo sibonakala njengenhloko (ikakhulukazi esifundeni se-occipital) nesizungu, umsindo ekhanda, ukukhanya kwezimpukane phambi kwamehlo. Ngaphezu kwalokho, isiguli sizwa isifo senhliziyo esiqinile. Ngomfutho wegazi ophezulu, isicanucanu nokuhlanza kungenzeka.

Ukwelashwa akuqali ngokusetshenziswa kwemithi (izidakamizwa), kodwa ngokulahla imikhuba emibi (ukubhema nophuzo) nokuhambisana nokudla okuqinile. Isimiso esiyinhloko sokudla komfutho wegazi ophakeme kungumkhawulo wesinkwa esidliwe ekudleni. Lesi simiso sisiza ukunciphisa ukugcinwa kwamanzi emzimbeni, okuvame ukusiza ukunciphisa ingcindezi. Ngaphezu kwalokho, ukudla okusawoti kunciphisa umthwalo ezinsweni futhi kunciphisa ukukhukhumeza (uma kukhona).

Endabeni lapho impilo yokuphila enempilo nokudla okusawoti kungaholela ekwehlisweni okudingekile kwengcindezi, odokotela basebenzisa ukubeka izidakamizwa. Ukuqhathaniswa kokwelashwa kwalesi sifo ukuqokwa kwezinto eziyinkimbinkimbi zezidakamizwa ukufeza umphumela oyifunayo. Ngaphezu kwalokho, ukusetshenziswa kwale mithi kufanele kuhleleke futhi kube njalo.

Njengoba kushiwo ngenhla, ingcindezi engu-140 kuya kwezingu-90 ibhekwa njengomkhawulo ophezulu wejwayelekile, futhi, kuye ngokuthi izinga elingaphezu kwalesi silinganiso esingaphezulu, amazinga amathathu e-hypertension ahlukile. Kwelinye iqembu elihlukile elikhuliswe ngokweqile kuphela ukwanda kwengcindezi ye-diastolic, okukhulunywa kakhulu kaningi ekuguleni kwezinso (ngoba yizinso ezilawula enye yezinhlelo zokulawulwa kwegazi - uhlelo lwe-renin-angiotensin-aldosterone). Isici esimangazayo sehlobo lokugcina lokushisa kakhudlwana kungukungabikho kwemizwa yokucindezela okwandayo, okungukuthi, iziguli zizwa kahle futhi azikhalazi.
