Xa intliziyo yakho igxotha igazi kwimibhobho yakho, iphosa igazi phantsi kwentloko yoxinzelelo. Oogqirha balinganisa uxinzelelo lwegazi njengendlela yokuqikelela amandla osebenzayo ngeli gazi elihambayo kwiindonga zemibhobho yakho.
Ngenxa yokuba intliziyo iyabetha, igazi eligeleza kwimibhobho ayigxininisekanga (njengombhobho womlilo), kodwa i-pulsatile, kunye nokuhamba kwegazi, kunye neengcinezelo ezikhoyo, ukutshintsha ukusuka kwesikhashana ukuya kumzuzwana.
Ngenxa yoko, ukulinganisa kwegazi lomntu kubhalwe njengamanani amabini ahlukeneyo - uxinzelelo lwegazi lwe-systolic kunye noxinzelelo lwegazi lwe-diastolic. La manani amabini abonakalisa imiba eyahlukileyo yoxinzelelo oluqhutyelwa igazi lakho njengoko liphuma kwimibhobho yakho.
Ukufunda kwakho uxinzelelo lwegazi kubhalwe ngale ndlela: 120/80; kwaye ithetha kanje: "120 ngaphezulu kwama-80." Ukufunda kwengcinezelo yegazi ye-systolic inani eliphezulu, kunye nokufundwa kwengcinezelo yegazi ye-diastolic yincinci ephantsi.
Ezi zombini ixabiso limelela uxinzelelo ngaphakathi kwemibhobho yakho ebonakaliswe kwimilimitha ye-mercury, okanye i-mmHg.
Zibini ezibalulekileyo iimpempo ze-systolic kunye ne-diastolic. Ukuba ukufundwa kukuphakamileyo, ingozi yexinzelelo ingase ibe khona. Ukuba ukufundwa kwengcinezelo yegazi kuphantsi kakhulu, kunokungenakho ukugeleza kwegazi kumalungu angundoqo, njengengqondo.
Yintoni Ixinzelelo Lwegazi?
Uxinzelelo olwenziwa ngegazi lakho eligelezayo kwimibhobho yakho ayisoloko ihlala, kodwa lugxininisa kwaye luhlala lubonisa oko intliziyo eyenzayo ngexesha elithile.
Xa intliziyo ibetha ngamandla (isiganeko esibizwa ngokuthi "systole"), ilahla igazi lingena kwimibhobho. Ukunyuka kwegazi okunamandla kumathambo kubangela ukuba uxinzelelo phakathi kwemibhobho luvuke. Ingcinezelo yegazi ifikelele ngexesha lokuqhekeka kwenhliziyo ebizwa ngokuba yi-systolic blood pressure.
Uxinzelelo lwegazi lwe-systolic "oluqhelekileyo" xa umntu ehleli ngokuzithele ngo-120 mmHG okanye ngaphantsi.
Xa umntu eqhuba, ngexesha lokuxinzezeleka kwengqondo, okanye nangaliphi na ixesha xa intliziyo ikhuthazwa ukubetha ngakumbi ngaphezu kokuphumla, amandla okweqanda kwentliziyo ayenyuka-kwaye ukunyanzeliswa kwe-systolic kuya kunyuka. Ukwanda kwenycinezelo yegazi ye-systolic eyenzekayo kule miqathango yokuxinzezeleka kwengqondo yinto eqhelekileyo.
Oku kuchaza ukuba kubaluleke kangakanani ukulinganisela uxinzelelo lwegazi ngexesha lokuphumla okuphumlileyo ngaphambi kokuba ufumane ingozi yokunyamezela .
Ukuba umxinzelelo wegazi we-systolic ungaphantsi kuneqhelekileyo, kuthiwa ukhona. Ukuba i hypotlic hypotension yomelele ngokwaneleyo, inokubangela ukukhanya okukhawulezayo , utywala , i- syncope , okanye (ukuba ihlala ixesha elide ngokwaneleyo), ukusilela komzimba. I-hypotension ye-Systolic inokwenzeka xa umthamo wegazi uhlahla kakhulu (njengokuba utyhefu oluninzi okanye i-episode ephambili yegazi), ukuba isifo senhliziyo siba buthathaka kakhulu ukukhipha igazi ngokuqhelekileyo (imeko eyaziwa ngokuba yi- cardiomyopathy ), okanye ukuba imithwalo yegazi ibe ihlanjululwe (njenge- vasovagal syncope ). Umqathango oqhelekileyo ovelisa i-systolic hypotension yi- orthostatic hypotension .
Yintoni i-Diastolic Blood Pressure?
Uxinzelelo lwegazi lwe-diastolic luxinzelelo lwegazi luphakathi kweemibhobho phakathi kweentliziyo, oko kukuthi, xa intliziyo ingenayo igalelo legazi kwiimithambo.
Emva kokuba intliziyo igqityiwe, i-cardiac ventricles iphumula okwesikhashana ukuze ikwazi ukuzaliswa ngegazi, ekulungiseleleni ukulandelana okulandelayo. Eli thuba lokuphumula ngokwemvelo libizwa ngokuthi "i-diastole," kwaye uxinzelelo lwegazi ngexesha le-diastole libizwa ngokuba yi-diastolic blood pressure.
Uxinzelelo "lweqhelekileyo" lwe-diastolic yegazi ngexesha lokuphumula ukuphumula ngu-80 mmHG okanye ngaphantsi. Kwixinzelelo legazi, uxinzelelo lwegazi lwe-diastolic luvame ukwanda ngexesha lokuphumla okuphumlileyo. I-diastolic hypotension (xa i-diastolic yexinzelelo yegazi iphantsi) ingabonwa ngokuphelelwa umdaka okanye ngokuphuma kwamagqabi, okanye ukuba iirriyiti zihlanjululwa ngokwemvelo.
Kubaluleka kokulinganisa uxinzelelo lwegazi ngexesha lokuphumla komzimba
Ingcinezelo yegazi yinto enamandla kakhulu. Umgangatho wexinzelelo lwegazi uxhomekeke kwimisebenzi yentliziyo yakho kunye ne-elasticity of arteries yakho. Njengoko sibonile, uxinzelelo lwegazi luguquka ngokukhawuleza ukususela emzuzwana ukuya kwangoko njengoko intliziyo ijikeleza phakathi kwe-systole kunye ne-diastole.
Ukongezelela, uxinzelelo lwegazi lwe-systolic kunye ne-diastolic (oluphezulu kunye noxinzelelo lwegazi oluphantsi kakhulu lufikeleleki ngexesha leyiphi na umjikelezo wenhliziyo) lunokutshintsha kakhulu ukususela ngomzuzu ukuya kumzuzu kuxhomekeke kwimeko yakho yomsebenzi, imeko yakho yokuxinezeleka, isimo sakho se-hydration, kunye nezinye izinto.
Oko kuthetha ukuthini ukuba, ukuze uhlolisise i-hypertension ngokuchanekileyo, kubalulekile ukulawula ezininzi "izinto zangaphandle" izinto ezinokwenzeka. Umgangatho ophakanyiswe ngugqirha ufuna ukuba uxinzelelo lwegazi lugcinwe kwindawo ezolile, efudumalayo emva kokuphumla ngokuzenzekileyo ngethuba ubuncinane imizuzu emihlanu. Ukulinganisa uxinzelelo lwegazi ngale ndlela kuyinselelo kwiofisi yezobugqirha, ngokuxilongwa ngokuchanekileyo kwengcinezelo yecembelelo engakumbi kunzima. Yingakho iingcali ezininzi namhlanje zincoma ukurekhoda uxinzelelo lwegazi ngaphezu kwexesha elongezelelweyo, kunye nokubeka iliso kwi-ambulatory, ngaphambi kokuba kwenziwe i-diagnostic ye-hypertension.
ILizwi
Ukunyanzelwa kwegazi nge-Systolic kunye ne-diastolic kubonisa iingcinezelo kwimida yegazi ngexesha leemeko ezahlukeneyo zomjikelezo wenhliziyo. Ukulinganisa ngokuchanekileyo kwezi zibini kubalulekile ekuhloleni nasekulawuleni umfutho wegazi ophezulu.
