Systolic thiab diastolic ntshav siab

Nyob rau hauv cov ntshav siab txhais li cas volume ntawm cov ntshav pumped ib chav tsev ntawm lub sij hawm lub plawv. Heev kub siab ntawm cov ntshav yog cai thaum lub sij hawm nws tso tawm los ntawm lub plawv sab laug ventricle. Cov hlab ntsha lawv tus kheej cov ntshav siab me ntsis tsawg. Nyob rau hauv tsiv mus cov hlab ntsha yog ntxiv txo. Venous ntshav siab yog xav tau tus nqi qis tshaj, tshwj xeeb tshaj yog nyob rau kev nkag ntawm txoj cai atrium. Nyob rau hauv ntau qhov chaw ntawm peb lub cev muaj yog ib tug txawv degree ntawm cov ntshav siab. Yuav ua li cas yog lub systolic thiab diastolic ntshav siab? Yuav ua li cas yog qhov txawv ntawm lawv?

Systolic ntshav siab yog ib lub ntiv ntawm no tseem ceeb heev parameter. Qhov no qhia no qhia cov qib uas siab ntawm lub caij thaum cov compressed lub plawv mob, ua rau cov ntshav yog thawb mus rau hauv cov hlab ntsha. Qhov no kev nyeem ntawv yog kom meej ua nyob rau lub hwj chim ntawm contraction ntawm lub plawv mob.

Nyob rau hauv cov tshuaj, lub diastolic ntshav siab yog xav tau ib tug qis tooj chaw. Qhov no qhia qhia lub siab tsis rau lub sij hawm ua kom tiav so ntawm lub plawv mob. Nws yuav tsum tau muab sau tseg hais tias qhov no siab yog qhov tsawg kawg nkaus siab nyob rau hauv cov hlab ntsha. Indicators ntawm cov ntshav siab oscillation amplitudes poob tawm raws li lub zog ntawm cov ntshav txaus rau tag nrho cov hlab ntsha. Qhov tseem ceeb point yog hais tias lub capillary thiab venous siab yog yuav luag ywj siab ntawm lub plawv voj voog theem.

Systolic thiab diastolic pressures yog zoo qhov tseem ceeb thiab tseem ceeb heev qhov tseem ceeb. Yog li, tus nqi ntawm cov ntshav siab yog suav tias yog ib qho taw qhia nyob rau hauv lub 120 / 80mm.rt.st. Pom qhov sib txawv ntawm lub Upper thiab qis nqi ntawm no Performance index yog tus piv ntawm 30/40. Qhov no txawv yog feem ntau hu ua mem tes siab.

Systolic thiab diastolic ntshav siab tseem ceeb heev noj qab haus huv indicators, As, uas qhia rau hauv lub xeev ntawm kev noj qab nyob ntawm tus neeg. Yog li ntawd, rau ib txhia neeg muaj ib tug periodic ntshav siab nce txheeb ze rau lub cai. Qhov no cov tsos mob no yog hu ua tawg. Sustainable nqi ntawm cov ntshav siab readings hauv qab no ib txwm yog hu ua hypotension. Xws li ib tug txawv los ntawm cov cai yuav ua rau tus kab mob tawg los yog hypotension.

Systolic thiab diastolic ntshav siab nyob rau hauv cov neeg uas muaj hnub nyoog ntau tshaj li tsib caug xyoo, tsim nyog ib tug meej mob, vim hais tias nyob rau hauv no muaj hnub nyoog tib neeg yog tshwj xeeb yog heev raug rau txoj kev loj hlob ntawm ntau yam kab mob ntawm cov hlab plawv system. Los ntawm cov ob tsis, cov neeg laus yuav tsum tau saib xyuas zoo rau cov indicators yog lub systolic siab. Qhov siab tshaj plaws permissible txwv ntawm ib txwm siab rau cov neeg uas muaj hnub nyoog nqi yog 140 / 90mm.rt.st. Feem ntau, nyeem hauv qab no rau theem no yog xam tias yog dab tsi, tab sis yog hais tias tus diastolic ntshav siab, tsis hais hnub nyoog, muaj exceeded cov nqi nyob rau hauv 90mm.rt.st. yog vim li cas rau loj kev txhawj xeeb tshwm sim.

Ntshav siab yuav tsum tob sib haum mus rau qhov txhia qhov, raws li tej sib txawv ntawm ib tug parameter los ntawm ib tug qub nqi qhia txoj kev loj hlob ntawm ib tug kab mob. Yog hais tias koj muaj muaj ntshav siab variations, nws yog ntshaw kom tau nrog ib tug kws kho mob sai li sai tau. Tsuas yog ib tug tshwj xeeb yuav tsum tau los yog txiav txim qhov ua rau ntawm qhov hloov tus nqi thiab txoj kev ntawm nws cov tshem tawm.

Vim hais tias lub plawv yog yeej tseem zoo ib leeg hais tias thoob plaws peb lub neej yog compressed thiab decompressed, nws yuav nws thiaj li hnav tawm. Lub systolic thiab diastolic siab qhia lub xeev ntawm cov kev mob plawv, thiab tej kev yuam cai ntawm nws cov hauj lwm yuav tsum tau sai li sai tau pom vim hais tias ntawm cov tseem ceeb ntsuas.
