Xaus - systolic ntim yog cov ntshav tshuav nyob rau hauv lub ventricle ntawm lub kawg ntawm systole cov , tom qab lub plawv tau cog lus. Stroke ntim yog cov ntshav ntau uas lub plawv tso tawm ntawm sab laug ventricle nrog txhua tus ntaus. Cov mis rau stroke ntim yog: Stroke ntim = kawg - diastolic ntim – kawg - systolic ntim.
Ua kom pom qhov no, dab tsi yog qhov kawg systolic ntim?
Rau ib nruab nrab -sized txiv neej, tus kawg -diastolic ntshav siab ntim yog 120 milliliters ntshav thiab cov kawg - systolic ntim yog 50 milliliters ntawm cov ntshav. Qhov no txhais tau tias nruab nrab mob stroke ntim rau ib tug txiv neej noj qab nyob zoo yog feem ntau txog 70 milliliters ntawm cov ntshav ib zaug. Tag nrho cov ntshav ntim kuj cuam tshuam rau tus lej no.
Kuj Paub, puas yog qhov kawg systolic ntim hloov thaum lub sijhawm ua haujlwm? Cov nce nyob rau hauv arterial siab (nce ventricular afterload) uas nquag tshwm sim thaum qoj ib ce nyhav kom txo qis hauv kawg - systolic ntim ; txawm li cas los xij, qhov loj nce Hauv inotropy yog qhov tseem ceeb tshaj plaws cuam tshuam kawg - systolic ntim thiab mob stroke ntim.
Nyob rau hauv no txoj kev, yog dab tsi yog lub mis rau xam stroke ntim?
Txoj kev peb xam cov mob stroke tus nqi yog SV yog sib npaug rau EDV rho tawm ESD: SV = EDV - ESD. Yog kawg diastolic ntim yog 120 ml ntawm cov ntshav thiab qhov kawg systolic ntim nyob ib puag ncig, cia peb hais, nws yog 50 ml.
Qhov kawg systolic ntim cuam tshuam li cas rau lub plawv tso zis?
Cov stroke ntim tuaj yeem nce ntxiv, ib txwm muaj, lossis qis dua, nyob ntawm qhov hnyav ntawm AI. The LV ntim yog nce thaum lub sij hawm so ntawm isovolumic. Nyob rau hauv chronic AI lub kawg - diastolic, kawg - systolic thiab stroke ntim yog cov loj. Lub plawv tso zis yog ib txwm, txawm tias qhov contractility tsawg.

Dab tsi yog qhov sib txawv ntawm qhov kev cia siab rau qhov ntim thiab qhov ntim cia tseg?
Qhov ntim cia tseg (ERV) yog cov pa ntxiv uas tuaj yeem nqus tau tom qab ua pa ib txwm. Nws yog qhov nyiaj khaws cia uas tuaj yeem nqus tau dhau qhov uas ib txwm muaj. Hloov pauv, qhov ua rau lub zog cia siab (IRV) yog qhov ntxiv ntawm huab cua uas tuaj yeem nqus tau tom qab nqus tau ib txwm
Koj yuav pom qhov kawg nyob rau hauv qhov muaj zog titration li cas?
Hauv qhov ntsuas qhov muaj zog ntau qhov kawg tau txiav txim siab los ntawm kev siv ob qho ntawm cov hluav taws xob lossis cov hluav taws xob ua ke. Qhov kawg tshwm sim qhov twg muaj qhov siab tshaj plaws ntawm kev hloov pauv ntawm qhov muaj peev xwm ntawm qhov kawg ntawm qhov titration
Koj yuav nyeem qhov kaw qhov kawg manometer li cas?
VIDEO Ib yam li ntawd, lub manometer puas yuav ua haujlwm yog tias nws qhib kawg kaw? Siab ntawm cov pa hauv a kaw ntim sib npaug hauv txhua qhov txhia chaw. Manometers yog siv los ntsuas qhov siab ntawm cov pa hauv kaw thawv. Yog ib cov kawg yog qhib mus rau huab cua, peb hu hom no qhib manometer , thiab yog kaw , ces peb cal kaw manometer .
Dab tsi yog qhov kawg systolic ntim?
Rau ib tug txiv neej qhov nruab nrab, qhov kawg-diastolic ntim yog 120 milliliters ntawm cov ntshav thiab qhov kawg-systolic ntim yog 50 milliliters ntawm cov ntshav. Qhov no txhais tau tias qhov nruab nrab mob hlab ntsha tawg rau txiv neej noj qab haus huv feem ntau yog li ntawm 70 milliliters ntawm cov ntshav ib zaug. Cov ntshav tag nrho tseem cuam tshuam rau tus lej no
Koj xam xam ntev npaum li cas IV yuav khiav?
Cov mis los xam seb nws yuav siv sij hawm pes tsawg teev rau IV kom ua tiav ua ntej nws tag nrho yog: Lub Sijhawm (teev) = Volume (mL) Drip Rate (mL / teev). Qhov ntim ntawm cov kua yog 1000 ml thiab IV lub twj tso kua mis teeb tsa ntawm 62 mL/teev
