Myocardial cov ntaub so ntswg perfusion yog myocardium lub peev xwm los rho cov pa thiab cov as-ham los ntawm cov hlab ntsha. Kev saib xyuas ntawm ib txwm muaj peev xwm nyob ntawm cov hlab ntsha ntawm cov hlab ntsha, tsis muaj stenosis, ntxiv rau arterial oxygen cov ntsiab lus, ntshav ntim, plawv tso tawm, thiab ntev ntawm diastole (Braunwald, 2005).
Hais txog qhov no, lub ntsiab lus ntawm cov ntaub so ntswg perfusion yog dab tsi?
Perfusion yog cov kua dej nkag mus rau hauv lub circulatory system los yog lymphatic system mus rau lub cev los yog a cov ntaub so ntswg , feem ntau yog xa mus rau kev xa cov ntshav mus rau lub txaj capillary hauv cov ntaub so ntswg.
Tom qab ntawd, lo lus nug yog, koj yuav tshuaj xyuas cov ntaub so ntswg li cas? Cov ntaub so ntswg perfusion . Kev ntsuam xyuas ntawm cov ntaub so ntswg perfusion tuaj yeem ua tiav los ntawm kev txiav txim siab cov pos hniav lossis daim di ncauj mucous xim, lub sijhawm capillary refill, thiab ntshav siab. Siab siab cov hlab ntshav siab tsis lav tias tsim nyog cov ntaub so ntswg perfusion.
Tom qab ntawd, dab tsi ua rau cov ntaub so ntswg perfusion?
Ntau yam xwm txheej tuaj yeem cuam tshuam kev sib pauv ntawm cov pa oxygen thiab carbon dioxide, tab sis ntshav qab zib, rog rog, anemia, ntshav siab, thiab kab mob coronary artery yog qee yam kev pheej hmoo ntau dua uas tuaj yeem ua tau. ua tsis muaj txiaj ntsig cov ntaub so ntswg perfusion.
Dab tsi yog perfusion ntawm lub siab?
Myocardial perfusion yog ib qho kev kuaj duab. Nws tseem hu ua kev sim ntsuas kev ntxhov siab nuclear. Nws tau ua tiav los qhia seb cov ntshav ntws zoo li cas plawv nqaij. Nws kuj qhia tau hais tias zoo npaum li cas plawv cev nqaij daim tawv. Piv txwv li, tom qab a plawv kev tawm tsam, nws tuaj yeem ua kom pom thaj chaw puas plawv nqaij.

Vim li cas cov ntaub so ntswg perfusion tseem ceeb?
Kev tsim cov ntaub so ntswg txaus thiab oxygenation yog qhov tseem ceeb rau txhua qhov txheej txheem hauv lub cev thiab qhov cuam tshuam loj ntawm kev kho cov ntaub so ntswg thiab tiv thaiv kab mob sib kis
Yam dab tsi cuam tshuam rau cov ntaub so ntswg perfusion?
Tissue Perfusion: Lub plawv dhia tawm ntawm lub plawv yog nyob ntawm lub plawv dhia thiab mob stroke. Qhov ntim ntawm cov hlab ntsha yuav cuam tshuam los ntawm kev thauj khoom ua ntej (ntim siab), tom qab thauj khoom (systolic tsis kam), thiab kev cog lus (quab yuam ntawm kev sib zog). Lub plawv dhia yog nyob ntawm kev sib koom siab thiab parasympathetic sib npaug
Dab tsi yog qhov sib txawv ntawm cov ntaub so ntswg sib txuas tsis tu ncua thiab cov ntaub so ntswg sib txuas tsis sib xws?
Cov ntaub so ntswg sib txuas tsis sib thooj muaj cov fibers uas tsis tau sib dhos ua ke zoo ib yam li cov ntaub so ntswg sib txuas ib ntus. Cov ntaub so ntswg sib txuas tsis sib thooj muaj feem ntau ntawm cov fibers collagen. Nws muaj cov khoom hauv av tsawg dua li cov ntaub so ntswg sib txuas
Hom ntaub so ntswg sib txuas twg yog cov ntaub so ntswg?
Cov ntaub so ntswg reticular yog ib hom tshwj xeeb ntawm cov ntaub so ntswg sib txuas uas muaj nyob hauv ntau qhov chaw uas muaj cov ntsiab lus ntawm tes. Nws muaj ib tug ceg thiab mesh-zoo li tus qauv, feem ntau hu ua reticulum, vim yog kev npaj ntawm reticular fibers (reticulin). Cov fibers no yeej yog hom III collagen fibrils
Cov ntaub so ntswg yog dab tsi thiab muaj pes tsawg hom ntaub so ntswg?
Cov ntaub so ntswg yog ib pawg ntawm cov cell uas muaj cov duab zoo sib xws thiab ua haujlwm. Cov ntaub so ntswg sib txawv tuaj yeem pom hauv cov kabmob sib txawv. Hauv tib neeg, muaj plaub yam tseem ceeb ntawm cov ntaub so ntswg: epithelial, txuas, leeg, thiab leeg nqaij. Tej zaum yuav muaj ntau cov ntaub so ntswg hauv txhua qhov ntawm cov ntaub so ntswg
