Koj puas tau nres thiab xav txog seb cov ntshav mus los ntawm koj lub siab mus rau txhua lub ces kaum ntawm koj lub cev, mus txog koj cov ntiv tes li cas? Nws zoo li ib txoj kev sib txuas ntawm txoj kev hauv nroog. Qee qhov chaw, tsheb khiav mus zoo, qee qhov chaw, nws muaj neeg coob heev, thiab qee qhov chaw, txoj kev nqaim. Cov ntshav ntws hauv peb lub cev zoo ib yam. Hauv kev kho mob, peb hu cov ntshav ntws no, cov zog uas cuam tshuam rau nws, thiab cov txheej txheem uas nws mus dhau, 'hemodynamics.' Tsis txhob txhawj, lub npe yuav zoo li nyuaj me ntsis, tab sis zaj dab neeg yooj yim heev. Cia peb tham txog nws.
Dab tsi yog hemodynamics tiag tiag?
Hauv lwm lo lus, hemodynamics yog kev kawm txog seb cov ntshav ntws li cas los ntawm koj cov hlab ntsha thiab cov leeg ntshav thiab ntau yam zog uas cuam tshuam rau cov ntshav ntws ntawd.
Feem ntau, cov ntshav ntws hauv cov hlab ntsha ntawm tus neeg noj qab haus huv hauv tus qauv du thiab zoo. Peb hu qhov no ua laminar flow . Ib yam li dej ntws los ntawm cov yeeb nkab, cov ntshav txav mus sai tshaj plaws hauv nruab nrab ntawm cov hlab ntsha vim tias muaj kev sib txhuam me ntsis nrog cov phab ntsa.
Txawm li cas los xij, sab hauv cov chav qis ntawm koj lub plawv (peb hu cov no ua ventricles ) thiab qhov twg cov hlab ntsha ceg, lossis qhov twg cov hlab ntsha nqaim tam sim ntawd, txoj kev taug kev no dhau los ua qhov tsis meej pem me ntsis. Peb hu qhov no ua qhov ntws tsis meej pem . Hauv txoj kev taug kev tsis meej pem zoo li no, nws siv zog ntau dua los thawb cov ntshav mus tom ntej.
Cov hlab ntsha me me uas tawm ntawm koj lub aorta xa cov pa oxygen thiab cov as-ham mus rau txhua lub cell thiab cov nqaij hauv koj lub cev. Tom qab khaws cov pa oxygen los ntawm koj cov kabmob, cov ntshav rov qab mus rau koj lub plawv los ntawm cov leeg ntshav. Lub plawv mam li tso cov ntshav mus rau koj lub ntsws, qhov chaw uas nws khaws cov pa oxygen dua, thiab lub voj voog pib dua.
Xav txog tias muaj tej yam cuam tshuam rau txoj kev uas cov ntshav no mus ncig.
- Qee zaum cov roj cholesterol uas nyob hauv cov hlab ntsha (plaque) yuav tsim rau ntawm cov phab ntsa ntawm cov hlab ntsha, ua rau cov "speed bumps." Cov no ua rau txoj kev ntshav ntws nqaim. Qee zaum cov no yuav tawg thiab thaiv cov hlab ntsha tag.
- Tsis tas li ntawd xwb, cov ntshav txhaws tuaj yeem tsim thiab thaiv cov hlab ntsha.
- Los yog tej zaum koj lub plawv tsis muaj zog thiab tsis tuaj yeem tso ntshav txaus rau koj lub cev.
Tej teeb meem no tuaj yeem ua rau peb lub cev ntshav tsis ua haujlwm zoo, uas txhais tau tias nws tsis tuaj yeem xa cov pa oxygen thiab cov as-ham uas txhua lub cell hauv lub cev xav tau.
Vim li cas nws thiaj li tseem ceeb heev kom paub txog hemodynamics?
Kev nkag siab txog cov ntshav khiav yog ib qho tseem ceeb heev, vim tias los ntawm nws koj tuaj yeem nkag siab zoo dua txog koj tus kab mob plawv lossis cov mob ntawm cov hlab ntsha.
Piv txwv li, xav txog koj muaj ntshav siab. Thaum koj kawm txog hemodynamics, koj nkag siab tias thaum lub siab nce siab, lub plawv yuav tsum ua haujlwm hnyav dua los tso ntshav. Tom qab ntawd, tus kws kho mob yuav muab tshuaj rau koj uas ua rau cov hlab ntsha dav dua (so) thiab tsim kom muaj chaw ntau dua rau cov ntshav ntws. Tom qab ntawd, lub nra hnyav ntawm lub plawv txo qis, thiab lub siab raug tswj.
Koj tus kws kho mob siv cov ntaub ntawv hemodynamics los pab kuaj mob thiab kwv yees yav tom ntej ntawm ib yam kab mob. Piv txwv li, lawv tuaj yeem kuaj xyuas seb lub plawv valve puas xau, uas tuaj yeem tiv thaiv cov ntshav kom tsis txhob ntws zoo. Lawv kuj tuaj yeem kuaj xyuas seb koj cov ntshav ntws puas tau zoo dua tom qab phais lossis noj tshuaj.
Kev ntsuas ntshav tsis yog hais txog kev ntshav siab xwb. Kev ntshav siab tsuas yog ib feem ntawm cov txheej txheem no xwb. Muaj ntau lwm yam uas cuam tshuam rau txoj kev uas peb cov ntshav ntws.
