Mob ntsws ntshav siab feem ntau qis dua li cov ntshav siab . Cov hlab ntsws loj li qub yog 8-20 mm Hg ntawm so. Yog tias siab hauv pulmonary leeg ntau dua 25 mm Hg ntawm so lossis 30 mmHg thaum ua haujlwm lub cev, nws txawv txav heev thiab hu ua ntsws ntshav siab.
Tsis tas li, dab tsi yog qhov ua pa ntawm cov hlab ntsws ib txwm los ntawm ncha?
Pulmonary Hypertension Echocardiography. Cov hlab ntshav hlab ntshav ib txwm muaj nyob hauv tus neeg nyob ntawm theem hiav txwv muaj tus nqi nruab nrab ntawm 12-16 mm hli . Pulmonary hypertension yog tam sim no thaum txhais tau tias pulmonary artery siab tshaj 25 mm hli thaum so lossis 30 mm hli nrog kev qoj ib ce.
Tom qab ntawd, lo lus nug yog, koj yuav ntsuas ntshav siab li cas? Nws tau dav lees tias txhais tau tias pulmonary artery pressure (mPAP) yuav raug kwv yees kom raug los ntawm kev siv tus qauv mis : mPAP = 2/3 dPAP + 1/3 sPAP, qhov twg dPAP yog diastolic pulmonary artery siab , thiab sPAP yog systolic pulmonary artery siab.
Tsuas yog li ntawd, dab tsi yog qhov txwv qis tshaj ntawm qhov ib txwm txhais tau tias yog cov hlab ntshav siab?
Taw qhia. Ib txwm txhais tau tias yog cov hlab ntshav hlab ntshav siab (mPAP) yog 14 ± 3 mmHg nrog rau siab tshaj ntawm 20 mmHg [1]. Tam sim no, hemodynamic txhais ntawm ntsws ntshav siab (PH) yog mPAP ≧ 25 mmHg ntawm qhov so thaum ntsuas cuam tshuam los ntawm txoj cai plawv catheterisation (RHC) [2, 3].
Koj yuav ntsuas tus mob ntshav siab li cas hauv Echo?
Kom muaj nuj nqis pulmonary hypertension nrog echocardiography nws yog qhov yuav tsum tau ntsuas qhov siab tshaj plaws tricuspid regurgitation nrawm nrog CW Doppler. Yog li, ntsws kev nyuab siab tuaj yeem tau txais tsuas yog thaum muaj qhov ntsuas tau TR teeb liab.

Dab tsi yog qhov sib txawv ntawm tunica media hauv cov hlab ntshav piv rau tunica media hauv cov leeg?
Cov hlab ntsha tsis tau ntsib qhov nrawm nrawm uas cov hlab ntsha ua. Yog li ntawd, lawv tsis tas yuav tsum muaj cov txheej txheem muaj zog, thiab lawv tsis yog. Lub nkoj cov phab ntsa ntawm cov hlab ntshav yog nyias dua cov hlab ntsha thiab tsis muaj ntau npaum li tunica media. Cov xov xwm tunica me me cuam tshuam nrog lub lumen ntau dua hauv cov hlab ntsha
Dab tsi yog qhov txiaj ntsig ib txwm rau PaO 2 Dab tsi yog qhov txiaj ntsig rau kev txiav txim siab qhov hnyav ntawm hypoxemia?
Zoo li feem ntau qhov kev kho mob ib txwm muaj txiaj ntsig thiab ntau yam, lub ntsiab lus tuaj yeem sib txawv me ntsis, tab sis feem ntau cov ntsiab lus hauv qab no siv: Ua rau me me hypoxemia: PaO2 = 60 txog 79 mmHg. Qhov nruab nrab hypoxemia: PaO2 = 40 txog 59 mmHg. Hypoxemia hnyav: PaO2 <40 mmHg
Yam kev pheej hmoo dab tsi rau CVD feem ntau txiav txim siab los ntawm cov kws kho mob thaum ntsuas lawv cov neeg mob?
Xws li Kab Mob: Lub plawv tsis ua hauj lwm; Coronary artery disease
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
Dab tsi ua rau cov ntshav siab ferritin ntau ntau?
Piv txwv li, lub siab lub hlwb tau khaws cia ferritin.Qhov feem ntau ua rau siab ferritin ntau ntau yog rog rog, o, thiab haus cawv txhua hnub. Feem ntau ua rau muaj caj ces ntsig txog kev nce qib ferritinlevels yog mob hemochromatosis
