Kev kuaj lub cev feem ntau tuaj yeem txheeb xyuas qhov chaw ntawm arterial occlusion . Cov classic mnemonic rau arterial occlusion yog " rau ps ": mob, pulselessness, pallor, tuag tes tuag taw, paresthesia, thiab poikilothermia. Qhov cuam tshuam ntawm ceg, nrog rau qhov tsis sib haum xeeb, yuav tsum tau kuaj xyuas pulses.
Tib neeg tseem nug, 6 P's cuam tshuam nrog cov tsos mob ntawm cov hlab ntsha puas ntsoog?
Qhov kev nthuav qhia classic ntawm limb ischemia yog lub npe hu ua " rau ps , " pallor, mob, paresthesia, tuag tes tuag taw, pulselessness, thiab poikilothermia. Cov kev kho mob tshwm sim tuaj yeem tshwm sim nyob txhua qhov chaw mus rau qhov occlusion. Feem ntau cov neeg mob pib muaj mob, pallor, pulselessness, thiab poikilothermia.
Koj ntsuas arterial insufficiency li cas? Muaj ntau qhov kev ntsuas thiab ntsuas ntsuas muaj los kuaj xyuas arterial insufficiency , qhov yooj yim ntawm uas yog ib qho kev ntsuam xyuas ntawm peripheral pulses nyob rau hauv ob qho tib si extremities. Qhov tsis muaj palpable mem tes yuav tsum tau ua raws li kev soj ntsuam rhiab ntau dua, suav nrog kev siv Doppler ultrasound.
Kuj paub, 5 P's ntawm ischemia yog dab tsi?
Tsoos 5p s ua ntawm mob ischemia nyob rau hauv lub limb (piv txwv li, mob, paresthesia, pallor, pulselessness, poikilothermia) yog tsis kho kom zoo; Lawv tuaj yeem tshwm sim tsuas yog nyob rau theem kawg ntawm kev sib koom ua ke syndrome, los ntawm lub sijhawm uas nws yuav tshwm sim los ntawm cov ntaub so ntswg uas tsis muaj kev puas tsuaj.
Dab tsi ua rau cov hlab ntsha tsis txaus?
Ib qho ntawm feem ntau ua rau arterial insufficiency yog atherosclerosis los yog "hardening ntawm cov hlab ntsha." Cov khoom rog (hu ua cov quav hniav) ua rau phab ntsa ntawm koj cov hlab ntsha. Qhov no ua rau lawv nqaim thiab tawv. Vim li ntawd, nws nyuaj rau cov ntshav ntws los ntawm koj cov hlab ntsha.

Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Vim li cas peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
Cov leeg yuav tsum tau li qub kom cov ntshav ntws mus rau lub plawv. Theses li qub yog qhov tshwj xeeb hauv ob txhais ceg thiab caj npab. Lawv tawm tsam lub ntiajteb txawj nqus los tiv thaiv cov ntshav rov qab los. Cov hlab ntsha tsis xav tau li qub vim tias lub siab los ntawm lub plawv ua kom cov ntshav ntws los ntawm lawv mus rau ib qho
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
Dab tsi yog peb hom hlab ntsha hauv cov hlab ntsha?
Muaj peb yam tseem ceeb ntawm cov hlab ntsha: cov hlab ntsha. Lawv nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau tag nrho lub cev cov ntaub so ntswg. Capillaries. Cov no yog cov hlab ntshav me me, uas txuas cov hlab ntsha thiab cov leeg. Cov leeg
