Lim ntshav plethysmography

Limb plethysmography yog qhov kev ntsuas uas sib piv cov ntshav siab hauv ob txhais ceg thiab caj npab.

Qhov kev ntsuas no muaj peev xwm ua tau hauv tus kws kho mob lub chaw haujlwm lossis hauv tsev kho mob. Koj yuav raug hais kom pw nrog sab saud ntawm koj lub cev tsa me ntsis.

Kev ntsuam xyuas sau cov kev mob siab tshaj plaws tsim tawm thaum lub plawv cog lus (systolic ntshav siab).

Qhov sib txawv ntawm cov pulses raug sau tseg. Yog tias muaj qhov txo qis hauv cov mem tes ntawm caj npab thiab txhais ceg, nws yuav qhia tias txhaws.

Thaum qhov ntsuas tiav tiav, cov ntshav siab tuaj yeem tawm.

Yuav tsum muaj tsawg dua li 20 mus rau 30 hli Hg sib txawv hauv systolic ntshav siab ntawm txhais ceg piv nrog rau ntawm txhais caj npab.

Qhov ntsuas tsis zoo yuav yog vim:

• Arterial occlusive disease
• Cov ntshav txhaws
• Hloov ntshav hlab ntsha vim muaj ntshav qab zib
• Raug mob rau cov leeg ntshav

Tsis muaj kev pheej hmoo.

Qhov kev kuaj no tsis muaj tseeb raws li cov leeg ntshaus. Plethysmography tuaj yeem ua tiav rau cov neeg mob hnyav heev uas tsis tuaj yeem mus rau ntawm cov hlab ntshav liab. Kev ntsuam xyuas no tuaj yeem siv los kuaj xyuas vascular lossis ua raws li cov kev sim ua ntej dhau los.

Qhov kev kuaj tsis yog qhov tseeb, thiab nws tsis siv duab xoo lossis txhaj tshuaj zas xim. Nws tseem pheej yig dua li angiogram.
