Imilenze yesithombiso

I-Limb plethysmography luvavanyo oluthelekisa uxinzelelo lwegazi emilenzeni nasezingalweni.

Olu vavanyo lunokwenziwa kwiofisi yomboneleli wezempilo okanye esibhedlele. Uya kucelwa ukuba ulale nenxalenye ephezulu yomzimba wakho iphakanyiswe kancinci.

Zintathu okanye zine iikhofu zoxinzelelo lwegazi zisongelwe zazijikeleza ingalo nomlenze wakho. Umboneleli uphembelela iicuffs, kwaye umatshini obizwa ngokuba yi-plethysmograph ulinganisa iipulses ezivela kwikofu nganye. Uvavanyo lurekhoda uxinzelelo oluphezulu oluvelisiweyo xa kukho izivumelwano zentliziyo (uxinzelelo lwegazi lwe-systolic).

Umahluko phakathi kwempuluswa kuqatshelwe. Ukuba kuncipha ukubetha kwentliziyo phakathi kwengalo nomlenze, oko kunokubonisa ukuvaleka.

Xa uvavanyo lugqityiwe, ii-cuffs zoxinzelelo lwegazi ziyasuswa.

Musa ukutshaya ubuncinci imizuzu engama-30 ngaphambi kovavanyo. Uya kucelwa ukuba ususe yonke impahla engalweni nasemlenzeni kuvavanywa.

Akufanele ube nokungaphatheki kakuhle kolu vavanyo. Kuya kufuneka uve uxinzelelo lwekhofu yoxinzelelo lwegazi. Uvavanyo ludla ngokuthatha ngaphantsi kwemizuzu engama-20 ukuya kwengama-30 ukwenza.

Olu vavanyo luhlala lusenziwa ukukhangela ukunciphisa okanye ukuvaleka kwemithambo yegazi (imithambo) ezingalweni okanye emilenzeni.

Kufuneka kubekho ngaphantsi kwe-20 ukuya kwi-30 mm Hg umahluko kwi-systolic uxinzelelo lwegazi lomlenze xa kuthelekiswa naleyo yengalo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Isifo esiqhelekileyo sokuvela
• Amahlwili egazi
• Utshintsho lwesitya segazi ngenxa yeswekile
• Ukonzakala kwimithambo
• Esinye isifo semithambo yegazi (isifo semithambo)

Eminye imiqathango enokuthi yenzelwe uvavanyo:

• I-thrombosis enzulu yemithambo

Ukuba uneziphumo ezingaqhelekanga, unokufuna uvavanyo oluninzi ukuze ufumane eyona ndawo yokuncipha.

Akukho bungozi.

Olu vavanyo aluchanekanga njenge-arteriography. I-Plethysmography inokwenziwa kubantu abagula kakhulu abangakwaziyo ukuya kwilebhu ye-arteriography. Olu vavanyo lunokusetyenziselwa ukukhusela isifo se-vascular okanye ukulandela iimvavanyo ezingaqhelekanga zangaphambili.

Uvavanyo alunasive, kwaye alusebenzisi i-x-ray okanye inaliti yedayi. Ikwabiza kancinci kune-angiogram.
