I-Limb plethysmography

I-Limb plethysmography isivivinyo esiqhathanisa ukucindezelwa kwegazi emilenzeni nasezingalweni.

Lokhu kuhlolwa kungenziwa ehhovisi lomhlinzeki wezokunakekelwa kwempilo noma esibhedlela. Uzocelwa ukuba ulale nengxenye ephezulu yomzimba wakho iphakanyiswe kancane.

Izinduku ezintathu noma ezine zomfutho wegazi zisongwe kahle engalweni nasemlenzeni. Umhlinzeki ufaka izinkomishi, futhi umshini obizwa ngokuthi yi-plethysmograph ulinganisa ama-pulses avela kwikhafu ngayinye. Isivivinyo siqopha ingcindezi enkulu ekhishwa lapho izinkontileka zenhliziyo (systolic blood pressure).

Umehluko phakathi kwamapulse uyabonakala. Uma kukhona ukwehla kwenhliziyo phakathi kwengalo nomlenze, kungakhombisa ukuvinjelwa.

Lapho isivivinyo sesiphelile, izinkomishi zengcindezi yegazi ziyasuswa.

Ungabhemi okungenani imizuzu engama-30 ngaphambi kokuhlolwa. Uzocelwa ukuthi ususe zonke izingubo ezingalweni nasemlenzeni ovivinywayo.

Akufanele ube nokungaphatheki kahle ngalokhu kuhlolwa. Kufanele uzwe kuphela ingcindezi yesigaxa somfutho wegazi. Ukuhlolwa kuvame ukuthatha imizuzu engaphansi kwengu-20 kuya kwengu-30 ukwenza.

Lokhu kuhlolwa kuvame ukwenziwa ukuhlola ukuncipha noma ukuvinjelwa kwemithambo yegazi (emithanjeni) ezingalweni noma emilenzeni.

Kufanele kube khona umehluko ongaphansi kuka-20 kuye ku-30 ​​mm Hg kwi-systolic blood pressure yomlenze uma kuqhathaniswa naleyo yengalo.

Imiphumela engajwayelekile ingabangelwa:

• Isifo se-Arterial occlusive
• Amahlule egazi
• Umthambo wegazi uyashintsha ngenxa yesifo sikashukela
• Ukulimala emthanjeni
• Esinye isifo semithambo yegazi (isifo semithambo)

Ezinye izimo okungenziwa ukuhlolwa kuzo:

• I-thrombosis ejulile ye-venous

Uma unomphumela ongajwayelekile, kungadingeka ukuthi ube nokuhlolwa okwengeziwe ukuthola indawo eqondile yokuncipha.

Azikho izingozi.

Lokhu kuhlolwa akunembile njenge-arteriography. I-Plethysmography ingenziwa kubantu abagula kakhulu abangakwazi ukuya ebhodini le-arteriography. Lokhu kuhlolwa kungasetshenziselwa ukuhlola izifo ezinemithambo yegazi noma ukulandela izivivinyo ezingajwayelekile zangaphambilini.

Ukuhlolwa akuyona into engavumelekile, futhi ayisebenzisi ama-x-ray noma umjovo wedayi. Kubiza futhi kune-angiogram.
