Soj ntsuam kev siv tshuaj ntawm defibrillator
1 ntaus ntawv
Qhov hluav taws xob cardioversion tshuab, tseem hu ua defibrillator, yog cov khoom tseem ceeb rau kev siv hluav taws xob cardioversion. Nruab nrog electrode daim hlau, feem ntau ntawm lawv muaj ob khub ntawm loj thiab me me. Qhov loj yog haum rau cov laus thiab tus me yog haum rau cov menyuam yaus. Ua ntej siv, xyuas seb lub defibrillator lub zog puas ruaj khov, seb lub hwj huam hluav taws xob puas yog qhov yuam kev, seb lub tsub hluav taws xob muaj roj txaus, thiab seb puas muaj cov xaim hluav taws xob tau tawg thiab yog tias kev sib tiv tauj tsis zoo, tus tiv thaiv, raws li cov khoom siv cawm, yuav tsum saib xyuas kom zoo kev ua haujlwm, thiab lub roj teeb yuav tsum tau them tag nrho, yog li kev hloov hluav taws xob thaum muaj xwm ceev tuaj yeem siv tau txhua lub sijhawm thaum muaj xwm txheej ceev.
2 Lub tshuab hluav taws xob
Muaj ob txoj haujlwm ntawm cov paib electrode nyob rau sab nraud cardioversion. Ib qho yog hu ua anteroposterior txoj hauj lwm, uas yog, ib lub phaj electrode tau muab tso rau hauv cheeb tsam subscapular ntawm nraub qaum; lwm qhov tau muab tso rau theem ntawm 3-4 intercostal qhov chaw nyob rau sab laug ntug ntawm sternum. Qee tus neeg ntseeg hais tias hom no kis tau tam sim no ntau los ntawm lub siab, yog li qhov hluav taws xob tsawg yuav tsum muaj, thiab muaj peev xwm ua teeb meem tuaj yeem txo qis. Xaiv hluav taws xob cardioversion yuav tsum siv hom no. Lwm qhov yog daim phiaj electrode tso rau hauv 2 ~ 3 intercostal qhov chaw (hauv qab lub plawv) ntawm txoj cai ntug ntawm pob tw. Lwm qhov yog muab tso rau hauv qhov thib tsib intercostal qhov chaw (apex ntawm lub siab) nyob rau hauv sab laug anterior axillary kab. Txoj kev no yog sai thiab yooj yim, thiab tsim nyog rau kev kho hluav taws xob thaum muaj xwm ceev los tiv thaiv kev kub ntxhov. Qhov kev ncua deb ntawm ob daim hlau electrode yuav tsum tsis pub tsawg dua l0cm. Daim phaj electrode yuav tsum nyob ze rau tus neeg mob' s ntawm daim tawv nqaij thiab maj mam nias, tsis muaj qhov khoob, yuav tsum tsis muaj qhov khoob, thiab cov npoo yuav tsum tsis txhob nqa. Cov tawv nqaij uas cov electrodes tso rau yuav tsum tau coated nrog conductive paste, saline gauze tseem tuaj yeem siv, lossis tseem siv dej tuaj yeem siv thaum muaj xwm txheej ceev, tab sis dej cawv yog txwv tsis pub, txwv tsis pub nws yuav ua rau tawv nqaij kub. Cov neeg uas nyias nyias thiab qhov chaw sib tshuam ua haujlwm yog pom tseeb tshav ntuj thiab cov electrode nyob rau hauv kev sib cuag tsis zoo nrog rau daim tawv nqaij yuav tsum siv cov tshuaj tiv thaiv saline, thiab ob peb txheej ntxiv tuaj yeem siv los txhim kho kev sib cuag ntawm daim tawv nqaij thiab cov electrode. Khaws kom qhuav ntawm ob daim hlau hluav taws xob kom tsis txhob luv luv Circuit Court los ntawm kev muab tshuaj txhuam los yog ntsev txuas. Qhov kov ntawm cov ntawv electrode tseem yuav tsum tau ceev kom qhuav. Nws yuav tsum tsis txhob kis los ntawm kev coj ua los yog ntsev dej kom tsis txhob raug mob rau tus neeg teb xov tooj. Thaum lub plawv phais lossis qhib lub plawv zaws yuav tsum siv hluav taws xob ncaj qha kev tiv thaiv lub plawv, yuav tsum tau tshwj xeeb cov phaj hluav taws xob tshwj xeeb, ib qho tso rau saum npoo ntawm txoj cai ventricle; lwm qhov yog tso rau ntawm apex ntawm lub plawv, lub ntsej muag hauv lub siab yog xaum nrog dej qab ntsev, thiab lub khob electrode ze rau ntawm phab ntsa ventricular.
3 xaiv ntawm lub zog hluav taws xob
Lub zog hluav taws xob siv hauv hluav taws xob cardioversion yog sawv cev los ntawm J. Them raws li kev xav tau, ventricular fibrillation yog 250J ~ 300J, asynchronous cardioversion. Ventricular tachycardia yog 150J ~ 200J, atrial fibrillation yog 150J ~ 200J, atrial flutter yog 80J ~ 100J, thiab tachycardia supraventricular yog 100J, tag nrho cov uas muaj synchronous cardioversion.
