Qhov Tseem Ceeb - Monophasic vs Biphasic Defibrillator
Qhov sib txawv tseem ceeb ntawm monophasic thiab biphasic defibrillator yog tias monophasic defibrillator yog ib hom defibrillation waveform qhov kev poob siab xa mus rau lub plawv los ntawm ib lub vector raws li qhia hauv qab no. Whereas, nyob rau hauv biphasic defibrillation, poob siab yog xa mus rau lub plawv ntawm ob vectors. Hauv lwm lo lus, kev poob siab monophasic tsuas yog muab rau hauv ib qho kev taw qhia ntawm ib qho hluav taws xob mus rau lwm qhov. Hauv kev poob siab biphasic, thawj qhov kev taw qhia ntawm kev poob siab yog thim rov qab los ntawm kev hloov cov polarity ntawm cov electrodes nyob rau tom kawg ntawm qhov kev poob siab raug xa.
Defibrillation yog dab tsi?
Defibrillation yog ib qho kev kho mob rau lub neej uas ua rau mob plawv dysrhythmias thiab ventricular fibrillation. Defibrillation muaj xws li xa cov tshuaj kho mob ntawm lub zog hluav taws xob mus rau lub plawv nrog lub cuab yeej hu ua defibrillator. Lub zog hauv lub defibrillator yog qhia hauv joules. Ib joule yog chav tsev ntawm kev ua haujlwm nrog rau ib lub amp ntawm tam sim no dhau los ntawm ib ohm ntawm kev tawm tsam rau ib pliag. Thaum peb nthuav qhia nws hauv ib qho qauv, nws feem ntau hais raws li hauv qab no:
Joules (Energy)=Voltage × Tam sim no × Time
Monophasic Defibrillator yog dab tsi?
Nyob rau hauv monophasic waveform, tsis muaj peev xwm hloov kho rau tus neeg mob impedance lossis kev tiv thaiv tam sim no los ntawm tus neeg mob lub cev, thiab nws feem ntau pom zoo kom tag nrho cov monophasic defibrillators xa 360J ntawm lub zog rau cov neeg laus kom ntseeg tau qhov siab tshaj plaws tam sim no. yog xa nyob rau hauv lub ntsej muag ntawm ib tug tsis muaj peev xwm mus ntes tus neeg mob impedance.
Biphasic Defibrillator yog dab tsi?
Biphasic waveforms tau pib tsim los siv rau hauv implantable defibrillators thiab tam sim no tau dhau los ua tus qauv hauv cov defibrillators sab nraud.
Implantable Defibrillator:
Cov no yog cov khoom siv cog me me hauv tus neeg mob lub cev uas tuaj yeem kuaj pom lub plawv dhia tsis zoo thiab txiav tawm los ntawm kev xa cov tam sim no hauv daim ntawv ntawm biphasic defibrillation.
External Defibrillator:
Cov defibrillators sab nraud yog cov khoom siv loj uas tuaj yeem xa ob lub zog defibrillation nyob rau hauv lub plawv dhia tsis zoo thaum tus neeg mob txuas nrog lub cuab yeej. Nov yog ib qho khoom siv tseem ceeb hauv chav xwm txheej ceev.
Biphasic waveforms tau pom tias tso cai txiav tawm ntawm ventricular fibrillation ntawm qis tam sim no dua li monophasic defibrillators.
Automated External Defibrillator (AED), nrog Paddles
Qhov txawv ntawm Monophasic thiab Biphasic Defibrillator yog dab tsi?
Muaj
Monophasic Defibrillator: Monophasic defibrillators tsis tshua nyiam nyob rau hauv cov ntsiab lus tam sim no.
Biphasic Defibrillator: Biphasic defibrillation muaj ntau niaj hnub no thiab siv rau implantable nrog rau sab nraud defibrillators.
Kho rau Tus Neeg Mob Impedance
Monophasic Defibrillator: Monophasic defibrillator tsis tuaj yeem kho qhov tam sim no raws li qhov kev tawm tsam los ntawm tus neeg mob lub cev.
Biphasic Defibrillator: Biphasic defibrillators muaj peev xwm hloov tau tam sim no raws li tus neeg mob lub impedance li no paub tias yuav ua tau zoo dua. Cov tuam txhab sib txawv tau siv cov haujlwm no los tsim ntau hom biphasic defibrillators.
Nyob rau tam sim no
Monophasic Defibrillator: Monophasic defibrillator siv lub zog tam sim no kom xa 360J lub zog los txiav tawm lub plawv arrhythmias.
Biphasic Defibrillator: Hauv qhov sib piv, biphasic defibrillators tuaj yeem hloov kho lub zog ntawm tam sim no, thiab nws siv zog tsawg dua li monophasic defibrillators.
Txhua yam ua tau zoo
Monophasic Defibrillator: Monophasic defibrillators tsawg dua.
Biphasic Defibrillator: Hauv qhov sib piv, biphasic defibrillators ua haujlwm tau zoo dua.
Risk of Damaging Heart Muscles
Monophasic Defibrillator: Monophasic defibrillator muaj kev pheej hmoo ntau dua ntawm kev puas tsuaj rau lub plawv cov leeg vim nws xa tawm ntau dua tam sim no.
Biphasic Defibrillator: Biphasic defibrillator siv qhov me me tam sim no thiab yog li qhov kev puas tsuaj tsawg kawg nkaus.
