Defibrillator: chomwe chiri, momwe chimagwirira ntchito, mtengo, magetsi, buku ndi kunja
Defibrillator imatanthawuza chida china chomwe chimatha kuzindikira kusintha kwa kamvekedwe ka mtima ndikupereka kugunda kwamagetsi pamtima pakafunika kutero: kugwedezeka kumeneku kumatha kuyambitsanso kamvekedwe ka 'sinus', mwachitsanzo, kamvekedwe koyenera ka mtima kogwirizana ndi pacemaker yachilengedwe ya mtima, 'strial sinus node'
Kodi defibrillator imawoneka bwanji?
Monga momwe tidzaonera m’tsogolomu, pali mitundu yosiyanasiyana. 'Yachikale' kwambiri, yomwe timazolowera kuwonera m'mafilimu panthawi yadzidzidzi, ndiyo defibrillator yopangidwa ndi manja, yomwe imakhala ndi maelekitirodi awiri omwe ayenera kuikidwa pachifuwa cha wodwalayo (imodzi kumanja ndi ina kumanzere kwa mtima. ) ndi wogwiritsa ntchito mpaka atatulutsidwa.

Ndi mitundu yanji ya defibrillator yomwe ilipo?
Pali mitundu inayi ya defibrillators
- Buku
- kunja theka-zodziwikiratu
- zodziwikiratu zakunja;
- woyika kapena wamkati.
Manual defibrillator
Mtundu wa bukhuli ndi chipangizo chovuta kwambiri chogwiritsira ntchito popeza kuwunika kulikonse kwa mtima wamtima kumaperekedwa kwa wogwiritsa ntchito, monga momwe amachitira ndi kusinthasintha kwa kutuluka kwa magetsi kuti aperekedwe ku mtima wa wodwalayo.
Pazifukwa izi, mtundu uwu wa defibrillator umangogwiritsidwa ntchito ndi madokotala kapena akatswiri odziwa zachipatala.
Semi-automatic kunja defibrillator
The semi-automatic kunja defibrillator ndi chipangizo, mosiyana ndi buku lamanja, lomwe limatha kugwira ntchito pafupifupi palokha.
Ma electrode akalumikizidwa molondola ndi wodwalayo, pogwiritsa ntchito electrocardiograms imodzi kapena zingapo zomwe chipangizocho chimadzipangira chokha, semi-automatic external defibrillator amatha kudziwa ngati kuli kofunikira kuti apereke kugunda kwamagetsi pamtima: ngati rhythm kwenikweni ndi defibrillating, imachenjeza woyendetsa kufunikira kopereka mphamvu yamagetsi ku minofu ya mtima, chifukwa cha kuwala ndi / kapena zizindikiro za mawu.
Pakadali pano, wogwiritsa ntchitoyo amangodina batani lotulutsa.
Chinthu chofunika kwambiri ndi chakuti pokhapokha ngati wodwala ali ndi vuto la kugwidwa kwa mtima, wothandizira angakonzekere kuti apereke mantha: palibe vuto lina lililonse, pokhapokha ngati chipangizocho chitasokonekera, kodi zingatheke kusokoneza mtima wa wodwalayo, ngakhale batani logwedeza. amapanikizidwa molakwitsa.
Mtundu woterewu wa defibrillator ndiye, mosiyana ndi buku lamanja, losavuta kugwiritsa ntchito komanso lingagwiritsidwe ntchito ndi anthu omwe siachipatala, ngakhale ophunzitsidwa bwino.
Defibrillator kwathunthu
The automated external defibrillator (nthawi zambiri amafupikitsidwa ku AED, kuchokera ku 'automated external defibrillator', kapena AED, 'automated external defibrillator') ndi yosavuta kusiyana ndi mtundu wodziwikiratu: imangofunika kulumikizidwa kwa wodwalayo ndi kuyatsa.
Mosiyana ndi ma semi-automatic external defibrillators, akangozindikira kuti mtima wagwidwa, amapita patsogolo kuti apereke kugwedezeka kwa mtima wa wodwalayo.
AED ingagwiritsidwenso ntchito ndi anthu omwe siachipatala omwe alibe maphunziro apadera: aliyense angagwiritse ntchito potsatira malangizo.
Internal kapena implantable defibrillator
Defibrillator yamkati (yomwe imatchedwanso implantable defibrillator kapena ICD) ndi pacemaker ya mtima yomwe imayendetsedwa ndi batri yaing'ono kwambiri yomwe imayikidwa pafupi ndi minofu ya mtima, kawirikawiri pansi pa collarbone.
Ikazindikira kugunda kwamtima kwa wodwala, imatha kubweretsa kugunda kwamagetsi palokha kuti izi zibwerere mwakale.
ICD sikuti ndi pacemaker yokhayokha (imakhala ndi mphamvu yoyendetsa kayendedwe ka mtima pang'onopang'ono, imatha kuzindikira mtima wa arrhythmia pamtengo wapamwamba ndikuyambitsa chithandizo chamagetsi kuti athetse vutoli lisanakhale loopsa kwa wodwalayo).
Komanso ndi defibrillator yeniyeni: njira ya ATP (Anti Tachy Pacing) nthawi zambiri imatha kuthetsa tachycardia ya ventricular popanda wodwalayo kumva.
Muzochitika zowopsa kwambiri za ventricular arrhythmia, defibrillator imapereka kugwedezeka (kutulutsa kwamagetsi) komwe kumapangitsanso ntchito ya mtima ku zero ndikulola kuti nyimbo yachilengedwe ibwezeretsedwe.
Pankhaniyi, wodwalayo amamva kugwedezeka, kugwedezeka kwamphamvu kwambiri pakati pa chifuwa kapena kumverera kofanana.
Ma defibrillators: ma voltages ndi mphamvu zotulutsa
Defibrillator nthawi zambiri imayendetsedwa ndi batire yowonjezedwanso, yokhala ndi mains-powered kapena 12-volt DC.
Mphamvu yogwiritsira ntchito mkati mwa chipangizocho ndi yamagetsi otsika, amtundu wamakono.
Mkati, mitundu iwiri ya mabwalo imatha kusiyanitsa: - gawo laling'ono la 10-16 V, lomwe limakhudza ntchito zonse za polojekiti ya ECG, bolodi okhala ndi ma microprocessors, ndi dera kumunsi kwa capacitor; wozungulira wothamanga kwambiri, womwe umakhudza kuthamangitsa ndi kutulutsa mphamvu ya defibrillation: izi zimasungidwa ndi capacitor ndipo zimatha kufikira ma voltages mpaka 5000 V.
Mphamvu yotulutsa nthawi zambiri imakhala 150, 200 kapena 360 J.
Zowopsa zogwiritsa ntchito ma defibrillators
Kuopsa kwa kutentha: kwa odwala omwe ali ndi tsitsi lodziwika bwino, mpweya umapangidwa pakati pa maelekitirodi ndi khungu, zomwe zimapangitsa kuti magetsi asagwirizane.
Izi zimabweretsa kutsekeka kwakukulu, kumachepetsa mphamvu ya defibrillation, kumawonjezera ngozi yoti moto upangike pakati pa maelekitirodi kapena pakati pa ma elekitirodi ndi khungu, ndikuwonjezera mwayi woyambitsa kutentha pachifuwa cha wodwalayo.
Kuti mupewe kuyaka, ndikofunikira kupewa ma electrode kukhudzana wina ndi mnzake, kukhudza mabandeji, zigamba za transdermal, ndi zina zambiri.
Mukamagwiritsa ntchito defibrillator, lamulo lofunikira liyenera kuwonedwa: palibe amene amakhudza wodwala panthawi yobereka modzidzimutsa!
Wopulumutsayo ayenera kusamala kwambiri kuti atsimikizire kuti palibe amene akukhudza wodwalayo, motero kulepheretsa kugwedezekako kufika kwa ena.
