I-Defibrillator: iyini, isebenza kanjani, intengo, i-voltage, imanuwali neyangaphandle

By UCristiano Antonino On Kwangathi 19, 2022

I-Defibrillator isho ithuluzi elithile elikwazi ukubona izinguquko esigqini senhliziyo futhi lilethe ukushaqeka kukagesi enhliziyweni lapho kudingekile: lokhu kushaqeka kunamandla okuvuselela isigqi 'se-sinus', okungukuthi isigqi senhliziyo esifanele esixhunyaniswa ne-pacemaker yemvelo yenhliziyo, 'i-strial sinus node'

Ibukeka kanjani i-defibrillator?

Njengoba sizobona kamuva, kunezinhlobo ezihlukahlukene. Eyakudala kakhulu, le esijwayele ukuyibona emafilimini ngesikhathi sezimo eziphuthumayo, i-defibrillator manual, equkethe ama-electrode amabili okumelwe abekwe esifubeni sesiguli (enye kwesokudla nesinye kwesokunxele senhliziyo. ) ngo-opharetha kuze kukhishwe ukukhishwa.

Yiziphi izinhlobo ze-defibrillator ezikhona?

Kunezinhlobo ezine zama-defibrillator

inhlukano
i-semi-automatic yangaphandle
okuzenzakalelayo kwangaphandle;
okufakelwayo noma kwangaphakathi.

I-defibrillator eyenziwe ngesandla

Uhlobo lwemanyuwali luyithuluzi eliyinkimbinkimbi kakhulu elingase lisetshenziswe njengoba noma yikuphi ukuhlolwa kwezimo zenhliziyo kunikezwa ngokuphelele kumsebenzisi walo, njengoba kunjalo nokulinganisa nokuguquguquka kokukhishwa kukagesi okuzolethwa enhliziyweni yesiguli.

Ngenxa yalezi zizathu, lolu hlobo lwe-defibrillator lusetshenziswa kuphela odokotela noma ochwepheshe bezempilo abaqeqeshiwe.

I-Semi-automatic defibrillator yangaphandle

I-defibrillator yangaphandle ye-semi-automatic iyisisetshenziswa, ngokuphambene nohlobo lwebhukwana, olukwazi ukusebenza cishe ngokuzenzakalelayo ngokuphelele.

Uma ama-electrode exhunywe ngendlela efanele esigulini, ngokusebenzisa i-electrocardiogram eyodwa noma ngaphezulu idivayisi eyenza ngokuzenzakalelayo, i-semi-automatic yangaphandle i-defibrillator iyakwazi ukuthola ukuthi kudingekile yini ukuletha ukushaqeka kukagesi enhliziyweni: uma isigqi empeleni si-defibrillating, sixwayisa opharetha ngesidingo sokuletha ukushaqeka kukagesi kumisipha yenhliziyo, ngenxa yokukhanya kanye/noma izimpawu zezwi.

Kuleli qophelo, opharetha kufanele acindezele inkinobho yokukhipha kuphela.

Isici esibaluleke kakhulu ukuthi kuphela uma isiguli sisesimweni sokuboshwa kwenhliziyo lapho i-defibrillator izozilungiselela ukuletha ukushaqeka: akukho okunye, ngaphandle uma idivayisi ingasebenzi kahle, ingabe isiguli sizokwazi ukwenza i-fibrillate, ngisho noma inkinobho yokushaqeka. icindezelwa ngephutha.

Lolu hlobo lwe-defibrillator ngakho-ke, ngokungafani nohlobo lwemanyuwali, kulula ukuyisebenzisa futhi lungasetshenziswa nabasebenzi abangezona ezokwelashwa, nakuba baqeqeshwe ngokufanele.

I-defibrillator ezenzakalelayo ngokugcwele

I-automated defibrillator (evame ukufushaniswa ku-AED, kusukela ku-'automated external defibrillator', noma i-AED, 'i-defibrillator yangaphandle ezenzakalelayo') ilula nakakhulu kunohlobo oluzenzakalelayo: idinga kuphela ukuxhunywa esigulini futhi ivulwe.

Ngokungafani nama-semi-automatic external defibrillator, uma isimo sokuboshwa kwenhliziyo sesibonwa, aqhubeka ngokuzimele ukuletha ukushaqeka enhliziyweni yesiguli.

I-AED ingasetshenziswa nayizisebenzi ezingezona ezezokwelapha ezingenakho ukuqeqeshwa okuqondile: noma ubani angayisebenzisa ngokulandela imiyalelo nje.

I-defibrillator yangaphakathi noma efakelwayo

I-defibrillator yangaphakathi (ebuye ibizwe ngokuthi i-implantable defibrillator noma i-ICD) iyi-pacemaker yenhliziyo enikwa amandla ibhethri elincane kakhulu elifakwe eduze kwemisipha yenhliziyo, ngokuvamile ngaphansi kwe-collarbone.

Uma ibhalisa imvamisa engavamile yokushaya kwenhliziyo yesiguli, iyakwazi ukuletha ngokuzimele ukushaqeka kukagesi ukuze izame ukubuyisela isimo kwesijwayelekile.

I-ICD ayiyona nje i-pacemaker ngokwayo (inamandla okulawula isigqi senhliziyo esinensayo, ingakwazi ukubona ukungezwani kwenhliziyo ngamanani aphezulu futhi iqale ukwelashwa ngogesi ukuyixazulula ngaphambi kokuba ibe yingozi esigulini).

Kubuye kube i-defibrillator yangempela: imodi ye-ATP (Anti Tachy Pacing) ngokuvamile ikwazi ukuxazulula i-tachycardia ye-ventricular ngaphandle kokuba isiguli siyizwe.

Ezimweni eziyingozi kakhulu ze-ventricular arrhythmia, i-defibrillator iletha ukushaqeka (ukukhishwa kukagesi) okusetha kabusha ukusebenza kwenhliziyo ku-zero futhi ivumele isigqi semvelo ukuthi sibuyiselwe.

Kulesi simo, isiguli sizwa ukushaqeka, i-jolt enamandla kakhulu noma engaphansi phakathi kwesifuba noma ukuzwa okufanayo.

Ama-Defibrillators: ama-voltage namandla okukhipha

I-defibrillator ngokuvamile inikwa amandla ibhethri elishajekayo, elinamandla amakhulu noma i-12-volt DC.

Ukunikezwa kwamandla okusebenza ngaphakathi kwedivayisi kungokwe-low-voltage, uhlobo lwamanje oluqondile.

Ngaphakathi, izinhlobo ezimbili zamasekhethi zingahlukaniswa: - isekethe ye-low-voltage engu-10-16 V, ethinta yonke imisebenzi yokuqapha kwe-ECG, ibhodi equkethe ama-microprocessors, kanye nesifunda esingezansi kwe-capacitor; umjikelezo we-high-voltage, othinta ukushaja nokukhipha isekethe yamandla we-defibrillation: lokhu kugcinwa yi-capacitor futhi kungafinyelela ku-voltages afika ku-5000 V.

Amandla okukhipha ngokuvamile angu-150, 200 noma 360 J.

Izingozi zokusebenzisa ama-defibrillators

Ingozi yokusha: ezigulini ezinezinwele ezigqamile, ungqimba lomoya lwenziwa phakathi kwama-electrode nesikhumba, okubangela ukuthintana kahle kukagesi.

Lokhu kubangela ukuphazamiseka okukhulu, kunciphisa ukusebenza kahle kwe-defibrillation, kwandisa ingozi yokuvela kwezinhlansi phakathi kwama-electrode noma phakathi kwe-electrode nesikhumba, futhi kwandisa amathuba okuba kubangele ukusha esifubeni sesiguli.

Ukuze ugweme ukushisa, kuyadingeka futhi ukugwema ama-electrode ukuthintana, ukuthinta amabhandeshi, ama-patches transdermal, njll.

Uma usebenzisa i-defibrillator, kufanele kuqashelwe umthetho obalulekile: akekho othinta isiguli ngesikhathi sokulethwa kokushaqeka!

Umhlengi kufanele anakekele ngokukhethekile ukuze aqinisekise ukuthi akekho othinta isiguli, ngaleyo ndlela avimbele ukushaqeka ekufinyeleleni kwabanye.
