I-Defibrillator: yintoni na, isebenza njani, ixabiso, i-voltage, i-manual nangaphandle

By UCristiano Antonino On Ngamana 19, 2022

I-Defibrillator ibhekisa kwisixhobo esithile esikwaziyo ukubona utshintsho kwisingqi sentliziyo kunye nokuhambisa ukothuka kombane entliziyweni xa kukho imfuneko: olu sothuko lunamandla okuphinda umise isingqisho se-'sinus', oko kukuthi isingqi sentliziyo esichanekileyo esilungelelaniswe yi-pacemaker yendalo yentliziyo, 'i-strial sinus node'

Ijongeka njani i-defibrillator?

Njengoko siza kubona kamva, kukho iindidi ezahlukahlukeneyo. Eyona 'yakudala', le siqhele ukuyibona kwiifilimu ngexesha likaxakeka, yi-manual defibrillator, ene-electrode ezimbini ekufuneka zibekwe esifubeni sesigulana (enye ukuya ngasekunene enye ngasekhohlo kwentliziyo. ) ngumsebenzisi kude kuhanjiswe ukukhutshwa.

Ziziphi iintlobo ze-defibrillators ezikhoyo?

Kukho iintlobo ezine ze-defibrillators

ngezandla
isemi-automatic yangaphandle
oluzenzekelayo lwangaphandle;
i-implantable okanye ngaphakathi.

I-defibrillator eyenziwe ngesandla

Uhlobo lwemanyuwali sesona sixhobo sinzima kakhulu sokusebenzisa njengoko naluphi na uvavanyo lweemeko zentliziyo lunikezelwe ngokupheleleyo kumsebenzisi walo, njengoko kuhlengahlengiswa kunye nokuguqulwa kokukhutshwa kombane ukuhanjiswa entliziyweni yesigulane.

Ngenxa yezi zizathu, olu hlobo lwe-defibrillator lusetyenziswa kuphela ngoogqirha okanye abaqeqeshi bezempilo abaqeqeshiweyo.

I-defibrillator yangaphandle ye-Semi-automatic

I-defibrillator yangaphandle ye-semi-automatic sisixhobo, ngokuchasene nohlobo lwencwadana, ekwazi ukusebenza ngokuzimeleyo ngokupheleleyo.

Emva kokuba i-electrodes idityaniswe ngokuchanekileyo kwisigulane, ngokusebenzisa i-electrocardiograms enye okanye ngaphezulu ukuba isixhobo sizenza ngokuzenzekelayo, i-defibrillator yangaphandle ye-semi-automatic iyakwazi ukumisela ukuba ngaba kuyimfuneko ukuhambisa ukutshitshiswa kombane entliziyweni: ukuba isigqi ngokwenene i-defibrillating, ilumkisa umqhubi wesidingo sokuhambisa umbane wombane kwi-heart muscle, ngenxa yokukhanya kunye / okanye iimpawu zezwi.

Ngeli xesha, umqhubi kufuneka acinezele kuphela iqhosha lokukhupha.

Eyona nto ibaluleke kakhulu kukuba kuphela ukuba isigulana sikwimeko yokubanjwa kwentliziyo iya kuthi i-defibrillator ilungiselele ukuhambisa umothuko: akukho nanye imeko, ngaphandle kokuba isixhobo asisebenzi kakuhle, kuya kwenzeka ukuba isigulana sibe nefibrillate, nokuba iqhosha lokungcangcazela. icinezelwe ngempazamo.

Olu hlobo lwe-defibrillator ngoko ke, ngokungafaniyo nohlobo lwencwadana, kulula ukuyisebenzisa kwaye lunokusetyenziswa nabasebenzi abangengabo bezonyango, nangona baqeqeshwe ngokufanelekileyo.

I-defibrillator ezenzekelayo ngokupheleleyo

I-defibrillator ngokuzenzekelayo (ihlala ifinyeziwe kwi-AED, ukusuka 'kwi-defibrillator yangaphandle ngokuzenzekelayo', okanye i-AED, 'i-defibrillator yangaphandle ngokuzenzekelayo') ilula ngakumbi kunohlobo oluzenzekelayo: lufuna kuphela ukuxhunywa kwisigulane kwaye lutshintshe.

Ngokungafaniyo ne-semi-automatic yangaphandle ye-defibrillators, xa imeko yokubanjwa kwentliziyo ibonakala, iqhubela phambili ngokuzimeleyo ukuhambisa umothuko entliziyweni yesigulane.

I-AED ingasetyenziselwa nabasebenzi abangengabo bezonyango abangenalo uqeqesho oluthile: nabani na unokuyisebenzisa ngokulula ngokulandela imiyalelo.

I-defibrillator yangaphakathi okanye efakelweyo

I-defibrillator yangaphakathi (ekwabizwa ngokuba yi-implantable defibrillator okanye i-ICD) yi-cardiac pacemaker eqhutywa yibhetri encinci kakhulu efakwe kufuphi ne-heart muscle, ngokuqhelekileyo phantsi kwe-collarbone.

Ukuba ibhalisa ukuphindaphinda okungaqhelekanga kokubetha kwentliziyo yesigulana, iyakwazi ukuzisa ngokuzimeleyo ukothuka kombane ukuzama ukubuyisela imeko kwimeko yesiqhelo.

I-ICD ayikho kuphela i-pacemaker ngokwayo (inamandla okulawula izingqisho ezicothayo zentliziyo, iyakwazi ukuqaphela i-heart arrhythmia kumazinga aphezulu kwaye iqalise unyango lombane ukuyisombulula ngaphambi kokuba ibe yingozi kwisigulane).

Kwakhona i-defibrillator yangempela: imo ye-ATP (i-Anti Tachy Pacing) ihlala ilawula ukuxazulula i-ventricular tachycardia ngaphandle kokuba isigulane sivakalelwe.

Kwiimeko eziyingozi kakhulu ze-ventricular arrhythmia, i-defibrillator ihambisa umothuko (ukukhutshwa kombane) obuyisela umsebenzi wentliziyo kwi-zero kwaye ivumela isigqi sendalo ukuba sibuyiselwe.

Kule meko, isigulane siziva sisothukile, i-jolt eyomelele ngakumbi okanye encinci embindini wesifuba okanye imvakalelo efanayo.

I-Defibrillators: i-voltages kunye nokukhupha amandla

I-defibrillator ngokubanzi inikwe amandla ngebhetri ehlaziywayo, nokuba yi-mains-powered okanye i-12-volt DC.

Ukunikezelwa kwamandla okusebenza ngaphakathi kwesixhobo luhlobo lwe-low-voltage, uhlobo oluthe ngqo.

Ngaphakathi, iintlobo ezimbini zeesekethe ziyakwazi ukwahlula: - i-low-voltage circuit ye-10-16 V, echaphazela yonke imisebenzi ye-ECG monitor, ibhodi iqulethe i-microprocessors, kunye nesekethe ezantsi kwe-capacitor; i-high-voltage circuit, echaphazela ukutshaja kunye nokukhupha isiphaluka se-defibrillation yamandla: oku kugcinwa yi-capacitor kwaye inokufikelela kwii-voltages ukuya kwi-5000 V.

Amandla okukhupha ngokuqhelekileyo yi-150, 200 okanye i-360 J.

Iingozi zokusebenzisa i-defibrillators

Ingozi yokutshisa: kwizigulane ezinobunwele obucacileyo, umaleko womoya wenziwa phakathi kwe-electrode kunye nesikhumba, okubangela ukudibana kombane okungalunganga.

Oku kubangela i-impedance ephezulu, kunciphisa ukusebenza kwe-defibrillation, kwandisa umngcipheko weentlantsi ezenza phakathi kwee-electrode okanye phakathi kwe-electrode kunye nolusu, kwaye kwandisa amathuba okubangela ukutshisa kwesifuba somguli.

Ukuze ugweme ukutshisa, kuyafuneka ukuba ugweme i-electrodes ethintana nomnye, i-bandages echukumisayo, i-transdermal patches, njl.

Xa usebenzisa i-defibrillator, umgaqo obalulekileyo kufuneka ugcinwe: akukho mntu uchukumisa isigulane ngexesha lokunikezelwa kokuthuthumela!

Umhlanguli kufuneka anyamekele ngokukhethekileyo ukuze aqinisekise ukuba akukho mntu uchukumisa isigulane, ngaloo ndlela ethintela umothuko ekufikeleleni kwabanye.
