defibrillator
Meaning: A device that delivers an electric shock to the heart to restore a normal rhythm during cardiac arrest or life-threatening arrhythmias.
Defibrillators are found in hospitals, ambulances, and increasingly in public places such as airports and shopping centres as automated external defibrillators (AEDs). An AED is designed to be used by untrained bystanders and provides voice-guided instructions. The verb form is 'defibrillate,' and the process is 'defibrillation.' Collocations include 'automated external defibrillator,' 'implantable defibrillator,' and 'deliver a shock.'

- The paramedics used a defibrillator to restore the patient's heart rhythm at the scene. 急救人员在现场使用除颤器恢复了患者的心律。Los paramédicos utilizaron un desfibrilador para restablecer el ritmo cardíaco del paciente en el lugar de los hechos.救急隊員は現場で除細動器を使い、患者の心拍リズムを回復させた。구급대원은 현장에서 제세동기를 사용하여 환자의 심장 리듬을 회복시켰다.
- Automated external defibrillators are now installed in most public buildings and can be operated by anyone. 如今大多数公共建筑都安装了自动体外除颤器,任何人都可以操作。Los desfibriladores externos automáticos están instalados ya en la mayoría de los edificios públicos y pueden ser manejados por cualquier persona.自動体外式除細動器は現在ほとんどの公共施設に設置されており、誰でも操作できる。자동 체외 제세동기(AED)는 현재 대부분의 공공건물에 설치되어 있으며, 누구나 조작할 수 있다.
- An implantable cardioverter-defibrillator continuously monitors the heart and delivers a shock if a dangerous arrhythmia is detected. 植入式心律转复除颤器持续监测心脏,一旦检测到危险的心律失常便自动放电。Un desfibrilador cardioversor implantable monitoriza continuamente el corazón y administra una descarga si detecta una arritmia peligrosa.植込み型除細動器は心臓を常時監視し、危険な不整脈が検出されると自動的に電気ショックを送る。이식형 제세동기는 심장을 지속적으로 모니터링하다가 위험한 부정맥이 감지되면 자동으로 전기 충격을 가한다.
