IPA: /rɪˈsʌsɪteɪtə/
KK: /rɪˈsʌsɪteɪtər/
A device or person that helps to bring someone back to life or restore their breathing after they have stopped breathing.
The paramedics used a resuscitator to help the patient breathe again after the accident.
Resuscitator → It is formed from "re-" (meaning again) and "suscitare" (meaning to raise or revive). The word "resuscitator" refers to a person or device that brings someone back to life or consciousness again.
Think of someone who 'raises' ('suscitare') someone 'again' ('re-') — that's why a resuscitator is someone or something that helps bring a person back to life.
