Resuscitation is emergency medical action used to restore breathing or circulation when a person has stopped breathing or their heart has failed. It includes techniques such as CPR, airway support, and automated defibrillation, all of which are time-critical and often performed under intense pressure. The goal is to keep oxygen moving to vital organs until normal function returns or advanced care takes over.
In cyber security, resuscitation matters because many emergency and hospital systems now depend on connected devices, software, and networked workflows. If ransomware, misconfiguration, or device failure slows access to monitors, alarms, or CPR equipment, the delay can directly affect patient survival. Defenders therefore focus on segmentation, backup power, manual override procedures, and staff training so lifesaving care can continue even when technology is unavailable or compromised.
