Which principle of the HERT team indicates their readiness to respond to life-threatening situations?

The principle indicating the HERT team's readiness to respond to life-threatening situations is that they are ready to respond within 20 minutes with preassembled equipment. This emphasizes the importance of swift action in emergency situations where every second can make a critical difference in patient outcomes. The team's preparedness and the availability of necessary equipment ensure they can deploy quickly and effectively, which is vital for addressing urgent medical needs during crises.

Being prepared to act rapidly helps the HERT team minimize delays in care and supports effective intervention at the moment it is most needed. This immediate readiness contrasts with other principles, such as those related to long-distance transport or psychological support, which, while important, do not directly reflect the team's capability to act quickly in life-threatening scenarios.
