Which of the following is NOT a sign of immediate death according to the guidelines?

Severe internal bleeding, while a critical and life-threatening condition, is not an absolute indicator of immediate death according to medical guidelines. Individuals who experience severe internal bleeding may still retain vital signs and the potential for resuscitation, provided prompt medical intervention is administered.

On the other hand, obvious destruction of the heart, pulselessness accompanied by an apneic state, and rigor mortis with lividity are recognized as definitive signs of death. The destruction of the heart suggests that the organ can no longer function to support life. Pulselessness and apnea indicate a total lack of circulation and respiration, which are essential for sustaining life. Rigor mortis with lividity are post-mortem changes that occur in the body after death, further confirming that an individual has died. Understanding these distinctions is critical for assessing the clinical signs of death effectively.
