Which is true about biological death?

Biological death refers to a state in which irreversible cellular damage has occurred, signaling that the body's cells and systems can no longer sustain life. This state is marked by significant changes at the cellular and systemic levels, including loss of function in vital organs, especially the brain. Once biological death occurs, recovery is not possible, making it distinct from clinical death, which may still allow for resuscitative efforts, such as CPR, to restore functions if performed quickly.

The key idea is that biological death signifies a point of no return, with damage to cells and tissues that cannot be reversed, thus differentiating it from reversible states where interventions might still lead to recovery. Understanding this distinction is important in emergency response scenarios as it affects decision-making regarding resuscitation and the application of available medical interventions.
