How quickly can unconsciousness followed by death occur in suspended victims?

Unconsciousness followed by death in suspended victims can occur relatively quickly due to factors such as reduced blood flow to the brain and complications that arise from suspension. When a person is hanging or suspended, their blood circulation can be severely hampered, leading to a lack of oxygen to the brain. This can cause loss of consciousness in a matter of minutes.

The time frame of approximately 30 minutes aligns with studies and data regarding physiological responses to suspension and the critical thresholds for survival. The effects of gravity and the positioning of the body can cause venous pooling of blood and result in rapid hypoxia (lack of oxygen) to vital organs if the person remains suspended.

Therefore, the choice indicating that unconsciousness followed by death occurs around 30 minutes is accurate based on these physiological factors and the urgency required for rescue interventions in such scenarios.
