Doctors successfully suspend human in animation

The video discusses a trial involving suspended animation to save gunshot or stabbing victims. Maryland University researcher Samuel Tischerman explains that traumatic injuries can lead to massive blood loss and cardiac arrest, causing brain damage within 5 minutes. The emergency preservation and resuscitation (EPR) technique replaces the patient's blood with ice-cold saline, reducing oxygen needs and allowing surgeons two hours to operate. The trial compares EPR results on 10 patients with a control group at the university hospital.

What is the significance of cooling the body and brain during the EPR procedure?

How many patients are involved in the trial comparing EPR's results?
