Doctors have placed humans in suspended animation for the first time

Emergency preservation and resuscitation (EPR) is trialled on patients whose hearts have stopped, and have lost more than half their blood due to acute trauma such as gunshot or stab wounds

Brain activity

almost stops

1

Surgeons have minutes to operate – there is less than 5% chance the patient would normally survive.

Person rapidly cooled

10-15C by replacing their blood with ice-cold saline

Heart stops beating

2

This gives surgeons more time to repair the wounds before reviving the patient

The person is warmed

back to 37C and

their heart restarted
