Lawyer: In a risky surgical procedure that is performed only with the patient' s informed consent, doctors intentionally cause the patient' s heart and brain functions to stop by drastically reducing the patient' s body temperature  When the procedure is completed, body temperature is quickly restored
Because the doctors deliberately stop the patient' s life functions, if these functions do not resume following the procedure, the medical team is technically guilty of manslaughter
Deliberately bringing about the cessation of a person's life functions is manslaughter if and only if the cessation is permanent.
