Which of the following is most likely to result in life-threatening hemorrhage?

In order to maintain adequate perfusion to the vital organs of the body a mean arterial pressure (MAP) of 60 mmHg must be maintained. MAP is a calculation of average blood pressure using systolic and diastolic blood pressure measurements. MAP is calculated as follows:

A) MAP = DBP + (SBP–DBP)/3 B) MAP = SBP + (SBP–DBP)/2 C) MAP = DBP + (SBP–DBP)/2 D) MAP = SBP + (SBP–DBP)/3
