Calculating Mean Arterial Pressure (MAP) in a Patient

A nurse is assessing a 60-year-old patient who is experiencing signs of hypovolemic shock. The nurse notes that the patient's heart rate is elevated at 110 beats per minute and blood pressure is low at 85/50 mmHg. To calculate the patient's mean arterial pressure (MAP), which is an important indicator of hemodynamic status, the nurse must apply the following formula:

MAP = DBP + (1/3 x (SBP - DBP))

Using the patient's blood pressure readings, fill in the blank below to determine the patient's MAP:

MAP = ______ mmHg
