Calculating MAP in Severe Sepsis

A nurse is caring for a patient in the intensive care unit (ICU) who is experiencing severe sepsis. The patient has a heart rate of 120 beats per minute, a blood pressure of 80/50 mmHg, and decreased urine output. The nurse understands that in severe sepsis, maintaining perfusion is critical. The nurse needs to calculate the patient's mean arterial pressure (MAP) to assess hemodynamic stability. The formula for MAP is:

MAP = DBP + (SBP - DBP) / 3

Using the patient's blood pressure of 80/50 mmHg, the blank must be filled in with the calculated MAP value to determine if the hemodynamics are adequate for this patient.
