Determining MAP Target in Shock

A 56-year-old male arrives at the emergency department after a severe car accident. He is found unresponsive with a Glasgow Coma Scale score of 6. Rapid assessment reveals an open fracture of the left femur and massive bleeding from the right thigh. The patient's heart rate is 130 beats per minute, blood pressure is 70/40 mmHg, and his respiratory rate is 32 breaths per minute.

As the charge nurse, you need to prioritize interventions for this patient. One key element in treating this patient in shock due to significant blood loss is the immediate administration of intravenous fluids. You need to calculate the rate of infusing a colloid solution at a target goal of achieving a minimum mean arterial pressure (MAP) of __________ mmHg to prevent organ failure.
