What’s in a BP: Do you FOLLOW THE MAP





MAP, aortic injury, AAA


The purpose of this case study is to help determine if emergency nursing education should include a focus on mean arterial pressure (MAP) and Pulse Pressure (PP) as part of their regular curriculum. We also considered if monitoring and trending BP, MAP and PP in patients who present with symptoms that may indicate a pulmonary and/or cardiac complaint, along with abnormal vital signs or abnormal lab values, would result in more timely intervention. Through this case study we hope to show that trending MAP may help identify early hypovolemic shock, severe sepsis   and other significant life threatening conditions.
