What is the normal range for mean arterial pressure (MAP)?

The normal range for mean arterial pressure (MAP) is typically considered to be between 70 and 110 mmHg. MAP is an important physiological measurement as it reflects the average blood pressure in a person's arteries during one cardiac cycle, and it is critical for ensuring adequate blood flow to the organs and tissues.

A MAP of 70 mmHg is generally regarded as the lower limit required to maintain proper perfusion pressure to vital organs, while values above 110 mmHg may indicate hypertension, which can have detrimental effects on cardiovascular health. Maintaining MAP within this range is essential in critical care to ensure that patients receive sufficient blood flow and therefore oxygen and nutrients to their organs. Thus, recognizing the normative value between 70 and 110 mmHg helps guide treatment strategies and interventions in managing patients effectively.
