What is the mean arterial pressure? The mean arterial pressure (MAP) is defined as an approximation of a time-weighted average of blood pressure values in large system arteries during the cardiac cycle. It is directly related to the cardiac output. To calculate the MAP, you need two values - you systolic and diastolic blood pressure.
Periods of anxiety trigger the release of hormones that cause increased heart rate and decreased blood vessel diameter, both of which lead to increased blood pressure. 1  The effect of stress on short term blood pressure can be dramatic, leading to mean arterial pressure increases of 30%-40%. These changes are short lived, though, with heart rate, blood vessel diameter, and blood pressure returning to normal as the hormones are eliminated.
