It’s called the mean arterial pressure (MAP).” The American Heart Association (AHA) considers a systolic pressure below 120 and a diastolic pressure below 80 to be normal for adults.

Systolic and diastolic BP are the pressures at the highest and lowest points, respectively, of the arterial waveform. Mean arterial pressure is ... accurately obtained normal BP does not equate ...

Blood volume is markedly reduced, which produces a lower end-diastolic pressure. The purpose of this paper is to review the normal arterial pressure waveform, contrast the differences in waveform ...
