Baseline seated diastolic BP is the average of 3
consecutive seated diastolic bp value prior to or
equal to the drgdt and time, obtained atleast one
minute apart. If any of those 3 consecutive readings
are not within 10 mmhg of each other, then two
additional readings should be obtained to calculate
the average.

Thanks in advance for your help.
