Ambulatory blood pressure monitoring (ABPM) is a new method of evaluating the blood pressure of a person. Instead of sitting nervously on the doctor's examiner's table, ABPM allows the doctor to assess a patient’s blood pressure during their daily routine life. The Ambulatory Pressure Surveillance Blood (ABPM) is done to measure the blood pressure while individuals go around and live normal through everyday lives. It's small enough to prevent it from affecting your daily life and one can sleep with it.
ABPM, on the other hand, reports blood pressurizations one gets from
running to catching a bus to sleeping through a variety of activities and
situations. And during the many activities that someone normally performs in a
day, it is normal for blood pressure to fluctuate tremendously. Thus the ABPM
doesn't simply give a single value to the systolic or diastolic blood pressure,
unlike blood pressure in the doctor's office, it is supposed to represent your
official blood pressure, rather it reports a whole range of widely-variable
values (often over one day or longer).
A different approach to interpreting your blood pressure recordings is
required when using ABPM to diagnose hypertension. Average systolic and diastolic
blood pressures for a full 24 hour period and also for hours when the person
wakes up and goes to sleep are the most common technique used to assess the
results of ABPM.
Hypertension is diagnosed in general when one of the following values
exceeds the average blood pressure:
• Average 24-hour blood pressure: systemic blood pressure above 120
mmHg, or diastolic over 80 mmHg.
• The mean of "wake" times is systolic over 140 mmHg or
diastolic over 90 mmHg.
• Average time for "Asleep": systolic over 124 mmHg blood
pressure, or diastolic over 75 mmHg blood pressure.
When Is ABPM Used?
ABPM helps evaluate people with high blood pressure in a white coat,
enabling its doctors to determine if their in-office blood pressure levels
reflect a 'non-resting' state (i.e. anxiousness) rather than a 'quiet rest'
state required to accurately register blood pressure in-service. While the
frequent high blood pressure readings in the office show hypertension, this is
sometimes not the case.
