ABOUT BLOOD PRESSURE
ANSWERS TO WHY YOUR READINGS ARE DIFFERENT BETWEEN HOME AND
AT THE DOCTOR’S OFFICE
Why are my readings different between home and at a doctor’s office?
Your blood pressure readings taken in a doctor’s office or hospital setting may be
elevated as a result of apprehension and anxiety. This response is known as white
coat hypertension.
When I bring my monitor to a doctor’s office, why do I get a different
measurement from my monitor to that taken by a doctor or nurse?
The healthcare professional may be using a different sized cuff. The size of the
bladder inside the cuff is critical for the accuracy of the measurement. This may
give you a different reading. A cuff too large will produce a reading that is lower
than the correct blood pressure; a cuff that is too small will produce a reading that
is higher than the correct blood pressure. There may also be other factors that can
cause the difference in measurements.
KEYS TO SUCCESSFUL MONITORING:
Blood pressure fluctuates throughout the day. We recommend that you are
consistent in your daily measurement routine:
• Measure at the same time every day.
• Sit in the same chair/position.
• Do not cross legs and keep your feet flat on the floor.
• Relax for several minutes before measurement.
• Use the correct cuff size to get an accurate reading.
• Sit still during measurement – no talking, eating or sudden movements.
• Record your measurement in a logbook.
