Blood Pressure Q & A
Q: What is the difference between measuring blood pressure at home or at a pro-
fessional healthcare clinic?
A: Blood pressure readings taken at home are now seen to give a more accurate
account as they better reflect your daily life. Readings can be elevated when taken
in a clinical or medical environment. This is known as White Coat Hypertension and
may be caused by feeling anxious or nervous.
Note: Abnormal test results may be caused by:
1. Improper cuff placement
Make sure cuff is snug-not too tight or too loose.
Make sure bottom of the cuff is approximately 1-2cm (1/2’’) above the elbow joint.
2. Improper body position
Make sure to keep your body in an upright position.
3. Feeling anxious or nervous
Take 2-3 deep breaths, wait a few minutes and resume testing.
Q: What causes different readings?
A: Blood pressure varies throughout the course of a day. Many factors including
diet, stress, cuff placement, etc. may affect an individual’s blood pressure.
Q: Should I apply the cuff to the left or right arm? What is the difference?
A: Either arm can be used when testing, however, when comparing results, the
same arm should be used. Testing on your left arm may provide more accurate re-
sults as it is located closer to your heart.
Q: What is the best time of day for testing?
A: Morning time or any time you feel relaxed and stress free.
