Tips for Accurate Readings

 

What to Avoid Before Measuring

 

Blood pressure changes from hour to hour — that's normal. What matters is the pattern. Measure at the same times each day, keep a simple log, and bring it to your next appointment. A week of readings in the same conditions is worth more than any single number.

 

When to talk to your doctor

A home monitor helps you track your blood pressure — it doesn't diagnose anything. If your readings stay consistently above the target your doctor set for you, rest for five minutes and measure again. If your reading is still high, call your local emergency number immediately — especially if you have chest pain, shortness of breath, weakness, or trouble seeing or speaking.
