Frequently Asked Questions
What is a normal blood pressure reading?
According to American Heart Association categories, normal blood pressure is less than 120 systolic and less than 80 diastolic.
When is blood pressure considered high?
A reading enters hypertension ranges at 130 systolic or 80 diastolic. Stage 2 begins at 140 systolic or 90 diastolic, and readings above 180 systolic or 120 diastolic may be a hypertensive crisis.
Why should I log multiple blood pressure readings?
Blood pressure changes throughout the day. Tracking several readings helps you notice patterns and gives your doctor more useful information than a single measurement.
Does pulse affect blood pressure category?
No. Blood pressure categories are based on systolic and diastolic values. Pulse is still useful to record because it can give extra context about your cardiovascular state.
