How to log blood pressure

  1. Measure properlyRest five minutes, sit upright, cuff at heart level, and take two readings.
  2. Enter each readingAdd date, time, systolic, diastolic and pulse, then save.
  3. Review and shareCheck averages and categories, then export a CSV or copy the summary.

Blood pressure categories (AHA)

Blood pressure is written as systolic over diastolic in millimetres of mercury (mmHg). Systolic is the pressure when the heart beats, diastolic when it rests between beats.

Doctors judge blood pressure on averages of several readings over days or weeks, not on a single value. That is why this tracker focuses on 7 and 30-day averages.

Normal

Below 120 and below 80 mmHg.

Elevated / Stage 1

120-129 systolic, or 130-139 / 80-89.

Stage 2

140+ or 90+ mmHg; talk to your doctor.

Blood pressure log FAQ

What do the categories mean?

Following the American Heart Association: Normal is under 120/80; Elevated is 120-129 systolic with diastolic under 80; Stage 1 is 130-139 or 80-89; Stage 2 is 140 or higher or 90 or higher; above 180 and/or 120 is a hypertensive crisis.

Which number counts if they fall in different categories?

The higher category. For example 128/84 is Stage 1 because the diastolic is 80-89.

How should I measure at home?

Sit quietly for five minutes with your back supported, feet flat and arm at heart level. Take two readings a minute apart, morning and evening, and log both.

What is pulse pressure?

Systolic minus diastolic. A typical value is around 40 mmHg; consistently wide values are worth mentioning to your doctor.

Is this a medical diagnosis?

No. It is a personal log. A single high reading does not mean hypertension, and readings over 180/120 with symptoms need emergency care.
