What does my blood pressure reading mean?

Type in the two numbers from your monitor and get a personal report: your US category, the body metrics behind it, a plan to reach target and a 7-day home log.

What your numbers measure

Systolic · upper number

The peak pressure each time your heart contracts. It rises as arteries stiffen with age and is the stronger predictor of stroke and heart attack after about 50.

Diastolic · lower number

The pressure that remains while the heart refills. A raised diastolic value is more typical of younger adults and often the first number to climb.

Mean & pulse pressure

Every reading report also shows the mean arterial pressure (what your organs "feel") and the gap between the numbers, a window into artery elasticity.

Every reading report includes a personal "path to target" planner and a printable 7-day home log. Start with blood pressure explained.
