Every 145 reading

Pulse pressure is the top number minus the bottom number. MAP (mean arterial pressure) is the bottom number plus a third of the pulse pressure.

What to do with a 145 reading

Sit quietly for 5 minutes and take two readings a minute apart. If home readings average in this range over a week, share them with your doctor, who will look at them alongside your overall heart risk.

Readings move from minute to minute, and the first one usually runs a few points higher. The home measuring guide covers how to get a reading you can trust, and the 7-day home average turns a week of readings into the number your doctor uses. To check any reading, use the category checker.
