READING LOOKUP

Blood pressure 150 over 50 to 110

A top number of 150 is in the Stage 2 range on its own, so every 150 reading counts as Stage 2 whatever the bottom number.

150 over what? The quick answer

150/50 to 110: Stage 2 hypertension

Every 150 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 150 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.
