Home Blood Pressure Calculator

If you measure your own blood pressure at home, you can use this form to calculate the average of 10 readings, with an adjustment for home readings (we add 10 to the top number and 5 to the bottom number to give an equivalent to a surgery reading, as the targets for blood pressure have been based on surgery readings).

Press TAB to move from one box to the next, and press calculate once you have entered all 10 readings.
