Taking a Measurement (cont.)

5. Squeeze the bulb to inflate the cuff until the needle on

the dial is 30-40 mmHg above your normal blood pressure.

If you can still hear the sound of your blood flow through

the stethoscope, pump up the cuff to 200 mmHg.

6. Slightly turn the valve counter-clockwise to slowly deflate

the cuff. Aim for a deflation rate of 2-3 mmHg per second.

Deflation over a 3 second span

NOTE:

We've colored a portion

of the dial to mark the

healthy range, so you

can quickly interpret

your results.

7. While the cuff is deflating, carefully listen with your

stethoscope. When you hear the first "thump" of blood

flow resuming, write down the number indicated on the

dial as your systolic number. These sounds will become

more muted as the cuff pressure drops—when you hear

the last "thump", mark down the number on the dial as

the diastolic pressure. The needle on the dial will "jump"

whenever you hear blood flow.
