TAKING YOUR BLOOD PRESSURE
4.
Before taking your blood pressure, you will need to set the
pressure switch to a number that is at least 30 mmHg higher
than your expected systolic pressure. Use the chart below as a
guide. For example, if you believe your blood pressure to be
140 (systolic) over 90 (diastolic), set the switch to 180. If you
know it is 120/80, you should set the switch to 150. Don't
worry if you set the pressure switch too low. The monitor will
automatically re-inflate to the next higher setting if it is unable
to detect the systolic pressure at the current setting.
NOTE: If your systolic reading is greater than 210, please press
and hold the "START" button until the pressure switch reaches
30 mmHg higher than your systolic reading. The maximum cuff
pressure is set at 320 mmHg. If it reaches 320 mmHg, the auto
exhaust will be triggered and cuff pressure will deflate to 0.
If you think you have set the pressure too high, stop the
inflation process by pressing START. Then reset the
switch to the next lower setting.
