If Action 1 and Action 2 lead to Condition 1 and Condition 2, do the following to restore
the monitor to normal operation:
1. Power the monitor off.
2. Power the monitor on.
Start the blood-pressure measurement using the default target pressure.
Selecting a Cuff
You can tell whether the cuff size is appropriate by putting the cuff on the patient and then
inspecting the fit. If the edge marking lies somewhere between the two range markings,
then the fit is correct.
You can also find the correct cuff by measuring the circumference of the patient’s arm at
the biceps:
Positioning the Cuff
For the most accurate measurement, do the following:
1. Position the cuff on the bare arm, midway between the shoulder and the elbow.
Typical cuff positions are shown in this illustration:
2. Position the alignment mark on the cuff directly over the brachial artery.
