M3 Vital Signs Monitor User Manual NIBP Monitoring (Optional)
- 64 -
WARNING
Prolonged non-invasive blood pressure measurements in automatic mode may be
associated with purpura, ischemic and neuropathy in the limb wearing the cuff. When
monitoring a patient, examine the extremities of the limb frequently for normal color,
warmth and sensitivity. If any abnormality is observed, stop the blood pressure
measurements.
NOTE:
1 The width of the cuff is either approximately 40% of the limb circumference or 2/3 of
the upper arm length. The inflatable part of the cuff should be long enough to encircle
80%-100% of the limb. The wrong size of cuff can cause erroneous readings. If the
cuff size is in question, use another cuff with suitable size to avoid errors.
2 If an NIBP measurement is suspect, repeat the measurement. If you are still
uncertain about the reading, use another method to measure the blood pressure.
3 Please make sure the cuff is well connected. A leak of air may cause measurement
error.
4 Please select the cuff with the suitable size. An unsuitable cuff may cause incorrect
measurements.
5 Avoid incursion of liquid into the cuff. If this happens, please desiccate the cuff
completely.
