Note Be sure that the cuff is neither too tight nor too loose. When putting it on the
patient, wrap it so that you can comfortably fit two fingers between the cuff and
the arm.
Be sure that the air hose has no kinks or twists.
During an NIBP measurement, limit the movement of the cuff and the
cuffed extremity.
If the cuff is not level with the heart, add 1.8 mmHg to the displayed reading for
each inch of elevation above the heart, or subtract 1.8 mmHg from the displayed
reading for each inch of elevation below the heart.
Always use the appropriate cuff size for each patient.
