Erroneous NIBP measurement
 Check for proper cuff size
1. Too small a cuff can give an erroneously high value.
2. Too large a cuff can give an erroneously low value.
 Check for residual air left in the cuff from a previous measurement.
 Make sure cuff is not too tight or too loose.
 Make sure cuff and heart are at same level, otherwise hydrostatic pressure will offset the
NIBP value.
 Minimize patient movement during measurement.
 Check for leak in cuff or tubing.
 Patient may have a weak pulse.
