NBP
Problem:
Why are my NBP readings inaccurate?
Answer:
The monitor is unable to detect adequate pulsations or is
detecting excessive movement.
Intervention:
■ Check for proper cuff size. Make sure the cuff is not
too loose or too tight:
• A cuff that is too small will give an erroneously
high value.
• A cuff that is too large, will give an erroneously
low value.
■ Check for residual air left in the cuff from the
previous measurement.
■ Make sure the cuff and heart are at the same level,
otherwise hydrostatic pressure will offset the NBP
value.
■ Minimize patient movement during assessment.
■ Watch for pulsus paradoxes.
■ Check for a leak in the cuff or tubing.
■ Patient may have a weak pulse.
■ Calibration may be necessary.
■ Confirm Blood Pressure utilizing the ausculatory
method.
Problem:
Why do the MAP readings for the calculated not match
the NBP MAP from the monitor reading?
Answer:
The formula used to calculate assumes the ausculative
measurement was used to determine the SBP and DBP.
These numbers are used to calculate a MAP. When
utilizing the oscillometric method in the monitor, the
MAP is determined and the SBP and DBP are then
calculated.
Intervention:
■ One method of determination should be selected as it
is not possible to compare different measurement
methods.
