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.
NBP
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.
