NIBP Monitoring NIBP Measurements
7.4 NIBP Measurements
7.4.1 Manual NIBP Measurements
1. Select a blood pressure cuff that is appropriate for the size of the patient. Measure limb
for the best results.
NOTE: A cuff that is too narrow for the limb will result in
erroneously high readings. The correct size of the pressure
cuff for a given patient has, among other considerations, a
direct bearing on the accuracy of the obtained NIBP
measurements. Base selection of the cuff size on the limb
circumference of the patient. The design dimensions of the
cuffs and their intended uses are based on
recommendations of the American Heart Association.
NOTE: Cuffs become brittle as they age and sometimes develop
permanent folds that can leave temporary marks on the
limb. Any cuffs that exhibit this effect should be replaced.
NOTE: Ensure that the pressure tubes are not compressed or
restricted.
NOTE: The pressure on the limb may not fall to zero between
measurements if the cuff is wrapped too tightly. Therefore,
ensure that the cuff is properly applied.
NOTE: The skin is sometimes fragile (i.e., on pediatrics, geriatrics,
etc.). In these cases, a longer interval between
measurements should be considered to decrease the
number of cuff inflations over a period of time. In extreme
cases, a thin layer of soft roll or cotton padding may be
applied to the limb in order to cushion the skin when the
cuff is inflated. This measure may affect NIBP performance
and should be used with caution.
2. Attach cuff hose to NIBP Connector.
3. Apply the cuff to the patient. To reduce errors, the cuff should be adjusted for a snug fit.
Little or no air should be present within the cuff. Be sure the cuff lies directly against the
patient’s skin. No clothing should come between the patient and the cuff.
NOTE: The NIBP cuff should not be placed on a limb that is being
utilized for any other medical procedure. For example, an IV
catheter or an SpO 2 sensor.
4. If not already selected, select the Patient Size through the Patient Menu. Choices
are Adult, Pediatric or Neonate.
