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

sensor.

4. If not already selected, select the Patient Size through the Patient Menu. Choices

are Adult, Pediatric or Neonate.
