Appendix Newborn NIBP Technique
6.9 Newborn NIBP Technique
Newborn patients present unique obstacles to NIBP measurement. Their vital signs can
change from moment to moment, and their tiny physiological signals are very prone to noise
interference. The following suggestions will help you to obtain the best possible NIBP
measurement.
Try to measure infants when they are calm. A kicking/crying baby may disturb or jiggle
the cuff, causing noise within the system and, as a result, yielding unstable blood pressure
readings. If necessary, hold the cuffed limb steady, but do not impede circulation; do not
hold onto the cuff and do not “pat” the cuffed limb to comfort the child.
Try the calf. Irritable newborns will react to the cuff pressure but may tolerate the calf
better than the arm. Place the cuff just above the ankle.
Use the correct size cuff. Mindray DS offers Newborn and Infant size cuffs. When
applying, verify the cuff’s “Index” line falls between the “Range” lines.
Try disposable cuffs. Disposable cuffs are more pliant than the reusable ones. They
generally fit really tiny infants better.
Place the cuff lightly. If the cuff is too snug, it won’t work properly. On infants, you should
be able to easily move the cuff over the limb.
Remember NIBP cannot be taken under all conditions. Even manual methods, employing a
sphygmomanometer and stethoscope, will not work on unstable or active patients.
