9 Monitoring NBP
Unattended measurement: Use clinical judgement to decide whether to perform frequent
unattended blood pressure measurements in cases of severe blood clotting disorders because of the
risk of hematoma in the limb fitted with the cuff.
If you spill liquid onto the equipment or accessories, particularly if there is a chance that it can get
inside the tubing or the measurement device, contact your service personnel.
Measurements are impossible with heart rate extremes of less than 40 bpm or greater than 300 bpm, or
if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible:
with excessive and continuous patient movement such as shivering or convulsions
if a regular arterial pressure pulse is hard to detect
with cardiac arrhythmias
with rapid blood pressure changes
with severe shock or hypothermia that reduces blood flow to the peripheries
with obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from
on an edematous extremity.
The effectiveness of this sphygmomanometer has not been established in pregnant, including pre-
There are four modes for measuring NBP:

previous mode. Use only on supervised patients.
The measurement reference method can be Auscultatory (manual cuff) or Invasive (intra-arterial). For
further information, see the Application Note supplied on the monitor documentation DVD.
In Neonatal mode, to comply with safety standards, invasive is always used as the reference method.
This setting cannot be changed and is not visible in any operating mode.
