11 Monitoring NBP
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.
Measurement Limitations
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:
• if a regular arterial pressure pulse is hard to detect
• with cardiac arrhythmias
• with excessive and continuous patient movement such as shivering or convulsions
• 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 the
• on an edematous extremity.
Measurement Methods
There are three methods of measuring NBP:
• Manual - measurement on demand.
• Auto - continually repeated measurements (between one and 120 minute adjustable interval).
• Sequence - up to four measurement cycles which will run consecutively, with number of
measurements and interval between them configurable for each cycle.
• STAT - rapid series of measurements over a five minute period, then the monitor returns to the
previous mode. Use only on supervised patients.
Reference Method
The NBP measurement reference method can be Auscultatory (manual cuff) or Invasive (intra-
arterial). For further information, see the Application Note on NBP supplied on the monitor
documentation CD-ROM.
In Adult and Pediatric mode to check the current setting, select Main Setup -> Measurements
-> NBP, and check whether the Reference setting is set to Auscultatory or Invasive. This
setting can only be changed in Configuration Mode.
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.
