13.3 NIBP Measurement Limitations
Measurements are impossible with heart rate extremes of less than 30 bpm or greater than 300 bpm, or if the
patient is on a heart-lung machine.
The measurement may be inaccurate or impossible in the following situations:
■
If a regular arterial pressure pulse is hard to detect;
■
With excessive and continuous patient movement such as shivering or convulsions;
■
With cardiac arrhythmias;
■
Rapid blood pressure changes;
■
Severe shock or hypothermia that reduces blood flow to the peripheries;
■
Obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from the artery.
13.4 Measurement Modes
There are three modes of measuring NIBP:
■ Manual: measurement on demand.
■ Auto: continually repeated measurements at set intervals.
■ STAT: continually rapid series of measurements over a five minute period, then return to the previous
mode.
13.5 NIBP Display
The NIBP display shows numerics only as below. Your display may be configured to look slightly different.
(1) Measurement mode (2) NIBP unit: mmHg or kPa
(3) Mean pressure at the completion of measurement, or cuff pressure during the measurement.
(4) Diastolic pressure (5) NIBP prompt message
(6) Systolic pressure (7) Time of last measurement
