Limitations
Patient
Movement
Measurements will be unreliable or cannot be taken if the patient is moving,
shivering or having convulsions. These motions may interfere with the detection of
the arterial pressure pulses. In addition, the measurement time will be prolonged.
Cardiac
Arrhythmia's
Measurements will be unreliable and may not be possible if the patient's cardiac
arrhythmia has caused an irregular heartbeat. Thus the measuring time will be
prolonged.
Heart/lung
Machine Measurements will not be possible if the patient is connected to a heart or lung
machine.
Pressure
Changes Measurements will be unreliable and may not be possible if the patient's blood
pressure is changing rapidly over the period of time during which the arterial
pressure pulses are being analysed to obtain the measurement.
Severe Shock
If the patient is in severe shock or hypothermia, measurements will be unreliable
since reduced blood flow to the peripheries will cause reduced pulsation of the
arteries.
Heart Rate
Extremes Measurements cannot be made with a heart rate of less than 40 bpm or greater than
240 bpm.
Larger Patients Thick layers of body fat will reduce measurement accuracy as this dampens the
compressive shock of the cuff on the bodies arteries
4.3 Placement and Operation
1. Select the correct NIBP Cuff.
Note: The width of the cuff should be either 40% of the limb circumference (50% for
neonates) or 2/3 of the upper arm length. The inflatable part of the cuff should be long
enough to encircle 50-80% of the limb. The wrong size of cuff can cause erroneous readings.
If the cuff size is in question, then use a larger cuff.
2. Connect the cuff to the NIBP extension hose using the bayonet.
The connection used as standard for our BP cuff is a metal, male barbed bayonet valve as pictured
below, this connection allows the BP cuffs to be interchangeable.
Warning - Avoid compression or restriction of pressure tubes, and make sure the tube
between the cuff and the monitor are not kinked or blocked.
3. Once attached you will need to place the cuff snugly around the extremity being used.
Make sure that the cuff edge falls within the range of the marks ‘<->’. If it does not, use a larger
or smaller cuff that fits better.
