• Patient Movement
Measurements will be unreliable or may not be possible 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. The measuring time thus will be prolonged.
• Heart-lung Machine
Measurements will not be possible if the patient is connected to a heart-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 analyzed 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 can not be made at a heart rate of less than 40 bpm and greater than 240 bpm.
