12.3.6 PRICO errors
Inaccurate measurements can be caused by:
• Excessive patient movement
• Exposure to excessive illumination, such as surgical lamps (especially those with a xenon light
source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight (correct
exposure to excessive illumination by covering the sensor with a dark or opaque material)
• Incorrect sensor application or use
• Intravascular dyes such as indocyanine green or methylene blue
• Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line.
• Significant levels of dysfunctional hemoglobins (for example: carboxyhemoglobin or
methemoglobin)
• Venous pulsation
Loss of pulse signal can occur in any of the following situations:
• The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
• The patient is in cardiac arrest or shock
• The sensor is too tight
• There is arterial occlusion proximal to the sensor
• There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp, or
direct sunlight
An alarm condition due to reached alarm limit is displayed with a Red alarm icon at the
corresponding alarm limit and as a flashing text with Yellow background in the Information bar.
