If the accuracy of any measurement does not seem
reasonable, first check the patient's vital signs by alternate
means and then check the SpO
functioning properly.
NOTE:
Because the SpO

distributed, only about two-thirds of the SpO
measurements can be expected to fall within ±Arms of the value
measured by a co-oximeter.
An inaccurate measurement can be caused by:
• Incorrect sensor application or use.
• Significant levels of dysfunctional hemoglobins (such as
carboxyhemoglobin or methemoglobin).
• Intravascular dyes (such as indocyanine green or
methylene blue).
• Exposure to excessive illumination; such as, a surgical
lamp (especially one with a xenon light source), bilirubin
lamp, fluorescent light, infrared heating lamp, or direct

sunlight.
• Prolonged and/or excessive patient movement.
• Venous pulsations.
