Masimo SET SpO2: Indications and Contraindications
WARNINGS
Do not use the SpO
2
parameter during magnetic resonance
imaging (MRI). Adverse reactions include potential burns to
patients as a result of contact with attachments heated by the
MRI radio frequency pulse, potential degradation of the
magnetic resonance image, and potential reduced accuracy of
SpO
2
measurements. Always remove oximetry devices and
attachments from the MRI environment before scanning a
patient.
As with all medical equipment, carefully route patient cabling to
reduce the possibility of patient entanglement or strangulation.
The use of cardio-green and other intravascular dyes at certain
concentrations may affect the accuracy of the SpO
2
measurement.
The SpO
2
parameter is calibrated to read functional arterial
oxygen saturation. Significant levels of dysfunctional
hemoglobins such as carboxyhemoglobin or methemoglobin
may affect the accuracy of the SpO
2
measurement.
A functional tester cannot be used to assess the accuracy of a
pulse oximeter probe or a pulse oximeter monitor.
CAUTIONS
If any measurement does not seem reasonable, first check the
patient’s vital signs by alternate means and then check the
pulse oximeter for proper functioning.
Inaccurate measurements may be caused by:
 Incorrect sensor application or use
 Significant levels of dysfunctional hemoglobins (e.g.,
carboxyhemoglobin or methemoglobin)
 Intravascular dyes such as indocyanine green or
methylene blue
 Exposure to excessive illumination, such as surgical lamps
(especially ones with xenon light source), bilirubin lamps,
fluorescent lights, infrared heating lamps, or direct sunlight
(exposure to excessive illumination can be corrected by
covering the sensor with a dark or opaque material)
 venous pulsations
 placement of sensor on an extremity with a blood pressure
cuff, arterial catheter, or intravascular line
The pulse oximeter can be used during defibrillation, but the
readings may be inaccurate for a short time.
