MASIMO SET® SpO2: Indications and Contraindications
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.
Loss of pulse signal can occur in any of the following situation:
the sensor is too tight
there is excessive illumination from light sources such as
surgical lamp, a bilirubin lamp, or sunlight
a blood pressure cuff is inflated on the same extremity as
the one with a SpO
the patient has hypotension, severe vasoconstriction,
severe anemia, or hypothermia
there is arterial occlusion proximal to the sensor
the patient is in cardiac arrest or is in shock
Sensors:
Before use, carefully read the MASIMO
use.
Use only MASIMO
Other oxygen transducers (sensors) may cause improper SpO
performance.
