Rainbow SET, Masimo SET Sensor Placement
If the SpO

, SpCO, SpMet or SpHb readings are questionable or unavailable, do the following:
■ Make sure the emitter and detector are aligned directly opposite each other.
■ Select a site where the distance between the emitter and detector is minimized.
■ Wipe the sensor site with a 70% isopropyl alcohol pad or rubefacient cream (10-30%
methyl salicylate and 2-10% menthol) for 20-30 seconds to increase perfusion. However,
strong vasodilator creams, such as nitroglycerin paste, are not recommended.
■ If possible, remove electrical noise sources such as electro-surgical devices or other
electrical/electronic equipment. If these solutions are not possible, operate the Rad-87 on
battery power, or try plugging the instrument into a different electrical outlet.
■ If artificial nails or excessive fingernail polish are present, select another site or remove
the polish/artificial nails.
■ If possible, ensure that the sensor is placed in a location with low ambient light. Although
the Rad-87 with integrated Masimo Rainbow SET technology has significant immunity to
ambient light, excessive ambient light may cause readings to be incorrect.
CAUTION:
• If any measurement seems questionable, first check the patient’s vital signs by
alternate means and then check the Pulse CO-Oximeter for proper functioning.
