SELECTING A SENSOR
When selecting a sensor, consider, the patient’s weight, the adequacy of perfusion, the available
sensor sites, and the duration of monitoring. For more information refer to the following table or
contact your Sales Representative. Use only sensors and sensor cables. Select an appropriate
sensor, apply it as directed, and observe all warnings and cautions presented in the Directions for
Use accompanying the sensor.
High intensity extreme lights (such as pulsating strobe lights) directed on the sensor, may not
allow the sensor to obtain vital sign readings. High ambient light sources such as surgical lights
(especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating
lamps, and direct sunlight can interfere with the performance of the sensor. To prevent
interference from ambient light, ensure that the sensor is properly applied, and cover the sensor
site with opaque material, if required. Failure to take this precaution in high ambient light
conditions may result in inaccurate measurements.
SENSOR APPLICATION INSTRUCTIONS
Unless indicated otherwise in the directions for use, reposition reusable sensors at least every 4
hours and for adhesive sensors inspect the site at least every 8 hours or sooner. If indicated by
circulatory condition or skin integrity, reapply to a different monitoring site.
Sensors
Sensors must be used with the D-MAS CO-Oximeter to enable measurement of
Carboxyhemoglobin (SpCO) and Methemoglobin (SpMet). Sensors will only function with
instruments containing SET Technology or licensed to use Rainbow compatible sensors. Rainbow
sensors connect to the device directly or with a patient cable.
RAINBOW REUSABLE SENSORS
