Chapter 9: SpO2 & Rainbow Parameters Monitoring
Warning
The pulse co-oximeter is not an apnea monitor.
Warning
The pulse co-oximeter should not be used for arrhythmia analysis.
Warning
Pulse oximetry can overestimate the SpO2 value in the presence of Hb-CO, Met-Hb or dye
dilution chemicals.
Warning
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 and result in inaccurate measurements. To
prevent interference from ambient light, cover the Rainbow sensor with an ambient light
shield.
Caution
When patients are undergoing photodynamic therapy they may be sensitive to light
sources. Pulse oximetry may be used only under careful clinical supervision for short time
periods to minimize interference with photodynamic therapy.
Caution
If using pulse oximetry during full body irradiation, keep the sensor out of the radiation
field. If the sensor is exposed to the radiation, the reading might be inaccurate or the
instrument might read zero for the duration of the active irradiation period.
Caution
To ensure that alarm limits are appropriate for the patient being monitored, check the
limits each time the pulse co-oximeter is used.
Caution
Variation in haemoglobin measurements may be profound and may be affected by
sampling technique as well as the patient's physiological conditions. Any result exhibiting
inconsistency with the patient's clinical status should be repeated and/or supplemented
with additional test data. Blood samples should be analyzed by laboratory instruments
NOTE:
SpO2 module updates SpO2 and pulse rate values every 1 sec.
