Chapter 9: SpO2 & Rainbow Parameters Monitoring
Caution
If "SpO2 LOW PERFUSION" message is frequently displayed, find a better perfused
monitoring site. In the interim, assess the patient and, if indicated, verify oxygenation
status through other means.
Warning
Prolonged and continuous monitoring may increase jeopardy of unexpected change of
dermal condition such as abnormal sensitivity, vesicle, repressive putrescence, and so on. It
is especially important to check the sensor placement of neonate and patient of poor
perfusion. Check per 2-3 hours the sensor placement and move it when the skin
deteriorates. More frequent examinations may be required for different patients.
Warning
Tissue damage or inaccurate measurement can be caused by incorrect application or use of
an SpO2 sensor, for example by wrapping the sensor too tightly or by applying
supplemental tape.
Warning
Loss of pulse signal can occur when
● The patient is in cardiac arrest or in shock.
● The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
● There is arterial occlusion proximal to the sensor.
