◆
Only use the SpO
2
probes provided by manufacturer for SpO
2
measurements. Other
SpO
2
probes may cause improper performance.
◆
Inaccurate measurements may be caused by:
◆
Do not use the SpO
2
probe with exposed optical components.
◆
Excessive patient movement may cause inaccurate measurements.
◆
Tissue damage can be caused by incorrect application or use of the probe, for example
by wrapping the probe too tightly. Inspect the probe site to ensure skin integrity and correct
positioning and adhesion of the probe. More frequently inspection should be taken depend
on different patients if necessary.

CHAPTER 5 Take a Measurement
Before taking a measurement:
Note:
If there is no
fi
nger in the probe, “Finger Out!!” will be shown.
Warnings!
◆
The measurement would not be performed if the following instances come across in operation:
• Shock
• Low temperature of hand
• Have taken vascular activity medicine
• Anemia
• carboxyhemoglobin
• methemoglobin
• methylene blue
• Indigo carmine
●
Select the suitable probe in terms of type and dimension.
●
Plug probe into SpO
2
socket on top panel of pulse oximeter.
●
Clip the patient
fi
nger to the rational position of the probe as the illustration as Fig.5-1.
• Incorrect application or use of probe
• Signi
fi
cant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or methemoglobin)
• Intravascular dyes such as indocyanine green or methylene blue
• Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon
light source), bilirubin lamps,
fl
uorescent lights, infrared heating lamps, or direct sunlight
• High-frequency electro surgical interference and de
fi
brillators
• Venous pulsations
