APPLICATION TIPS
General Tips
•
Use only the probes listed in chapter 7 "Accessories". Apply the probes as described in their instructions for use.
Carefully observe all information and cautions given in these instructions.
•
Take care that the probe does not exert too much pressure when applied to avoid erroneous readings and blistering.
Inadequate oxygen supply to the skin, not heat, causes blisters.
•
Change the probe site at least every 24 hours to allow the skin to breathe.
•
Be careful to ensure continued circulation at the probe site.
•
Incident light may cause inaccurate readings. Cover the measuring site with a cloth, if necessary.
•
It may not be possible to measure SpO2 values, if cardiac output is determined at the same time by means of the
dye dilution technique.
•
It may not be possible to measure SpO2 values or the pulse rate, if the circulation is impaired (e.g. by a blood-
pressure cuff or by an extremely high vascular resistance).
•
Remove nail polish and artificial finger nails before applying the probe. Both may lead to inaccurate readings.
•
Do not apply the finger probe to the same arm as the blood-pressure cuff.
To minimize motion artifact
•
Use a new probe with fresh adhesive backing
•
Move the probe to a less active site
•
When monitoring SpO

during electrosurgical intervention, take care that
•
The device is powered from the internal battery or from a different power circuit than the electrosurgical unit
•
The ground pad is close to the surgical site
•
The probe is applied as far from the surgical site, the ground pad and the electrosurgical unit as possible.
In the presence of AC line interference
•
When interference signals from the power line are present, square waves may be displayed instead of the
plethysmogram. In this situation we recommend to disconnect the device from the power line and operate it on
battery power.
