Patient Monitor User Manual Monitoring SpO
2
- 111 -
WARNING
4 Use only EDAN permitted sensors and extension cables with the monitor. Other
sensors or extension cables may cause improper monitor performance and/or minor
personal injury.
5 High oxygen levels may predispose a premature infant to retrolental fibroplasia. If this
is a consideration do NOT set the high alarm limit to 100%, which is equivalent to
switching the high limit alarm off.
6 When serious arrhythmia is present, the SpO
2
pulse rate may differ from ECG heart
rate but this does not indicate an inaccurate PR (SpO
2
) value.
NOTE:
1 Avoid placing the sensor on extremities with an arterial catheter, intravascular venous
infusion line, or inflated NIBP cuff. When measuring SpO
2
on the limb with inflated
NIBP cuff, please turn on the NIBP Simul function.
2 When a trend toward patient deoxygenation is indicated, analyze the blood samples
with a laboratory co-oximeter to completely understand the patient’s condition.
3 SpO
2
waveform is not directly proportional to the pulse volume.
4 The device is calibrated to display functional oxygen saturation.
5 A Functional tester or simulator can not be used to assess the SpO
2
accuracy.
However, it can be used to demonstrate that a particular monitor reproduces a
calibration curve that has been independently demonstrated to meet a particular
accuracy.
6 If the surrounding temperature increases, the operator should pay attention to the site
of poor perfusion, and increase the frequency of checking the skin and changing the
measurement site to prevent burns. If the initial skin temperature is less than 35°C,
the temperature of all the listed sensors on the skin will not exceed 41°C during
working.
10.3 Measuring SpO
2
1. Select the correct patient category setting (adult/pediatric and neonatal), as this is used to
optimize the calculation of the SpO
2
and pulse numerics.
2. During measurement, ensure that the application site:
– has a pulsatile flow, ideally with a good circulation perfusion.
– has not changed in its thickness, causing an improper fit of the sensor.
Measurement Procedure
1. Switch on the monitor.
2. Attach the sensor to the appropriate site of the patient finger.
3. Plug the connector of the sensor extension cable into the SpO
2
socket on XM module or V-
SpO
2
module.
