DEFIGARD/PHYSIOGARD Touch 7
4.6.1 Inaccurate or incorrect measurement result

Only use SpO
2
, SpCO and SpMet sensors listed in the order information for the
DEFIGARD/PHYSIOGARD Touch 7. Other oxygen transducers (sensors) may
lead to improper performance.

The information in this user guide does not overrule any instructions given in the
sensor's user guide, which must be consulted for full instructions.

Never use the pulse oximeter as the sole means of monitoring a patient or as an
apnoea monitor- always use the pulse oximeter in combination with an ECG
trace.

Never use a pulsoximeter during MR imaging. Induced current could potentially
cause burns and the pulse oximetry may affect the image and accuracy of the
measurements.

Tissue damage can be caused by incorrect application or use of a sensor.
Inspect the sensor application location as described in the sensor directions to
ensure skin integrity and correct positioning and adhesion of the sensor.

Do not use damaged patient cables, damaged sensors or sensors with exposed
optical components.

Change the position of the sensor at least every 4 hours, and every 2 hours if
the perfusion is low.

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.

Inaccurate measurements can be caused in general by:
– Improper sensor application
– Low arterial perfusion
– Motion artefact
– Elevated levels of bilirubin
– Intravascular dyes such as indocyanine green or methylene blue

Inaccurate measurements SpCO and SpMet can be caused by:
– Abnormal haemoglobin levels
– Low arterial oxygen saturation levels including altitude induced hypoxaemia

Inaccurate SpO2 measurements can be caused by:
– Elevated levels of COHb or MetHb: High levels of COHb or MetHb may occur
with a seemingly normal SpO2. When elevated levels of COHb or MetHb are
suspected, laboratory analysis (co-Oximetry) of a blood sample should be per-
formed.
– Externally applied colouring and texture, such as nail polish, acrylic nails, glitter,
etc.
– Severe anaemia

Interfering substances: Dyes or any substance containing dyes that change
usual blood pigmentation may cause erroneous readings.

If SpO2 values indicate hypoxaemia, a laboratory blood sample should be taken
to confirm the patient’s condition.
