Preparing for SpO
2
monitoring 47
Connect the SpO
2
sensors only to the corresponding patient cable
and this only to the corresponding socket on VitaGuard®.
Do not use adhesive strip SpO
2
sensors on patients exhibiting aller-
gic reactions to adhesive strips or similar.
Securing sensors incorrectly, e.g. too tightly, can damage tissue.
Do not use damaged sensors. Replace sensors immediately if they
exhibit any damage.
Do not immerse the sensors in liquids and do not attempt to sterilize
them.
An improperly attached sensor can falsify measurements.
Do not attach the SpO
2
sensor to a limb that has or will have a
catheter or pressure cuff during monitoring.
Secure the sensors and cables so that they cannot harm, strangle, or
be swallowed by the patient. Always lay the patient cable at a safe
distance from the patient’s head and neck. Lay the patient cable
when monitoring small children inside their clothing so that it exits
at the foot. On larger children and adults you can, for example, lay
the patient cable so that it exits between the trousers and pullover.
To prevent damage, avoid all kinks, folds, and any other unnecessary
bends in the sensor cable.
6.2 Operation of SpO
2
sensors
SpO
2
sensors consist of a transmitter diode (referred to as “transmit-
ter” in the following) and a receiver. The transmitter is identified by
the red star symbol on the adhesive strip. The receiver is identified by
its round window and the white plastic part on the adhesive strip
behind it.
The transmitter emits light, the receiver detects this light. When this
light penetrates arterial blood vessels, the composition and intensity
of the light picked up by the receiver change.
