7.4 Applying the Sensor
WARNING

If the sensor is too tight because the application site is too large or becomes too
large due to edema, excessive pressure for prolonged periods may result in
venous congestion distal from the application site, leading to interstitial edema
and tissue ischemia.
NOTE

Place the SpO
2
sensor so that the light source is against the application site.

Check if the sensor is in normal condition before monitoring. Do not use the
SpO
2
sensor if the package or the sensor is found damaged.

Do not apply the sensor on a limb with an intravenous infusion or arterial
catheter in place.
1. Select an appropriate sensor according to the module type, patient category and
weight.
2. Clean the application site. For example, remove colored nail polish.
3. Apply the sensor to the patient.
4. Select an appropriate adapter cable according to the connector type and plug this
cable into the SpO
2
connector.
5. Connect the sensor cable to the adapter cable.
