Pulse Oximetry Measurement
SpO2 Monitoring 9-7
Sensor Type
When to Use
Reusable
You can use reusable sensors on different
patients after cleaning and disinfecting them.
For care and cleaning instructions, see the
instructions accompanying the sensors.
Reusable sensors should be changed to
another site every four hours or in accordance
with your clinical practice guidelines.
See the Directions for Use supplied by Nellcor®
Incorporated for instructions on preparation and
application of reusable sensors.
Disposable
Use disposable sensors only once and then
discard. However, you can relocate them to a
different patient-site if the first location does not
give the desired results. Do not reuse
disposable sensors on different patients.
Note — See the Instructions for Use supplied
by Nellcor® Incorporated for instructions on
preparation and application of disposable
sensors.
Sensor Application Safety Information
Warning
Failure to apply a sensor properly can reduce the accuracy of the SpO2
measurement.
 Loose/Tight sensor: If a sensor is too loose, it can compromise the
optical alignment or fall off. If it is too tight, for example because the
application site is too large or becomes too large due to edema,
excessive pressure can be applied. This can result in venous congestion
distal from the application site, leading to interstitial edema, hypoxia
and tissue malnutrition.
 Skin irritations or ulcerations can occur as a result of the sensor being
attached to one location for too long. To avoid skin irritations and
ulcerations, inspect the sensor application site every 2-3 hours, and
change the application site at least every 4 hours or according to clinical
practice guidelines.
 Venous Pulsation: Do not apply sensor too tightly as this results in
venous pulsation, which can severely obstruct circulation and lead to
inaccurate measurements.
