1.3.10.2 Sequence for establishing SpO2 with Nellcor® Pulse Oximetry*
* This feature applicable only if available or installed on your unit.
1.Select the appropriate sensor for the patient from Page 3-28
2. Plug the sensor directly into the SpO2 connector (15) or if necessary, use a Nellcor®
SC10 extension cable. NOTE: Do not place the sensor on an extremity with an invasive
catheter or blood pressure cuff in place.

CAUTION:
When equipped with Nellcor® Sp02, use only Nellcor® oxygen transducers
including Nellcor® Oxisensor™ patient dedicated adbesive sensors. Use of other
oxygen transducers may cause improper oximeter performance.
Tissue damage or inaccurate measurements may be caused by incorrect sensor
application or use, such as wrapping it too tightly, applying supplemental tape,
Sailing to inspect the sensor site periodically, or failing to position it appropriately.
Carefully read the sensor directions for use, the Accutorr Plus operating
instructions, and all precautionary information before use.
Excessive ambient light may cause inaccurate measurements. Cover the sensor
with opaque materials.
Inaccurate readings may be caused by incorrect sensor application or use;
significant levels of dysfunctional hemoglobins, (i.e. carbobemoglobins or
methemoglobin); or intra-vascular dyes such as indocyanine green methylene blue;
exposure to excessive illumination, such as surgical lamps (especially ones with à
Xenon light source), bilirubin lamps, florescent lights, infrared heating lamps,
or direct sunlight; excessive patient movement; venous pulsations; electro-surgical
interference; and placement of a sensor on an extremity that has a blood pressure
cuff, arterial catheter, or intra-vascular line.
In certain situations in which perfusion and signal strength are low, such as in
patients with thick or pigmented skin, inaccurately low SpO2 readings will
result. Verification of oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting any therapy or
interventation.
If the sensor or patient cable is damaged in any way, discontinue use
immediately. To prevent damage do not soak or immerse the sensor in any liquid
solution. DO NOT ATTEMPT TO STERILIZE.
3. The digital SpO2 value and SpO2 Pulse Rate will be displayed on che $pO2 and Pulse
Rate LED's.
4, If desired, adjust the beep volume. See Section 3.7, "Setting the Alarm Volume and
Beep Volume", for details on adjusting the beep volume.
