Measurements
CAUTION:
Inaccurate readings may be caused by incorrect sensor
application or use; significant levels of dysfunctional
hemoglobins (i.e. carbohemoglobins or methemoglobin); or
intra-vascular dyes such as indocyanine green or methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a Xenon light source), bilirubin
lamps, fluorescent 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.
CAUTION:
Route cables neatly. Ensure cables, hoses, and wires are
kept away from patient’s neck to avoid strangulation. Keep
floors and walkways free of cables to reduce risk to
hospital personnel, patients, and visitors. If the sensor or
patient cable is damaged in any way, discontinue use
immediately.
NOTE:
Do not place the sensor on an extremity with an invasive
catheter or blood pressure cuff in place.
NOTE:
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 intervention.
The digital SpO

value displays on the SpO
2
LED (7), and the SpO
2
Pulse Rate displays on
the Pulse Rate LED (6).

If desired, adjust the beep volume. See section 3.10.1, “Setting the Alarm Volume, Key
Volume, and Pulse Volume, and NIBP End Tone Volume”, for details on adjusting the
beep volume.

NELLCOR
®
Sensors
NELLCOR
®
provides a family of sensors suitable for a wide variety of clinical settings and
patients. See package insert(s) for use and care instructions. Additional information is
available from Nellcor Puritan Bennett Inc. at www.nellcor.com.
3.11.3
Sequence for Establishing SpO
2
with Masimo
®
Pulse Oximetry
This is an optional feature.
1.
Select the appropriate sensor for the patient from the list of accessories in Chapter 5.0 .
2.
Attach the appropriate corresponding Patient Cable (P/N 0012-00-1099-02, 0012-00-
1652, 0012-00-1599, or 0012-00-1653) to the sensor and plug the other end of the
patient cable into the SpO
2
connector (20).
CAUTION:
When equipped with MASIMO® SpO2, use only MASIMO®
oxygen transducers including MASIMO LNOP®, MASIMO
LNCS® patient dedicated adhesive sensors and MASIMO PC
Series Patient Cable. Use of other oxygen transducers may
cause improper oximetry performance.
CAUTION:
Excessive ambient light may cause inaccurate SpO2
measurements. Cover the sensor with opaque materials.
