Sensors
WARNING: Before use, carefully read the sensor Directions for Use , including all warnings, cautions,
and instructions.
WARNING: Do not immerse the sensor in water, solvents, or cleaning solutions (the sensor and
connectors are not waterproof). Do not sterilize by irradiation, steam, or ethylene oxide. See
the cleaning instructions in the directions for use for reusable pulse oximetry sensors.
WARNING: Before each use of SpO
2
sensors, assure that the sensor is intact. Damaged sensors (torn,
worn out [abraded], or exposed optical components, wires or metal) are prohibited for use.
Use of damaged sensors may compromise patient safety and may result in patient injury.
Protection of the monitor against the effects of the discharge of a cardiac defibrillator is
dependent upon the use of appropriate SpO2 cables and sensors listed in
Table 11 on
page 58 .
WARNING: Use only Nellcor sensors for SpO
2
measurements. Other sensors may cause improper
monitor performance.
WARNING: Do not use oximetry sensors during magnetic resonance imaging (MRI) scanning.
Conducted current could cause burns. The sensors may affect the MRI image and the MRI
unit may affect the accuracy of oximetry measurements.
WARNING: Tissue damage can be caused by incorrect application or use of a pulse oximetry sensor.
Inspect the sensor site as directed in the Instructions for Use. Do not apply the sensor too
tightly or by using excessive pressure. Do not wrap the sensor, apply supplemental tape, or
leave the sensor too long in one place. If the skin under the sensor becomes irritated, change
the location of the sensor.
CAUTION: Single-patient use sensors and adhesive sensors are intended for single-patient use only. Do
not transfer a single-use sensor or an adhesive sensor from one patient to a second patient.
Note: The oxygen transducers (sensors) used in this device can be categorized as surface devices contacting
skin for a limited duration of time. The sensors have passed the recommended biocompatibility testing
and are therefore in compliance with ISO 10993–1.
Note: Because light absorption by hemoglobin is wavelength dependent and because the mean wavelength of
LEDs varies, a monitoring system must know the mean wavelength of the sensor's red LED to
accurately measure SpO
2
. During monitoring, the monitoring system’s software selects coefficients that
are appropriate for the wavelength of that individual sensor's red LED; these coefficients are then used
to determine SpO
2
. Additionally, to compensate for differences in tissue thickness, the light intensity of
the sensor's LEDs is adjusted automatically. Together these features provide automatic calibration of the
SpO2 feature.
