Oxygen saturation measurements derived from pulse oximetry are highly dependent on patient
conditions and proper placement of the sensor. Patient conditions such as smoke inhalation
might result in erroneous oxygen saturation readings. If the accuracy of any reading is in doubt,
verify the reading using another clinically accepted method, such as arterial blood gas
measurements.
The R Series Pulse Oximetry option is intended for use only with ZOLL/Masimo LNCS
sensors.
Measurement Complications
If the accuracy of any reading is suspect, first check the patient’s vital signs by alternate means
and then check the R Series Pulse Oximeter for proper functioning.
Inaccurate measurements may be caused by:
• Incorrect sensor application or use.
• Significant levels of dysfunctional hemoglobins (for example, carboxyhemoglobin or
methemoglobin).
• Intravascular dyes, such as indocyanine green or methylene blue.
• Exposure to excessive illumination, such as surgical lamps (especially those with a xenon
light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight.
• Excessive patient movement.
• Patient conditions, such as smoke inhalation.
• Venous pulsations.
• Certain nail aberrations, nail polish, fungus, and so on.
• Placement of a sensor on a limb with restricted blood flow, a blood pressure cuff, an arterial
catheter, or an intravascular line.
A weak pulse signal on the display might indicate a poorly applied sensor or a poorly chosen
monitoring site. Loss of pulse signal can occur when:
• The sensor is applied too tightly.
• There is excessive illumination from light sources, such as a surgical lamp, a bilirubin lamp,
or sunlight.
• A blood pressure cuff is inflated on the limb used for the oximeter sensor.
• Excessive patient movement.
• The patient has hypotension, severe vasoconstriction, or hypothermia.
• An arterial occlusion exists proximal to the sensor.
• The patient is in cardiac arrest or shock.

Connector and Sensors
The SpO

connector is located on the rear panel of the R Series unit. Use only ZOLL or
Masimo accessories and sensors with the R Series Pulse Oximetry option.
Each sensor is designed for application to a specific anatomical site on patients within a certain
weight range. To ensure optimal performance, use an appropriate sensor, apply it as described
in the sensor’s Directions for Use, and always observe all warnings and cautions.
