Intended Use
The ZOLL M Series Pulse Oximeter, with Masimo SET®
technology and the LNCS series of sensors, is indicated
for the continuous noninvasive monitoring of arterial
oxygen saturation (SpO
2
) and pulse rate. The Pulse
Oximeter is indicated for use during both no-motion and
patient motion conditions for adult patients, and
no-motion conditions for pediatric and neonatal patients,
in a hospital and pre-hospital environment.
Oxygen saturation measurements using pulse oximetry
are highly dependent on proper placement of the sensor
and patient conditions. Patient conditions such as smoke
inhalation may result in erroneous oxygen saturation
readings. If pulse oximetry measurements are suspect,
verify the reading using another clinically accepted
measurement method, such as arterial blood gas
measurements.
The M 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 M Series Pulse Oximeter for proper functioning.
Inaccurate measurements may be caused by:
•
incorrect sensor application or use
•
significant levels of dysfunctional hemoglobins
(e.g., 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; exposure to
excessive illumination can be corrected by
covering the sensor with a dark or opaque material
•
excessive patient movement
•
venous pulsations
•
placement of a sensor on an extremity with a blood
pressure cuff, arterial catheter, or intravascular line
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 same
extremity as the one with a SpO
2
sensor attached
•
there is excessive patient movement.
•
the patient has hypotension, severe
vasoconstriction, or hypothermia
•
there is arterial occlusion proximal to the sensor
•
the patient is in cardiac arrest or shock

Connector and Sensors
The SpO
2
connector is located on the rear panel of the
M Series unit. Only ZOLL or Masimo accessories and
sensors can be used with the M 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, keep the sensor at the level of the patient's
heart, and always observe all warnings and cautions.
Tissue damage can result from incorrect application or
use of a sensor (e.g., wrapping the sensor too tightly,
applying supplemental tape, failing to periodically inspect
the sensor site). Refer to the Directions for Use provided
with each sensor for specific instructions on application
and use.
