Pulse CO-Oximetry Indications for Use

Pulse CO-Oximetry Indications for Use
The ZOLL E Series pulse CO-oximeter, with Masimo
Rainbow SET technology and the Rainbow series of
sensors, is indicated for the continuous noninvasive
monitoring of arterial oxygen saturation (SpO
2
), pulse
rate, carboxyhemoglobin saturation (SpCO), and/or
methemoglobin saturation (SpMet). The pulse
CO-oximeter is indicated for use on adult, pediatric, and
neonatal patients who are stationary or in motion in a
hospital or prehospital environment.
If the unit is configured for SpCO and/or SpMet
monitoring and a Rainbow sensor is attached to the
patient’s finger, then SpCO and/or SpMet values are also
continuously displayed. If a Red sensor is attached to the
patient (or an LNCS sensor with a Red patient cable),
then only the SpO
2
and pulse rate values are displayed.
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.
Measurement Complications
If the accuracy of any reading is suspect, first check the
patient's vital signs by alternate means and then check
the E Series pulse CO-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.
CO-oximetry Connector and Sensors
The CO-oximetry connector is located on the rear panel
of the E Series unit (see Figure 1). You can use only
ZOLL or Masimo accessories and sensors with the
E Series Pulse CO-Oximetry option.
Figure 1
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 the sensor as described in Directions for Use
included with each sensor.
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).
Setup
Set up the SpO
2
/SpCO/SpMet option as follows:
1. Inspect the E Series case and CO-oximetry cables
for damage.
2. Ensure that the sensor and cable are compatible
models before connecting them to the E Series unit
(see “CO-Oximeter Accessories” on page 10).
3. Attach the sensor to the patient and connect the
sensor to the CO-oximetry patient cable, if applicable
(see “Applying a 2-piece Reusable Sensor/Cable” on
page 4 or “Applying a Disposable Sensor” on
page 5).
If using a reusable sensor, make sure it opens and
closes smoothly and check for foreign material such
as tape or cotton on the emitter and detector
windows. Remove any substances that may interfere
with the transmission of light between the sensor's
light source and detector.
