The sensor is too tight.
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.
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
There is arterial occlusion proximal to the sensor.
The patient is in cardiac arrest or is in shock.
NOTE: See SP02 Sensor Specifications Table on page 45, the range of the peak wavelengths and maximum optical
output power of the light emitted by the pulse oximeter probe, which can be especially useful to clinicians.
NOTE: This device does not include an alarm system that detects an SpO2 or pulse rate physiological alarm condition.
This device is not designed for long-term monitoring and should only be used for spot-check measurements.
System Description:
The SunTech CT40 spot check device with pulse oximetry module consists of a base CT40 device for the display of
SpO2 measurement data and other user information, either a ChipOx or Masimo SET SpO2 module which is attached
to the CT40 base unit as described in
Section 2
, and the specific reusable pulse oximeter probe and/or cable that
comes packaged with each module. Device setup is described in more detail in
Section 2
. Both the Masimo
®
SET and
ChipOx SpO
2
modules are calibrated to display functional oxygen saturation (SpO
2
).
Taking SpO
2
Measurements:
1. Insert a finger (preferably the index, middle or ring finger) into the SpO2 sensor until the end of the finger reaches
the finger stop. Do not use the thumb.
2. The fingernail should face the side with the red light. Make sure that long fingernails do not interfere with proper
finger position
3. An SpO
2
reading will be displayed after a few seconds. Remove the finger from the SpO
2
sensor, and the last
measurement will be displayed and flashed.
4. If the sensor is not removed from the finger, SpO
2
readings will be automatically stopped after 10 minutes of
continuous measurement, and the last measurement will be displayed and flashed.
5. To start a new measurement, re-apply the SpO
2
sensor to the finger as described in Step 1.
NOTE: If the signal quality from the sensor drops below 90%, no measurement will be displayed in the SpO
2
section
, and the percent symbol
will begin flashing. Check sensor for correct placement and usage.
Special Notes for Masimo
®
SET SpO
2
module:
NOTE: Possession or purchase of this device does not convey any express or implied license to use the device with
unauthorized sensors or cables which would, alone or in combination with this device, fall within the scope of one or
more of the patents relating to this device.
NOTE:
If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by alternate
means and the check the MS board pulse oximeter for proper functioning.
NOTE: A functional tester cannot be used to assess the accuracy of a Masimo pulse oximeter sensor or pulse oximeter.
Using Clinical Dynamics SmartSat SpO2 simulator, the device can display the entire range of SpO2 values.
Masimo
®
Sensors:
Before use, carefully read the M-LNCS
TM
DCI/DCIP sensor directions for use, which includes cleaning and disinfection
instructions.
