Warning
Oxygen saturation measurements using pulse oximetry are highly dependent on proper placement of the
sensor and patient conditions. Patient conditions such as shivering and 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.
Tissue damage can be caused by incorrect application or use of a sensor (e.g., wrapping the sensor too tightly,
applying supplemental tape, failing to periodically inspect the sensor site, leaving a sensor on too long in one place).
Refer to the Directions for Use provided with each sensor for specific instructions on application and use, and for
description, warnings, cautions, and specifications.
Sensors exposed to ambient light while not applied to a patient can exhibit semi-normal saturation readings.
Be sure the sensor is securely placed on the patient and check its application often to ensure accurate readings.
Before you use a Propaq CS monitor on a new patient, always turn off the monitor for a few seconds, then turn
it on again. This clears the prior patient’s trend values, alarm limit settings, and NIBP cuff inflation target.
Note
During SpO
2
monitoring, the monitor performs an SpO
2
self-calibration procedure every 15 minutes to help make sure
the SpO
2
channel is functioning properly. During the self-calibration, the SpO
2
waveform is displayed as a flat line for a few
seconds. After calibration, the SpO
2
monitoring resumes.
1. Attach the sensor to the patient according to the sensor manufacturer's instructions, observing
all warnings and cautions.
Use only NELLCOR accessories and sensors with the Propaq CS monitor SpO
2
option as listed in the
Protocol Systems Products and Accessories booklet. Each sensor is designed for application to a specific
site on a patient within a certain size range. To ensure optimal performance, use an appropriate
sensor and apply it as described in the sensor's Directions for Use. Always observe all warnings and
cautions. Consider using other types of listed sensors for different applications if you have problems
obtaining good measurements.
If excessive ambient light is present, cover the sensor site with opaque material to block the light.
Failure to do so may result in inaccurate measurements. Light sources that can affect performance
include surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.
If NIBP will be monitored while using SpO
2
, place the NIBP cuff on a different limb than the SpO
2
sensor to help reduce unnecessary SpO
2
alarms.
2. Plug the sensor into the SpO
2
sensor extension cable and plug the cable into the monitor, or
plug the sensor directly into the monitor.
3. Lock the connector in place by turning the locking ring clockwise until it stops.
The monitor displays STANDBY in the SpO
2
numeric window until it measures and displays the
SpO
2
value.
The monitor self-calibrates the SpO
2
channel whenever the monitor is first turned on, at least every 15
minutes thereafter, and whenever a sensor is connected to the SpO
2
channel. During calibration, the
SpO
2
waveform is momentarily flat.
As oxygen saturation increases and decreases, the pitch of the heart tone rises and falls.
