Connecting an SpO2 Sensor to the Monitor

poor peripheral perfusion
Clean and remove any substances such as nail polish from the application site. Periodically check to ensure that
the sensor remains properly positioned on the patient.
Select an appropriate sensor, apply it as directed, and observe all warnings and cautions presented in the
directions for use accompanying the sensor.
High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps,
fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of an SpO
2
sensor. To prevent interference from ambient light, ensure that the sensor is properly applied, and cover the
sensor site with opaque material.
CAUTION: Failure to cover the sensor site with opaque material in high ambient light conditions may
result in inaccurate measurements
.
If patient movement presents a problem, try one or more of the following remedies:
•
Verify that the sensor is properly and securely applied.
•
Move the sensor to a less active site.
•
Use an adhesive sensor that tolerates some patient motion.
•
Use a new sensor with fresh adhesive backing.
If poor perfusion affects performance, consider using the MAX-R sensor; it obtains measurements from the
nasal septal anterior ethmoid artery, an artery supplied by the internal carotid. This sensor may obtain
measurements when peripheral perfusion is relatively poor.
Reading accuracy in the presence of low perfusion (detected IR pulse modulation amplitude between 0.03% and
1.5%) was validated using signals supplied by a patient simulator. SpO
2
and pulse rate values were varied
across the monitoring range over a range of weak signal conditions and compared to the known true saturation
and pulse rate of the input signals.
Connecting an SpO
2
Sensor to the Monitor
Before monitoring a patient with pulse oximetry, the appropriate SpO
2
sensor must be connected to the monitor
and to the patient.

:
1. Connect the SpO
2
extension cord firmly to the monitor SpO
2
sensor port, and then connect the appropriate
Nellcor SpO
2
sensor to the extension cord.
2. Connect the Nellcor SpO
2
sensor to the patient as described in its Directions for Use, using a Nellcor SpO
2
sensor extension cable.
3. When the SpO
2
sensor is plugged into the extension cable and connected to the monitor, the monitor will
immediately begin to search for a pulse. It will indicate
NO PULSE FOUND
and
SpO

SENSOR NOT
ON PATIENT until the time that the sensor is placed on the patient. This is classified as a Medium Priority
Alarm, and will generate a triple beep every thirty seconds. To avoid the alarm message and beeping, you
can connect the extension cable to the monitor, but wait to connect the SpO
2
sensor to the extension cable
until it is time to connect the patient to the monitor.
