CAUTIONS
Patient safety:
Do not place any clip-on sensor in a patient’s mouth or on a
patient’s nose or toe.
Do not place a clip-on finger sensor on a patient’s thumb or
across a child’s foot or hand.
The sensor disconnect error message and associated alarm
indicate that the sensor is either disconnected or the wiring is
faulty. The user should check the sensor connection and, if
necessary, replace the sensor, interconnect cable, or both.
Observe the sensor site frequently to assure adequate distal
circulation. Sensor sites should be checked at least every 2
hours and rotated at least every 4 hours.
Monitor performance:
Placing a sensor distal to an arterial line may interfere with adequate
arterial pulsation and compromise the measurement of SpO
2
.
Place the sensor so that the LEDs and the photodiode are
opposite each other.
3. Plug the SpO
2
sensor into the SpO
2
interconnect cable. Then plug the SpO
2
interconnect cable into the SpO
2
sensor connector.
4. Proceed with monitoring. SpO
2
measurements run continuously and can
run simultaneously with other measurements.

SpO

Hold-off Period
The hold-off period is defined as the 10 seconds that follows when the SpO
2
parameter switches from ready mode to operate mode. This hold-off period
helps prevent any nuisance alarms.
Parameter status alarms are not displayed and the derived SpO
2
value is not
checked against user-set limits while the SpO
2
hold-off period is active.
Alarm Timer
When an SpO
2
sensor is on for less than 2 minutes this is considered "spot
mode." The SpO
2
--- SENSOR OFF FINGER and SpO
2
E25 LOST PULSE alarms are
generated as low-priority alarms if they occur within the spot mode time. While
in spot mode, the length of spot mode operation is further increased by taking a
manual NIBP determination.
Under all other conditions, these alarms are generated as high-priority alarms. If
the low-priority alarms are not acknowledged within 1 minute, they escalate to
high-priority alarms.
