cause the sensor to peel
off.
(RAM) Sensor
Initializing
• Device is checking the sensor
for proper function and
performance.
• If values are not displayed
within 30 seconds,
disconnect and reconnect
sensor. If values are still
not displayed, replace
with a new sensor.
(Pulse CO-Ox) Low
Perfusion Index
• Signal strength is too weak. • Move sensor to better
perfused site. See
Troubleshooting
Measurements.
(Pulse CO-Ox) Low
Signal IQ
• Indicates low signal
confidence in the value
displayed due to poor signal
strength.
• Ensure proper sensor
application. Move sensor
to a better perfused site.
See Signal IQ Indicators
on page 82.
(Pulse CO-Ox) Pulse
Search
• Device is searching for pulse. • If device fails to display
within 30 seconds,
disconnect and reconnect.
If pulse search continues,
move sensor to better
perfused site.
(Pulse CO-Ox)
Interference
Detected
or
(RAM) Interference
Detected
• High intensity light (pulsating
strobe lights, excessive
ambient light sources such as
surgical lights or direct
sunlight) or other monitor
displays.
• Incorrect monitor line

• Place a Masimo Optical
Light Shield over the
sensor.
• Adjust the Line Frequency
to the correct Hz setting.

2
Only Mode
• Occurs during an unsuccessful
sensor initialization/pulse
search routine or during
monitoring.
• See the directions for use
provided with your sensor.
Use a Masimo light shield
