Troubleshooting
NIBP: Retry Pump Higher
1
A measurement has been
attempted but no reading
was possible. This results
from inadequate cuff
inflation pressure.
1
Retry will be attempted.
2
Check that appropriate
patient size is set.
3
Pre-set initial inflation
pressure.
NIBP: Retry
1
Cuff is loosely wrapped.
The cuff may be too
loosely wrapped or not
attached at all.
2
Weak signal. The pulse of
the patient may be too
weak or the cuff is loosely
wrapped.
3
Excessive motion. In
measurement, signals
contain motion artifact or
too much interference.
4
Time-out. Measurement
takes more than 120
seconds in ADU/PED
mode and 90 seconds in
NEO mode.
5
Retry Overpressure or
bad measurement.
1
Retry will be attempted.
Check for leaks and
quality of peripheral
pulses. Decrease patient
movement. Switch cuff to
another limb.
NIBP: Initialization Error
1
During the IBP module
power-on, as the IBP
module communication
stops, system fails to
communicate with
module.
1
Contact Technical
Support.
NIBP: Communication Stop
1
As the Resp module
communication stops, the
data packets sent by the
module can not be
received.

SpO
2
: No Sensor
1
Sensor is not plugged in
to the monitor.
1
Plug the sensor into the
monitor.
SpO
2
: Sensor Off
1
Sensor may not be
connected to the patient.
1
Check patient connection.
SpO
2
: Interference
(Masimo/Nellcor Only)
1
Noise detected on the
pulse signal prevents
pulse discrimination.
1
Decrease patient motion,
check sensor.
SpO
2
: Pulse Search
1
Hardware settings are
being adjusted in order to
discriminate a pulse
waveform.
1
Change to site where
pulse is stronger if patient
is vasoconstricted.
2
Change or readjust
sensor if loose.
SpO
2
: No Pulse (DPM/Nellcor
Only)
1
No detectable pulse is
measured.
1
Check to patient
connection and patient
status.
