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

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