-?-.
Source - MX40
Soft
The update period of
displayed values is
extended due to an NBP
measurement on the same
limb or an excessively
noisy signal.
If NBP is not active, check the
sensor placement. Reposition
the sensor on patient, or replace
sensor.

T LOW PERF
Source - Monitor
Soft
Accuracy may be reduced
due to low perfusion. Data
displayed with ?.
Increase perfusion. Change
sensor site. Avoid site distal to
BP cuff or intra-arterial line.
Warm the site.

T INTERFERENCE
Source - MX40
Hard
Level of ambient light or
level of electrical
interference are so high
that the SpO
2
sensor
cannot measure SpO
2
and
pulse rate.
Reduce ambient light to sensor
or electrical noise sources.
