5-2 EarlyVue VS30 Instructions for Use
WARNING
Use only approved accessories and sensors with the monitor. The use of unapproved accessories and
sensors can diminish monitor performance and/or safety.
For complete information on applying a sensor, see the Instructions for Use provided
with the sensor. For information about compatible SpO
2
sensors, see
Chapter 15, “Approved Accessories and Sensors.”
If an SpO
2
value does not seem reasonable, use the pleth wave and perfusion index to
assess the signal quality. If the perfusion value is low (three or fewer solid segments in
the bar), try adjusting the sensor, choosing a different sensor site, or using a different
type of sensor.
Caution
Do not apply the blood pressure cuff to the same side of the body as the one to which an SpO
2
sensor is attached because the cuff inflation disrupts SpO
2
monitoring and leads to nuisance alarms.
Note
SpO
2
alarms are suppressed when NBP is being measured on the same limb as SpO
2
. If
the SpO
2
measurement is delayed for more than 30 seconds (due to an excessively noisy
signal or because you are trying to measure NBP and SpO
2
on the same limb), the SpO2
Extd Update alarm occurs and the numeric pane display alternates between the
measurement value and a question mark (-?-).
Connecting SpO

Cables
Connect the sensor cable to the SpO
2
port on the left side panel, as shown in the
illustration. If the sensor uses an adapter cable, plug the sensor into the adapter cable,
and then plug the adapter cable into the SpO
2
port.
