Problem
When I try to change CO
the patient monitor, a message
says I must use the Acuity System
units.
When I select SpO
rate source, ECG remains the
source.
SpO or NIBP are not displayed in

the Virtual Monitor when I try to
turn on either for display.
A connected monitor equipped
with IPI does not display an IPI
value in the Virtual Monitor.
An NIBP reading seems
inaccurate.
"??:??:??" is shown to indicate the
time of an NIBP measurement.
When NIBP measurements are
taken while a monitor is
temporarily disconnected from an
Acuity System, the NIBP values
are not transferred to the Acuity
System review windows.

You can select up to three waveforms for display. If you select more than three, the
three highest priority waveforms are displayed.

In addition, NIBP numerics display for only one hour after an NIBP measurement is
taken.
This occurs under these circumstances:
• The monitor's Patent Mode is set to neonate. Make sure that the monitor is set
to adult or pediatric mode.
• Not all parameters used to calculate IPI are active. Make sure that etCO

WARNING If a noninvasive blood pressure reading is suspect, repeat the
measurement, watching a manometer (if the monitor has one) to verify the
reading. If you are still uncertain about the reading, use another method.
This occurs under either of these circumstances:
• The monitor was connected to the Acuity System during NIBP measurement,
and the monitor was then disconnected from and reconnected to the Acuity
System.
• The monitor was not connected to the Acuity System during NIBP
measurement, and then the monitor was connected to the Acuity System.
Open the NIBP status window at the patient monitor to read the time of the NIBP
value.
If an NIBP measurement is taken within two minutes before connection to an Acuity
System or two minutes following disconnection from an Acuity System, the reading
might not transfer to the Acuity System.
Take NIBP measurements after the monitor is connected to the Acuity System, to
ensure NIBP trending.
