Problem Explanation
When I try to change CO
2
units at
the patient monitor, a message
says I must use the Acuity System
units.
CO
2
units are an Acuity System installation choice set by your system administrator.
Acuity System requires a single CO
2
unit to ensure that the CO
2
units are displayed
correctly.
When I select SpO
2
as the pulse
rate source, ECG remains the
source.
When ECG is monitored and C-LOCK is on, ECG is chosen as the heart rate source.
SpO
2
or NIBP are not displayed in
the Virtual Monitor when I try to
turn on either for display.
You can select up to three waveforms for display. If you select more than three, the
three highest priority waveforms are displayed.
ECG is always displayed when it is monitored, and P1, P2, P3, P4, and CO
2
take
priority over other selections. If you want to display SpO
2
or NIBP, turn off P1, P2, P3,
P4, and CO
2
.
In addition, NIBP numerics display for only one hour after an NIBP measurement is
taken.
A connected monitor equipped
with IPI does not display an IPI
value in the Virtual Monitor. 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
2
,
Respiration Rate, SpO
2
,and Pulse Rate are are being monitored.
An NIBP reading seems
inaccurate. 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.
“??:??:??” is shown to indicate the
time of an NIBP measurement. 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.
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. 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.
