When I select SpO

"??:??:??" is shown to indicate the
time of an NIBP measurement.
When NIBP measurements are
taken while a monitor is
temporarily disconnected from an

are not transferred to the Acuity

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.

In addition, NIBP numerics display for only one hour after an NIBP measurement is
taken.
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.
