Spectra Alerts: Resetting Alerts
Resetting Alerts
If you do not agree with an alert (see “False Pattern Recognition” and “Mode
Switching”), you can clear the data being used via the Alert field on the associated
setup screen (
FECG
or
US/US2
).
NOTE
FHR data is collected over time for analysis. Resetting an alert clears all data
from the monitor’s memory for both FHR1 and FHR2.
To reset an alert:
1. Access the setup screen associated with the alert—indicated by the flashing
FHR numerics. Select the mode title softkey (
FECG
or
US/US2
).
2. Highlight the Alert field. Whenever you display the setup screen, this field is set
to
On
.
3. Change the Alert field setting to
Reset
. (If you change the field to
Reset
by
mistake and wish to change it back, simply set it to
On
again.)
4. Once an alert is reset: audio and visual indications are removed; and the alert
parameters information clears.
NOTE
It is possible that the Spectra Alerts feature may generate the same alert
again.
False Pattern Recognition
The system may recognize accelerations as baseline.
Mode Switching
During dual FHR monitoring, the system may “confuse” the FHRs following mode
switches after delivery of the presenting twin.
To guard against mode changes prior to delivery of the presenting twin: Use US for
the presenting twin and US2 for the second twin. When switching to FECG for the
presenting twin, disconnect the
US
connector which is no longer in use.
If an alert is generated following delivery of the presenting twin, evaluate the tracing
to determine if there are any clinical factors contributing to the alert. If you feel the
alert was generated in error, change the Alert field on the associated setup screen to
Reset. Consider the following:
„ If you continue monitoring the second twin with US2, and you disconnect the
FECG transducer which is no longer in use: the US2 fetal heart rate now moves
to the primary display; and the FHR trend, which was bold, now prints using a
normal print density.
„
If you later switch to internal monitoring for the second twin and you
disconnect the US2 transducer which is no longer in use: the fetal heart rate for
the second twin displays as FECG in the primary heart rate area; and the FHR
trend continues to print using a normal print density.
