Spectra Alerts: Uterine Contraction Frequency
UC Frequency Histogram
If the Spectra Alerts option is enabled, the UA Setup screen displays a UC
Frequency Histogram as shown in the next Figure. Each bar in the graph represents
the number of contractions in a 10-minute segment. The graph displays up to 10 bars
(or 100 minutes).
UC Frequency Histogram
The following two messages may display above the UC Frequency Histogram:
RECORDING UA?
and
UA BASELINE SET?
For more information, refer to Table on
pages C-17 through C-21.
Enabling/Disabling UC Chime
If the Spectra Alerts option is enabled, the UA Setup screen contains a
UC Chime
field. When enabled: a low -frequency chime sounds at the onset of a contraction; a
high -frequency chime sounds at the conclusion . This audio contraction indicator is
useful to caregivers as well as patients. Caregivers are made aware of contractions
during internal exams or while making adjustments to internal sensors/transducers
without having to watch the monitor. An anesthetized mother can use the indicator
as a “push signal” if she is unable to feel contractions.
To enable/disable the
UC Chime:
1. Access the UA setup screen by selecting the UA mode title (
TOCO
or
IUP
).
2. Set the
UC Chime
field to the desired setting:
On
or
Off
. Refer to the Figure, “UC
Frequency Histogram”.
