Spectra Alerts: Trend Screen
Trend Screen
Select the Trend softkey from the FHR Setup screen to display the FHR/UA trend
screen. (For dual fetal heart rate monitoring, you can access it from either mode’s
setup screen.) The Trend screen displays:
the alert level and message, if present;
the most recent 10 minutes of FHR and UA trend data—reflecting the paper
scale and chart speed settings; and
the current time.
The following Figure shows a sample Trend screen with dual FHR monitoring in
progress and a level one decelerations alert.
Trend Screen Example
Uterine Contraction Frequency
The Spectra Alerts option includes a uterine contraction (UC) frequency display.
When enabled, the UA screen:
provides the setup field for the UA display;
provides a uterine contraction audio indicator; and
provides a UC frequency histogram which graphs the contractions per 10
minutes over the most recent 100 minutes.
