Figure 16. Intrauterine Pressure Contractions Screen
How to Set the Fetal Heart Rate Response
The Product simulates three types of preconfigured waveforms for a periodic fetal heart
rate that is interactive with uterine contractions: early deceleration; late deceleration; or
acceleration:
With early deceleration, the fetal heart rate follows the intrauterine pressure (no lag). The
fetal heart rate starts at 140 BPM, slows to 100 BPM at intrauterine-pressure peak, and
then goes back to 140 BPM as the IUP falls back to zero.
With late deceleration, the change in fetal heart rate starts when IUP pressure is at its
peak and lags the change in intrauterine pressure by 45 seconds. The fetal heart rate starts
at 140 BPM, slows to 100 BPM, and then goes back to 140 BPM.
With acceleration, the change in fetal heart rate lags the change in intrauterine pressure
by 30 seconds. The fetal heart rate starts at 140 BPM, increases to 175 BPM, and then
goes back 140 BPM.
To set the fetal heart rate response:
1. Push  or  to highlight the HR Response value.
2. Push .
3. Push  or  to highlight Early Deceleration, Late Deceleration, or
Acceleration.
4. Push  to set the response value and go back to the Fetal ECG: IUP screen.
How to Set the Intrauterine Contraction Simulation
The IUP (Intrauterine Pressure) period is adjustable to four preconfigured values. These
are contractions that start manually or at 2, 3, or 5 minute intervals.
To set the contractions:
1. Push  or  to highlight the Contraction value.
2. Push .
3. Push  or  to highlight Manual Start, 2, 3, or 5 minutes.
4. Push  to set the contraction value and go back to the Fetal ECG: IUP screen.
5. To start a contraction, push the Start softkey. The screen below shows in the display
and updates with real-time simulation data. The time until the contraction ends is also
shown in the display. See Figure 17.
