Figure 14. Fetal ECG Screen
Push the softkey labeled Back to go back to the Special Functions screen.
To change the fetal heart rate:
1. Push  or  to highlight the Fetal HR value.
2. Push .
3. Push  or  to change the heart rate value in 1 bpm steps between 60 and 240 bpm.
Note
When you hold down the direction key, the step size will change to 10 bpm
until the key is released.
4. Push  to set the heart rate and go back to the Fetal ECG screen.
To change the amplitude of the fetal waveform:
1. Push  or  to highlight the Amplitude value.
2. Push  or  to adjust the amplitude. Each push of a key increases or decreases the
amplitude in the direction of the key pushed. The Product simulates a fetal heart
signal amplitude of 0.05 to 0.25 mV by 0.05 mV intervals and 0.50 to 5.00 mV that is
set in 0.25 mV intervals.
3. Push  to set the amplitude and go back to the Fetal ECG screen.
How to Simulate Intrauterine Pressure (IUP)
The simulated intrauterine-pressure (IUP) waveform shows a measurement read by an
intra-amniotic catheter connected to a pressure transducer. The Product simulates the IUP
on IBP channel 1, with a 5 or 40 μ V/V/mmHg sensitivity (as has been setup for blood
pressure).
The Product sends waveforms to simulate intrauterine pressure during a contraction of
the uterus in childbirth. Each IUP wave goes for 90 seconds with a bellshaped pressure
curve that increases from zero to 90 mmHg and goes back to zero. In an IUP-wave
simulation, the fetal heart rate (which always begins at 140 BPM, regardless of the fetal
ECG rate.) changes with the blood pressure. The fetal heart rate and blood pressure
shows in the display.
The IUP period is adjustable to four preconfigured values: a manually started contraction,
and contractions that start at 2, 3, or 5 minute intervals.
To do an Intrauterine pressure simulation, connect the fetal monitor to the Product as
shown in Figure 15.
