Figure 4-21. medSim 300B Simulated Late Deceleration
ldec: Late deceleration. Fetal heart rate change begins when intrauterine pressure is at
its peak (lags intrauterine pressure change by 45 seconds). Fetal heart rate starts
at 140 BPM, slows to 100 BPM, and returns to 140 BPM.

uacc: Uniform acceleration. Fetal heart rate change lags intrauterine pressure change
by 30 seconds. Fetal heart rate starts at 140 BPM, increases to 175 BPM, and
returns to 140 BPM.
off: Removes fetal heart rate from the maternal ECG.
