US-1 tracks primary fetal ECG rates. US-2 tracks secondary fetal activity for either independent “normal or “twins simulation, US-2 rate fixed at 140 BPM
Fetal Patterns:
Note: US-1 fetal ECG track these selections. US-2 is in normal pattern, except during TREND #1 selection.
Variability selections (added to fetal ECG)
Absent variability, low variability, mild variability, high variability, severe variability, and long-tern variability
Note:
These patterns repeat and toco channel will perform toco wave selected
Optional mechanical fetal heart
Provides a mechanical interface to the ultrasound transducer; can be connected to either ultrasound channels. This option, due to its power consumption, requires an ac power adapter to be connected.
