Specifications
Fetal ECG |
Static Rates: |
|
30, 60, 90, 120, 150, 180, 210, |
|
and 240 BPM |
|
ECG Sensitivity: |
|
50 µV, 100 µV, 200 µV, 0.5 mV, 1 mV, and 2 mV |
|
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. |

Important Notes: |
|
US-1 tracks the fetal ECG rates. |
|
US-2 is the second ultrasound channel with a |
|
normal fetal ECG pattern. |
|
On the fetal and maternal ECG, the fetal ECG |
|
is 1/4 the size of the maternal ECG. |
|
The PS-320 turns on in the following state: |
|
• Fetal ECG static rate @ 150 BPM |
|
• US-1 tracks @ 150 BPM |
|
• US-2 normal pattern |
|
• Pressure sensitivity @ 5 µV/mmHg |
|
• Pressure/Toco set to zero |
|
• Maternal ECG rate @ 80 BPM |
|
• ECG sensitivity @ 1 mV |
|
• Toco wave is normal duration @ 0 to 50 divisions (i.e. 0 to 50 mmHg) |
