What is it?
When monitoring dual heart rates using US/US2 or FECG/US, overlapping traces
may be difficult to interpret. All 120 Series Monitors provide a +20 BPM shift for
the secondary fetal heart rate trend to alleviate this problem. When using US/US2 or
FECG/US2, and the US2 trace is shifted +20 BPM, the symbol prints on
the upper portion of the top grid every 4.5 cm. When using US/FECG, and the US
trace is shifted +20 BPM, the symbol prints on the upper portion of the top
grid every 4.5 cm. In both cases, an arrow (→) and a vertical dashed line are printed
to draw attention to the start of the shifted trend.
10 Min
The heart rate offset mode is enabled with an auto-revert feature. If the trace is
shifted by the user, the heart rate will revert back to the normal (unshifted) level
after 10 minutes.
On
The heart rate offset mode is enabled. If the user shifts a trace, the trace will remain
shifted until the user manually sets the trace back to normal (unshifted level).
Off
The heart rate offset mode is disabled. The user cannot shift traces.
NOTE: Refer to the operator’s manual for information about activating the heart
rate offset mode.
Default TOCO Reference
This field sets the default uterine activity pressure reference for the tocotransducer.
Use the Trim Knob control to cycle through the available settings: 5, 10, 15, 20, or
25 relative units. (The factory default setting is 10 relative units.)
When using a tocotransducer, momentary depression of the
UA Reference button
sets the pressure baseline at the default setting.
Pressing the
UA Reference button for more than two seconds causes the UA
reference value to override the default setting and cycle through all available
selections: 5, 10, 15, 20, or 25 relative units, starting at the default setting until the
button is released. This value is stored as the new baseline for the currently
measured uterine activity signal; as soon as the
UA Reference button is
momentarily pressed, the baseline returns to the default value.
FM Remote Mark
This field configures the marker annotation that is printed on the strip chart paper
whenever a patient presses the button on the Remote Marker accessory. Use the
Trim Knob control to alternate between ON and OFF. The factory default setting is
OFF.
The annotation is commonly used to record an “event”; while the annotation
is commonly used as an indication that the mother has perceived fetal movement.
