Waveforms: Waveform Area
The waveform area displays approximately 4 seconds of waveform data from one of
the following: FECG, MECG, or MSpO
independent of any of the numerics shown on the display.
For example: MSpO
can be chosen as the maternal pulse rate source (numerics)

while the MECG waveform is selected for display in the waveform area.
CAUTION
WAVEFORM INTERPRETATION—Waveforms generated by
the 250cx Series Monitor are not intended for true diagnostic
interpretation.
Use the Waveform softkey on the normal operating screen to select FECG, MECG,
MSpO2, or Off. (Refer to Figure on page 14-4.)
All waveforms are displayed at a rate of 25mm/sec. This speed is not adjustable. The
speed is displayed at the top right of the waveform.
The size is printed in the upper right above the waveform. This label is also a softkey
which can be used to change the setting. Select from the following: 0.25x (4 mV/cm),
0.5x (2.0 mV/cm), 1x (1.0 mV/cm), 2x (0.5 mV/cm), 4x (0.25 mV/cm), or Auto.
The selected lead is displayed in the upper right above the waveform. This label is
also a softkey which can be used to change the setting. Select from the following: I,
II, or III.
NOTE: The MECG lead can also be changed from the MHR/P Setup screen.
When the MECG Pacer option is enabled (On), the letter P is displayed prior to the
waveform speed. See Figure on page 7-6.
