Signal loss

The system monitors the loss of fetal heart rate signal. Where there is a gap in the
trace due to signal loss, the analysis, interpolates a straight line through the missing
section when fitting the baseline.

If signal loss is greater than 50%, the analysis will not be able to calculate the
parameter values. The signal loss also affects the reliability of the baseline fit.
