Abstract

A graphical user interface is provided displaying a first viewing window selected from a set of possible viewing windows conveying respective feature measurements related to labor progression. At least one viewing window in the set of possible viewing windows conveys a given feature measurement and a safety limit associated to the given feature measurement. The graphical user interface also displays at least one control allowing a user to select a subset of viewing windows from the set of possible viewing windows, the subset of viewing windows including at least one viewing window other than the first viewing window. The selected subset of viewing windows is displayed simultaneously with the first viewing window. In response to the given feature measurement exceeding the associated safety limit, information is displayed to attract the attention of the user to the viewing window conveying the given feature measurement.
