Abstract
A method and an apparatus are provided for performing waveform analysis on physiological parameters. In one embodiment, a method includes reading measurement values of a first physiological parameter relating to time, and displaying them as a trend display graph in a trend display area that includes first coordinates representing time and second coordinates representing the measurement values. The method also includes acquiring a time selected in the trend display graph, and displaying, in a waveform display area, waveform data of a second physiological parameter associated with formation of the first physiological parameter during periods before and after the selected time. The waveform display area includes time coordinates. The disclosed embodiments allow medical staff to view the curve of a patient's physiological parameters throughout a monitoring/therapy period. Medical staff may make a detailed analysis of the waveform data in real time, which may provide a basis for making decisions in the following therapy processes.
