Three-dimensional waveform display for a breathing assistance system

Logic instructions encoded in computer-readable media and when executed by a processor, operable to:

• receive signals from one or more sensors over a plurality of time periods;
• generate multiple instances of a waveform based on the received signals, each instance corresponding to one of the plurality of time periods;
• and
• cause the display of a graphical three-dimensional representation of the waveform over time, the three-dimensional representation including graphical representations of the multiple instances of the waveform displayed simultaneously.

A breathing assistance device configured to display a three-dimensional representation of a waveform over time, comprising:

• processing means for generating waveforms, the processing means configured to:
• receive signals from one or more sensors over a plurality of time periods;
• generate multiple instances of a waveform based on the received signals, each instance corresponding to one of the plurality of time periods;
• and
• display means for cooperating with the processing means to display a graphical three-dimensional representation of the waveform over time, the three-dimensional representation including graphical representations of the multiple instances of the waveform displayed simultaneously.
