1. A pulse oximetry user interface comprising:
- a display;
a plurality of views each configured to occupy said display, each of said views adapted to present data responsive to a physiological signal;
a plurality of icons configured to occupy a portion of said views and adapted to designate the content of said views;
a plurality of keys proximate to said display and corresponding to said icons so as to select said icons;
a scale associated with said pulse waveform;
a signal strength measure corresponding to said physiological signal; and
a relationship between said signal strength and said scale so that said pulse waveform conveys information regarding said signal strengths, wherein one of said views presents a pulse waveform, another of said views presents a trend graph, and at least one of said icons can be selected so as to switch said display between said one view and another view.

Abstract
A pulse oximetry user interface has a display and a plurality of views each configured to occupy the display. Each of the views are adapted to present data responsive to a physiological signal. A plurality of icons are configured to occupy a portion of the views and adapted to designate the content of the views. Further, a plurality of keys are proximate to the display and correspond to the icons so as to select the icons. One of the views is a pleth view that presents a pulse waveform. Another one of the views is a trend view that presents a trend graph. At least one of the icons can be selected so as to switch the display between the pleth view and the trend view.
