Bidirectional physiological information display
View Patent ↗A patient monitor for displaying a physiological signal can include a visual element having a middle portion indicative of a transition in the physiological signal between physiological states. The visual element can also include first and second extremity portions, the first extremity portion extending from the middle portion in a first direction and the second extremity portion extending from the middle portion in a second direction. The visual element can also include an actionable value indicator to specify a value about the middle portion and the first and second extremity portions. The patient monitor can also include a processor configured to cause the value indicator to actuate in both the first and second directions according to changes in the physiological signal.
1. A system comprising:
one or more respiratory sensors configured to be coupled with a patient and to generate a respiration waveform representing inspiration and expiration cycles of the patient;

compare the peak value to the goal value.
4. The system of claim 3 , wherein the processor is configured to, in response to determining that the peak value exceeds the goal value, output an acknowledgement that the goal value has been reached.
5. The system of claim 4 , wherein the acknowledgement comprises an audible sound.
6. The system of claim 4 , wherein the acknowledgement comprises a change in appearance to one or both of the first and second goal indicators.
7. The system of claim 3 , wherein the processor is configured to, in response to determining that the peak value does not equal or exceed the goal value, expand the value indicator toward the first and second goal indicators.
8. The system of claim 1 , wherein the visual element comprises a bar graph, and wherein the first and second goal indicators each comprise a segment of the bar graph.
9. The system of claim 1 , wherein the processor is configured to illuminate the first and second goal indicators using a different color than that used for the value indicator.
