Bidirectional physiological information display
First Claim
1. A method of displaying physiological information on a physiological monitor configured to be coupled to a patient sensor operative to detect a physiological signal, the method comprising:
- by a processor;
receiving a respiration signal from an acoustic respiratory sensor coupled with a patient;
outputting a value indicator to a display of the physiological monitor, the value indicator configured to represent an envelope amplitude of the respiration signal;
expanding the value indicator in two directions simultaneously in response to increasing values of the envelope amplitude of the respiration signal wherein the value indicator is configured to expand from a reference position representative of a transition between inspiration and expiration in the respiration signal;
contracting the value indicator opposite the two directions simultaneously in response to falling values of the envelope amplitude of the respiration signal; and
changing a characteristic of the value indicator to visually distinguish between inspiration and respiration.

Abstract
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.

8. A method of displaying physiological information on a physiological monitor, the method comprising:
by a processor; receiving a respiration signal from a sensor coupled to a patient; activating a visual indicator of a visual element, the visual indicator configured to represent an amplitude of the respiration signal; and illuminating the visual indicator outwards from a reference position toward both a first end region and a second end region of the visual element and then inwards from the first and second end regions toward the reference position, responsive to changes in the amplitude of the respiration signal, wherein the reference position is representative of a transition between inspiration and expiration, and wherein the visual indicator is configured to have a first visual appearance corresponding to inspiration and a second visual appearance corresponding to expiration. - View Dependent Claims (9, 10, 11)

12. A physiological monitor comprising:
-
a processor configured to receive physiological information comprising a respiration waveform from one or more sensors coupled with a patient; and a display comprising a visual element for representing values of an amplitude of the respiration waveform, the visual element comprising; a middle portion representing an reference position, wherein the reference position is representative of a transition between inspiration and expiration, 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, and a value indicator, wherein the processor is configured to illuminate the value indicator starting from the reference position and expanding both to the first and second extremity portions, followed by contracting the value indicator at least partway toward the reference position, responsive to changes in the amplitude of the respiration waveform, and wherein the value indicator is configured to have a first visual appearance corresponding to inspiration and a second visual appearance corresponding to expiration. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
