Bidirectional physiological information display
First Claim
1. A method of displaying physiological information on a physiological monitor, the method comprising:
- by a processor;
receiving an acoustic respiration signal from an acoustic respiratory sensor coupled with a patient;
outputting a value indicator to a display of the physiological monitor to visually communicate one or more characteristics associated with the acoustic respiration signal to an observer, the value indicator configured to represent an envelope amplitude of the respiration signal and respiratory signal quality, wherein the value indicator includes a reference position representative of a transition between alternating phases of inspiration and expiration in the respiration signal;
expanding the value indicator from the reference position in two directions simultaneously in response to increasing values of the envelope amplitude during each alternating phase of inspiration and expiration;
contracting the value indicator opposite the two directions simultaneously toward the reference position in response to falling values of the envelope amplitude during each alternating phase of inspiration and expiration;
calculating a measure of the respiratory signal quality by analyzing the acoustic respiration signal; and
setting a characteristic of the value indicator to reflect the measure of the respiratory signal quality.

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.

14. A physiological monitor comprising:
-
a processor configured to receive physiological information comprising a respiration signal from one or more sensors coupled with a patient; and a display comprising a visual element configured to represent an envelope amplitude of the respiration signal and a respiratory signal quality of the respiration signal, the visual element comprising a value indicator, wherein the value indicator includes a reference position representative of a transition between alternating phases of inspiration and expiration in the respiration signal; wherein the processor is configured to; expand the value indicator from the reference position in two directions simultaneously in response to increasing values of the envelope amplitude during each alternating phase of inspiration and expiration; contract the value indicator opposite the two directions simultaneously toward the reference position in response to falling values of the envelope amplitude during each alternating phase of inspiration and expiration, calculate a measure of the respiratory signal quality, and change a characteristic of the value indicator to reflect the measure of the respiratory signal quality. - View Dependent Claims (15, 16, 17, 18, 19, 20)
