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.
Claims18
A method of displaying physiological information, the method comprising:
- by a processor:
- providing a value of a physiological parameter to a display of a patient monitor, the physiological parameter value reflecting physiological information obtained from a physiological sensor coupled to a patient;
- calculating a freshness of the physiological parameter value;
- adjusting an output associated with the parameter value based at least in part on the calculated freshness;
- setting the value of the physiological parameter to a minimum value in response to a predetermined freshness period elapsing;
- and
- providing functionality on a display of the patient monitor for a clinician to adjust the predetermined freshness period.
A method of displaying physiological information, the method comprising:
- by a processor:
- outputting a value of a physiological parameter to a display of a patient monitor, the physiological parameter value reflecting physiological information obtained from a physiological sensor coupled to a patient;
- outputting a signal quality indicator reflecting a quality of the physiological information obtained from the physiological sensor;
- determining whether the value of the physiological parameter is valid;
- adjusting the signal quality indicator responsive to said determination;
- setting the value of the physiological parameter to a reduced value in response to a predetermined freshness period elapsing;
- and
- providing functionality on a display of the patient monitor for a clinician to adjust the predetermined freshness period.
A method of displaying physiological information, the method comprising:
- by a processor:
- providing a value of a physiological parameter to a display of a patient monitor, the physiological parameter value reflecting physiological information obtained from a physiological sensor coupled to a patient;
- determining whether the value of the physiological parameter is valid;
- freezing an output associated with the physiological parameter value;
- calculating a freshness of the physiological parameter value, in response to said freezing;
- adjusting the output associated with the parameter value based at least in part on the calculated freshness;
- changing the output of the physiological parameter in response to a predetermined freshness period elapsing;
- and
- providing functionality on a display of the patient monitor for a clinician to adjust the predetermined freshness period.
