Abstract
According to some embodiments of the present invention, a display is used to show a signal from a physiological sensor as well as an indication of the signal's quality. While this indication of the signal's quality may be provided in a number of ways, it is preferably provided by changing a color on the display.
Claims24
A method of providing a caregiver with a visual evaluation tool helpful in determining an indication of signal quality, the method comprising:
- acquiring a signal from a physiological sensor capable of detecting light attenuated by body tissue carrying blood;
- measuring a signal quality of said signal;
- generating a trace responsive to said signal on a display;
- and
- varying a color of said trace so as to indicate said signal quality.
A method of altering display elements indicative of one or more parameters monitored by a patient monitoring device, the method comprising:
- acquiring a signal from a physiological sensor;
- generating display elements, including a plethysmograph trace, in response to said signal;
- calculating a signal quality;
- and
- altering a color of at least one of the display elements in response to the signal quality.
A physiological monitoring device that provides a visual indication of signal quality, the device comprising:
- a light sensitive detector capable of detecting light attenuated by body tissue carrying blood;
- a display having a trace;
- and
- a microprocessor configured to receive a signal from the light sensitive detector and generate the trace on the display in response to said signal, said microprocessor also configured to measure a signal quality of the signal and vary a color of the trace so as to indicate the signal quality.
