Abstract

Present embodiments are directed to a system and method capable of detecting and graphically indicating physiologic patterns in patient data. For example, present embodiments may include a monitoring system that includes a monitor capable of receiving input relating to patient physiological parameters and storing historical data related to the parameters. Additionally, the monitoring system may include a screen capable of displaying the historical data corresponding to the patient physiological parameters. Further, the monitoring system may include a pattern detection feature capable of analyzing the historical data to detect a physiologic pattern in a segment of the historical data and capable of initiating a graphical indication of the segment on the screen when the physiologic pattern is present in the segment.

Claims

a monitor capable of receiving input relating to patient physiological parameters and storing data related to the parameters, the monitor comprising;

a pattern detection feature capable of analyzing the data to detect a pattern in the data; and

a graphical indicator capable of being displayed comprising a graphical representation based at least in part on one or more of an occurrence, frequency, or magnitude of the pattern.

2. The system of claim 1, wherein data related to the parameters comprises pulse oximtery data,

3. The system of claim 1, wherein the pattern comprises an oxygen desaturation pattern indicative of ventilatory instability.

4. The system of claim 1, wherein the graphical indicator comprises an indicator that changes in relation to an occurrence, frequency, or magnitude of the pattern.

5. The system of claim 1, wherein the graphical indicator comprises a geometric shape and wherein the geometric shape is filled in relation to one or more of an occurrence, frequency, or magnitude of the pattern.
