The one or more hardware processors can maintain a plurality of timers associated with available orientations of the patient. Each of the plurality of timers can account for a non-consecutive duration said patient is in an associated available orientation. The non-consecutive duration can vary depending on whether a patient is in the available orientation. The patient monitor can include a structured display including an orientation trend and a patient representation illustrating a current orientation of the patient. The orientation trend can include a heat map that graphically illustrates said non-consecutive durations of the patient in the available orientations and/or an orientation graph that displays the patient' orientation history. ## Claims ### Claim 1 A system for monitoring an orientation of a patient, the system comprising: one or more hardware processors configured to: receive one or more signals from a sensor attached to the patient; process said one or more signals to determine the patient's orientation; generate a graphic for display on a display of a patient monitor, the graphic comprising a plurality of lines, each line of the plurality of lines being associated with an orientation of a plurality of orientations assumable by the patient, each line of the plurality of lines having a same thickness, wherein the plurality of lines are uniformly spaced within the graphic at fixed positions relative to each other to spatially correspond to the orientations of the plurality of orientations, wherein one of said plurality of lines is associated with a supine orientation of the plurality of orientations and is positioned in a middle of the plurality of lines extending vertically from a bottom of the graphic to a top of the graphic; and modify an appearance of the plurality of lines based upon an amount of time the patient has been oriented in respective orientations of the plurality of orientations. ### Claim 2 (depends on 1) The system of claim 1, wherein the one or more hardware processors are further configured to generate a 3D representation of a model body corresponding to the patient for display adjacent to the graphic. ### Claim 3 (depends on 1) The system of claim 1, wherein the one or more hardware processors are further configured to: cause the plurality of lines to have a first color in response to determining that the patient has been oriented in an orientation associated with the plurality of lines for less than a first threshold; and cause the plurality of lines to have a second color in response to determining that the patient has been oriented in an orientation associated with the plurality of lines for less than a second threshold and for more than the first threshold; and cause the plurality of lines to have a first color in response to determining that the patient has been oriented in an orientation associated with the plurality of lines for more than the second threshold. ### Claim 4 (depends on 1) The system of claim 1, wherein the one or more hardware processors are further configured to generate an alert in response to determining that the patient has been oriented in an orientation for more than a threshold. ### Claim 5 (depends on 1) The system of claim 1, wherein the graphic further comprises a border, wherein the border comprises a first edge, a second edge opposite the first edge, a third edge, and a fourth edge opposite the third edge, each of the third and fourth edges connected to the first and second edges, and wherein said plurality of lines extend between the first and second edges. ### Claim 6 (depends on 1) The system of claim 1, wherein the one or more hardware processors are further configured to generate an indicator for display located adjacent to the graphic and configured to indicate a current orientation of the patient, wherein the one or more hardware processors are further configured to move the indicator as the current orientation of the patient changes. ### Claim 7 (depends on 1) The system of claim 1, wherein the sensor includes at least one or more of an accelerometer or gyroscope. ### Claim 8 (depends on 1) The system of claim 1, wherein the one or more hardware processors are further configured to generate for display a hatched pattern within the graphic, the hatched pattern representing an un-allowed patient orientation. ### Claim 9 (depends on 8) The system of claim 8, wherein the one or more hardware processors are further configured to generate an alert in response to determining that an orientation of the patient corresponds to the un-allowed patient orientation. ### Claim 10 (depends on 8) The system of claim 8, wherein the un-allowed patient orientation is pre-determined by a caregiver. ### Claim 11 A computing system comprising: a computer readable storage medium having program instructions embodied therewith; and one or more processors configured to execute the program instructions to cause the computing system to: receive one or more signals from a sensor attached to a patient; process said one or more signals to determine the patient's orientation;

and modify an appearance of the plurality of lines based upon an amount of time the patient has been oriented in respective orientations of the plurality of orientations. ### Claim 12 (depends on 11) The computing system of claim 11, wherein the user interface further comprises an indicator located adjacent to the graphic and configured to indicate a current orientation of the patient, wherein the one or more hardware processors are further configured to move the indicator as the current orientation of the patient changes. ### Claim 13 (depends on 11) The computing system of claim 11, wherein the user interface further comprises a 3D representation of a model body to the patient for display adjacent to the graphic. ### Claim 14 (depends on 11) The computing system of claim 11, wherein the one or more hardware processors are further configured to: display a hatched pattern within the graphic, the hatched pattern representing an un-allowed patient orientation; and generate an alert in response to determining that an orientation of the patient corresponds to the un-allowed patient orientation. ### Claim 15 (depends on 14) The computing system of claim 14, wherein the un-allowed patient orientation is pre-determined by a caregiver. ### Claim 16 A computer-implemented method comprising: receiving one or more signals from a sensor attached to a patient; processing said one or more signals to determine the patient's orientation; generating user interface data for rendering an interactive graphical user interface, the user interface comprising a graphic comprising a plurality of lines, each line of the plurality of lines being associated with an orientation of a plurality of orientations assumable by the patient, each line of the plurality of lines having a same thickness, wherein the plurality of lines are uniformly spaced within the graphic at fixed positions relative to each other to spatially correspond to the orientations of the plurality of orientations, wherein one of said plurality of lines is associated with a supine orientation of the plurality of orientations and is positioned in a middle of the plurality of lines extending vertically from a bottom of the graphic to a top of the graphic;
