1. A method for monitoring an orientation of a person with respect to a defined turning protocol for the person, the method comprising:
- receiving, via an input device, user input defining a person-specific restricted orientation associated with an injury at a specific side or area of the person'"'"'s body, the person-specific restricted orientation comprising an orientation in which a patient support surface imparts pressure on the injured side or area of the person'"'"'s body,sensing, with a sensor device configured to be physically wearable by the person, information representative of a physical orientation of the person,executing, by a processor, computer instructions stored in non-transitory computer-readable media to;
determine, based on the sensed physical orientation of the person, a turn of or by the person from a first orientation to a second orientation,determine both;
(a) whether the second orientation to which the person has turned is the restricted orientation defined for the person via the input device, and(b) whether the second orientation to which the person has turned is compliant with the defined turning protocol for the person,initiate an audible or visual alert in response to each one of the following;
a determination that the second orientation to which the person has turned is the restricted orientation,a determination that the second orientation to which the person has turned is non-compliant with the defined turning protocol, anda determination that a time spent in the second orientation exceeds a threshold time specified by the defined turning protocol, andadjust a timer of the defined turning protocol without initiating an audible or visual alert in response to a determination that the second orientation to which the person has turned (a) is compliant with the defined turning protocol and (b) is not the restricted orientation, and is thus a compliant turn.

Abstract
A monitoring system and method tracks a patient'"'"'s position over time and ensures that proper turning or other manipulation is done within the time prescribed. Preferably, the techniques herein continuously monitor patient position and alert medical or other personnel of the need for turning or other patient manipulation. The system may be implemented within a medical or other care facility, or within a patient'"'"'s home.

11. A system for monitoring an orientation of a person, the system comprising:
-
an input device configured to receive user input defining a restricted orientation associated with an injury at a specific side or area of the person'"'"'s body, the person-specific restricted orientation comprising an orientation in which a patient support surface imparts pressure on the injured side or area of the person'"'"'s body, a sensor device configured to be physically wearable by the person and configured to output orientation information representative of changes in the orientation of the person with respect to the physical support surface, computer instructions stored in non-transitory computer-readable media, an audio or visual output device, and a processor in communication with the sensor device and the audio or visual output device, the processor configured to; receive the orientation information output by the sensor device, and execute the computer instructions to; determine, based on the received orientation information, a particular turn of the person from a first orientation to a second orientation, determine whether the second orientation to which the person has turned is the user-defined restricted orientation for the person defined by the received user input, determine whether the second orientation is a correct orientation for the person according to a defined turning protocol for the person, determine whether the particular turn from the first orientation to the second orientation is a compliant turn or a non-compliant turn based at least on (a) the determination of whether the second orientation is the user-defined restricted orientation for the person and (b) the determination of whether the second orientation is a correct orientation for the person according to the defined turning protocol for the person, and based on the determination of whether the particular turn is a compliant turn or a non-compliant turn; initiate an audible or visual non-compliant turn notification via the audio or visual output device if the particular turn is determined to be a non-compliant turn, and not initiate an audible or visual notification via the audio or visual output device if the particular turn is determined to be a compliant turn. - View Dependent Claims (12, 13, 14, 15, 16)
