Systems and methods for dynamically identifying a patient support surface and patient monitoring

A patient monitoring system for monitoring a patient area, the system comprising:

• a processor;
• and
• a memory having executable instructions stored thereon that when executed by the processor cause the processor to:
• receive a plurality of frames from a camera, the plurality of frames including three dimensional pixel information of a patient area;
• identify a location of a patient support surface in each of the plurality of frames based on the three dimensional information;
• calculate a nominal patient support location based on an aggregate of the location of the patient support surface identified for each of the plurality of frames;
• set one or more thresholds above or below the patient support surface based on the nominal patient support location;
• identify locations of one or more features of a patient in each of the plurality of frames based on the three dimensional information;
• calculate a nominal patient location based on an aggregate of the locations of the one or more features of the patient identified for each of the plurality of frames;
• compare the nominal patient location to the one or more thresholds;
• and
• generate an indication with a user interface based on the nominal patient location traversing the one or more thresholds.

A method for processing a chronological series of frames containing three dimensional pixel information generated by a camera to monitor a patient in a patient area by performing the following steps, each step performed at least in part by a computing system:

• receiving a plurality of frames from the camera, the plurality of frames including three dimensional pixel information of the patient area;
• identifying a location of a patient support surface in each of the plurality of frames based on the three dimensional information;
• calculating a nominal patient support location based on an aggregate of the location of the patient support surface identified for each of the plurality of frames;
• setting one or more thresholds above or below the patient support surface based on the nominal patient support location;
• identifying locations of one or more features of a patient in each of the plurality of frames based on the three dimensional information;
• calculating a nominal patient location based on an aggregate of the locations of the one or more features of the patient identified for each of the plurality of frames;
• comparing the nominal patient location to the one or more thresholds;
• and
• generating an indication with a user interface based on the nominal patient location traversing the one or more thresholds.

• receive a plurality of frames from a camera, the plurality of frames including three dimensional pixel information of a patient area;
• identify a location of a patient support surface in each of the plurality of frames based on the three dimensional information;
• determine locations of body parts of a patient in each of the plurality of frames based on the three dimensional information;
• determine a given one of the body parts of the patient is beyond one or more thresholds above or below the patient support surface based on the determined locations;
• generate an indication with a user interface based on the determination of the given one of the body parts is beyond the one or more thresholds.
