Abstract
The present disclosure is directed to systems and methods for providing optimal photoplethysmography (PPG) sensor placement instructions to a subject. As described, the systems and methods of the present disclosure minimizes the risk of low signal quality by ensuring proper device placement, supports patient autonomy by providing guided assistance, and reduces the number of wasted sensors due to improper placement.
Claims15
A method providing optimal photoplethysmography (PPG) sensor placement instructions to a user, comprising:
- providing a PPG placement system comprising a plurality of light sources and at least one light sensor, wherein each of the plurality of light sources is spaced relative to the other plurality of light sources:
- performing one or more iterations of:
- emitting light from each of the plurality of light sources, after the PPG placement system is placed on a first location on a surface of the subject's body;
- detecting, by the at least one light sensor, the emitted light:
- determining, by a processor of the PPG placement system, which one of the plurality of light sources is most optimally placed on the surface of the subject's body;
- and
- providing feedback to the user, via a user interface of the PPG placement system, to move the PPG placement system in the direction of the one of the plurality of light sources that is determined to be most optimally placed on the surface of the subject's body.
A method for providing optimal photoplethysmography (PPG) sensor placement instructions to a user, comprising:
- providing a PPG placement system comprising at least one light source and at least one light sensor:
- performing, at each of a plurality of different locations on a surface of the subject's body the steps of:
- (i) emitting light from the at least one light source;
- and (ii) detecting, by the at least one light sensor, the emitted light;
- determining, by a processor of the PPG placement system, which one of plurality of different locations on the surface of the subject's body is a most optimal placement of the PPG placement system for signal quality;
- and
- providing feedback to the user, via a user interface of the PPG placement system. regarding the most optimal placement of the PPG placement system.
A method for providing optimal photoplethysmography (PPG) sensor placement instructions to a user, comprising:
- providing a PPG placement system comprising at least one light source and a plurality of light sensors, wherein each of the plurality of light sensors is spaced relative to the other plurality of light sensors;
- performing one or more iterations of:
- emitting light from at least one light source, after the PPG placement system is placed on a first location on a surface of the subject's body:
- detecting, by one or more of the plurality of light sensors, the emitted light;
- determining, by a processor of the PPG placement system based on the detected emitted light, an optimal placement for a PPG sensor on the surface of the subject's body;
- and
- providing feedback to the user, via a user interface of the PPG placement system, to move the PPG placement system in the direction of the determined optimal placement on the surface of the subject's body.
