Physiological monitoring system

A portable physiological monitoring system comprising:

• an optical sensor configured to output one or more signals responsive to light from a light source attenuated by tissue of the user at a measurement site, said one or more signals responsive to an oxygen saturation (“SpO2”) of said tissue;
• and
• a processing board in data communication with the optical sensor and a mobile computing device including a display and cellular communication, wherein the processing board is configured to:
• receive said one or more signals from the optical sensor;
• process said one or more signals to generate one or more SpO2 measurement values;
• and
• transmit the one or more SpO2 measurement values to the mobile computing device;
• wherein, one or more hardware processors of the mobile computing device are configured to execute an application, the application configured to execute commands to:
• generate a graphical user interface having a plurality of display portions;
• display, in at least one of the plurality of display portions, a representation based on the one or more SpO2 measurement values generated by the processing board;
• and
• display, in a different one of the plurality of display portions, a plurality of user inputs configured to allow the user to interact with at least one of the plurality of display portions or the application;
• and
• wherein the processing of said one or more signals to generate said one or more SpO2 measurement values is performed only on the processing board, thereby freeing up memory available to the mobile computing device.

A portable physiological monitoring system comprising:

• an optical sensor configured to emit light at one or more wavelengths and detect at least a portion of the emitted light after attenuation through tissue of a user at a measurement site on the user's body, said optical sensor further configured to output one or more signals responsive to the detected light;
• and
• a processing module housing comprising a processing board configured to:
• receive said one or more signals from the optical sensor;
• process said one or more signals to determine one or more physiological parameters of the user;
• and
• transmit the determined one or more physiological parameters over a wireless transmission protocol to a mobile computing device, wherein the optical sensor is configured to receive power from the processing module housing.

A method of monitoring one or more physiological parameters of a user, the method comprising:

• emitting, from an optical sensor of a physiological monitoring system, light of one or more wavelengths toward tissue of the user at a measurement site on the user's body;
• detecting, with the optical sensor, at least a portion of the emitted light after the at least the portion of the emitted light passes through the tissue of the user at the measurement site;
• outputting, with the optical sensor, one or more signals responsive to the detected light;
• and
• receiving, with a processing board of the physiological measurement system, said one or more signals responsive to said detected light from the optical sensor;
• processing, with the processing board, said one or more signals to determine one or more physiological parameters of the user;
• and
• transmitting the one or more physiological parameters to a mobile computing device, the mobile computing device including an application configured to generate a graphical user interface having a plurality of display portions, at least one of the plurality of display portions comprising a representation of the one or more physiological parameters and at least another one of the plurality of display portions comprising a plurality of user inputs configured to allow the user to interact with at least one of the plurality of display portions or the application.
