Systems and methods for vital sign monitors are disclosed herein. In some cases, a warning score is calculated based on first measurements of a first biological condition and second measurements of a second biological condition. In particular cases, the first measurements and the second measurements are automatically measured during the same time period. The warning score may be calculated based on an average of the first measurements and an average of the second measurements. Based on determining that the warning score is outside of a predetermined range, a clinical device may output an alert.

A pressure support system for providing pressure support therapy to a patient, the pressure support device includes an airflow generator structured to generate a flow of breathing gas to the patient, a temperature conditioning unit structured to adjust a temperature of the breathing gas provided to the patient, and a processing unit structured to estimate a core body temperature of the patient for selected times of day based on one or more inputs and to control the temperature conditioning unit to adjust temperature of the breathing provided to the patient at the selected times of day based on the estimated core body temperatures of the patient.

A lighting system for establishing a database of multispectral circadian rhythm lighting scenario and psychological stress indicators is configured in space, which is characterized by downloading the multispectral circadian rhythm lighting scenario database from the cloud; the multispectral lighting parameters and circadian rhythm parameters are selected from the multispectral circadian rhythm lighting scenario database to start the light-emitting device for lighting; the ambient light sensor measures and judges whether the circadian rhythm parameters reach the set value; when each circadian rhythm parameter in the circadian rhythm lighting scenario database has reached the set value, the light-emitting device is started for lighting; after the blood or saliva of the light control subjects were tested, the psychological stress index values of the illuminators were obtained; the portable communication device transmits the circadian rhythm parameters and psychological stress index values to the cloud; among them, the circadian rhythm parameters include: circadian rhythm lighting parameters and circadian rhythm scenario parameters.

A wheel chart for visualizing sleep pressure on a person's body by manipulating a series of moveable circular disks positioned on a common axis wherein the wheel includes a first disk representing a circadian (C) process and second disk representing a homeostatic (S) process. The disks are rotatable relative to each other to simulate how the C and S processes increase and decrease sleep pressure.

Circadian health recommendations and/or automation instructions and spectral data on which they are based can be provided to a user through a mobile device that lacks a spectral sensor. A user mobile device lacking a spectral data uploads place and time data to a cloud-based circadian health system. A light-exposure model of the circadian health system estimates spectral data values based on the place and time data. The light-exposure model’s estimation can be based on data received by the circadian health system based on user devices equipped with spectral sensors and from other sources. A relatively small number of mobile user devices (with spectral sensors) can thus provide for spectral value estimates for a relatively large population of mobile user devices that lack spectral sensors—greatly expanding the range and number of people that benefit from improved circadian health.

According to certain embodiments, an electronic device comprises: a sensor module; a processor operatively connected to the sensor module; and a memory operatively connected to the processor, wherein the memory stores instructions that, when executed, cause the processor to perform a plurality of operations comprising: acquiring sensor information through the sensor module, determining sleep information of a user, based on the sensor information, and determining a biorhythm of the user, based on the sleep information.

A method for heart failure management may include volume overload intervention in response to sensor-based parameters indicating volume overload. The method may include administering non-volume overload intervention in response to the sensor-based parameters not indicating volume overload. Volume overload may be determined based on monitoring sensor-based parameters. Sensor-based parameters may be monitored in response to receiving an alert indicative of a worsening heart failure score or status for a patient.
