Abstract
A method of determining a value of a physiological parameter for a subject at a selected state includes obtaining, via a device located a distance from the subject, a value of the physiological parameter of the subject at a particular time-of-day, and applying a time-dependent relationship function to the obtained physiological parameter value via a processor to determine a value of the physiological parameter at the selected state.
Claims21
A method of estimating a value of a physiological parameter for a subject at a selected metabolic state, the method comprising:
- obtaining, via a non-wearable device located at a stand-off distance from the subject, a value of the physiological parameter of the subiect at a time-of-day, wherein the non-wearable device comprises a sensor configured to measure heart rate, breathing rate, and/or physical activity of the subject, wherein the sensor is an electromagnetic energy sensor, an electrical energy sensor, a magnetic energy sensor, an inductive energy sensor, a capacitive energy sensor, a thermal energy sensor, or an acoustic energy sensor;
- and
- estimating the value of the physiological parameter for the subject at the selected metabolic state by applying a time-dependent relationship function to the obtained physiological parameter value via at least one processor, wherein the selected metabolic state is different from a current metabolic state of the subject.
A system, comprising:
- a non-wearable sensor configured to measure heart rate, breathing rate, and/or physical activity of a subject located at a stand-off distance from the non-wearable sensor, wherein the non-wearable sensor is an electromagnetic energy sensor, an electrical energy sensor, a magnetic energy sensor, an inductive energy sensor, a capacitive energy sensor, a thermal energy sensor, or an acoustic energy sensor;
- and
- at least one processor configured to obtain from the non-wearable sensor a value of a physiological parameter of the subject at a time-of-day, and to estimate a value of the physiological parameter for the subject at a selected metabolic state by applying a time-dependent relationship function to the obtained physiological parameter value, wherein the selected metabolic state is different from a current metabolic state of the subject.
