Abstract
An estimate of a functional capacity such as VO2Max is made by applying the vital signs of a monitored human to a trained encoding neural network producing a cardio profile vector. The vector is applied to a trained functional capacity (VO2Max) neural network to estimate the functional capacity. Once estimated, an action is taken.
Claims20
A system for treating and improving the cardiopulmonary health of humans, the system comprising:
- an encoding network configured to generate a cardio profile vector responsive to input of a duration of vital sign data;
- a functional capacity estimation network configured to generate an estimate of a cardiorespiratory functional capacity of a person based upon an input of a cardio profile vector generated for that person;
- and
- a control circuit
- wherein the encoding network is trained using an excluded-variable estimation network configured to receive as input a duration of vital sign data and a cardio profile vector, and generate an estimate of at least one vital sign excluded from the input,
- wherein the encoding network is trained to produce cardio profile vectors that are effective to enable the excluded-variable estimation network to make accurate estimates of the at least one vital sign excluded from input to the excluded-variable estimation network, by propagating excluded-variable estimation error as a cost function that is applied to and trains the encoding network;
- and wherein said control circuit is configured to receive a duration of monitored data from a sensor worn by a monitored human subject, apply the monitored data to the encoding network after being trained to produce a current cardio profile vector, apply the current cardio profile vector to the functional capacity estimation network after being trained to produce a current estimate of functional capacity of the monitored human subject;
- and
- based upon the current estimate of functional capacity, performing one or more actions selected from the group consisting of:
- the control circuit displays the current estimate in a time series with prior estimates to a clinician for review of possible health changes in the monitored human subject;
- the control circuit compares the current estimate to prior estimates and testing for a change whereupon an alert is triggered to a clinician to investigate the health of the monitored human subject;
- the control circuit compares the current estimate to prior estimates and testing for a change whereupon a questionnaire is sent to the monitored human subject;
- the control circuit compares the current estimate to prior estimates and testing for a change whereupon an entry is made in the medical record of the monitored human subject indicating a change in health of the monitored human subject occurred;
- the control circuit compares the current estimate to estimates from other monitored human subjects, in order to quantify health affects between at least a control group receiving a first intervention and a test group receiving a second intervention in a clinical trial;
- and
- the control circuit transmits an electronic control signal that controls the operation or setting a parameter of a medical device associated with treating or monitoring the monitored human subject.
