1. A patient self-care management system, comprising:
a patient monitoring system that emits a signal containing data representing a status of a monitored medical condition of a patient, the patient monitoring system comprising at least one patient-implanted wireless sensor configured to measure a physiological parameter associated with the monitored medical condition as an input to said data, said at least one patient-implanted wireless sensor comprising an inferior vena cava (IVC) dimension sensor and said data comprises data representative of patient fluid volume, heart rate and respiration rate; and
a processing system configured to receive said data representing the status of the monitored medical condition and patient-specific information, wherein the processing system—
(a) accesses (i) at least one of a diagnostic or treatment algorithm related to the monitored medical condition, and (ii) at least one threshold or limit with respect to the monitored medical condition;
(b) generates patient-directed notifications using the diagnostic or treatment algorithm at least in part in response to the data generated by the IVC dimension sensor indicating patient fluid volume within a normal range defined as a portion of a euvolemic range of fluid state for the patient, said patient-directed notifications including instructions for patient self-care actions responsive to the status of the monitored medical condition of the patient;
(c) provides the patient-directed notifications for receipt by the patient through a patient personal device user interface;
(d) generates care-provider-directed notifications when the threshold or limit with respect to the monitored medical condition is determined to be exceeded or met, wherein the threshold or limit comprises at least one of a hypovolemic warning zone at a hypovolemic end within the patient euvolemic range and a hypervolemic warning zone at a hypervolemic end within the patient euvolemic range; and
(e) transmits the care-provider-directed notifications for receipt by a care provider through a care provider device.
