Embodiment Construction

[0025] The present invention relates generally to measuring physiological parameters of a patient, and more particularly, to systems, methods and devices for measuring and deriving physiological parameters relative to various environmental parameters. In contrast to prior art systems and methods, the present invention utilizes one or more external computing devices to obtain ambient measurement values, and then the one or more external computing devices use the ambient values along with the measured physiologic parameters to calculate relative physiologic parameter values.

[0026] As discussed herein, the present invention relates to systems and methods for obtaining relative physiologic parameter values. The physiologic parameter values obtained can be any physiologic measurement, such as, blood pressure, temperature, blood or fluid flow, strain, electrical, chemical or magnetic properties within the body, or the like. As one skilled in the art will appreciate, the type of measureme...

Abstract

One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device (“IMD”) and an external computing device. The IMD is operable to determine an absolute physiologic parameter value within a patient's body, and communicate the absolute physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device is operable to receive the absolute physiologic parameter from the IMD and obtain an ambient condition value outside the body that can affect the absolute physiologic parameter value. The external computing device then calculates a relative physiologic parameter value from the ambient condition value and the absolute physiologic parameter value.
