Filed:

Appl. No.:

11/498410

Inventors:

Apurv Kamath - Solana Beach CA, US
James Brauker - San Diego CA, US
Aarthi Mahalingam - San Diego CA, US
Ying Li - San Diego CA, US

International Classification:

A61B 5/00

US Classification:

600300000

Abstract:

Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as interfering species, ischemia, pH changes, temperatures changes, known or unknown sources of mechanical, electrical and/or biochemical noise, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system processes some or the entire data stream continually or intermittently based at least in part on whether the signal artifact event has occurred.
