1. A physiological characteristic monitor, comprising:
- an input device capable of receiving a signal from a sensor, the signal being based on a sensed physiological characteristic value of a user; and
a processor for analyzing the received signal;
wherein the processor determines a dynamic behavior of the physiological characteristic value;
wherein the processor provides an observable indicator based upon the dynamic behavior of the physiological characteristic value so determined;
wherein analyzing the received signal and determining a dynamic behavior includes repeatedly measuring the physiological characteristic value to obtain a series of physiological characteristic values and analyzing a rate of change of the physiological characteristic value over time from the series of physiological characteristic values;
wherein analyzing the received signal comprises determining whether a most recent of the series of physiological characteristic values is within a qualifying range; and
wherein a slope of a line fit to the series of physiological characteristic values is calculated if the most recent of the series of physiological characteristic values is within the qualifying range.

Abstract
Apparatuses and methods for medical monitoring physiological characteristics values such as blood glucose levels for the treatment of diabetes, are presented. The apparatuses and methods provide dynamic glucose monitoring functions that perform predictive analysis to anticipate harmful conditions, such as glucose crash and hyperglycemic incidents for a patient. The dynamic functions can also be used to maximize athletic performance and warn of inadequate nocturnal basal rate. Other aspects include advanced alarm and reminder functions, as well as advanced data presentation tools to further facilitate convenient and efficient management of various physiological conditions.
