4 results about "Time course" patented technology

A medical device has features for an alarm organization with regard to the time course of a minute volume. The alarm organization features are configured for undershoots (117, 217) and exceedances (118, 218) of a comparison minute volume (208) over a period of time (1000). The features make it possible to avoid overreacting to non-critical situations.
