Nerve-Express is a fully automatic, non-invasive computer-based system designed for quantitative assessment of the Autonomic Nervous System (ANS) based on Heart Rate Variability (HRV) analysis. Clusterization of the relationship between SNS and PSNS statusThis technological breakthrough is achieved by using proprietary algorithms and a new approach based on one of the leading theories of Artificial Intelligence - Marvin Minsky's Frame Theory. Nerve-Express objectively and reliably evaluates the state of ANS in "real-time" (up to 24 hours) as well as during Orthostatic test and Valsalva maneuver combined with Deep Breathing. Due to its highly sophisticated HRV analysis, Nerve-Express is the only system that enables quantification of 81 ANS states with a corresponding qualitative description for each one.
 Valsalva Maneuver combined with Deep breathing The algorithms used by Nerve-Express have been developed and tested for over twenty five years in studies involving more than twenty thousand patients . Nerve-Express implements a battery of three tests as the most comprehensive and informative combination of tests for ANS purposes: 1. Orthostatic test as the initial method for ANS provocation; 2. Valsalva maneuver combined with Deep Breathing as the optimal method for revealing the hidden abilities of the Autonomic function and distinguishing between chronic and temporary abnormalities; 3. Real-time Nerve-Monitor test as the ultimate method for ANS assessment in long-term therapy, continuous monitoring (especially, under anesthesia/intensive care), research and experimentation. Real-Time assessment may be conducted on a single patient as well as on two patients simultaneously for psychological purposes for instance: as a lay detector or psychological adaptation between crew members.
