Cardiac Autonomic Neuropathy Analysis System model CANS 504 is a PC based system to analyses Sympathetic and Parasympathetic autonomic nervous system response of the patient. 
The system uses ECG Cardio-Tachogram (R-R interval) and advanced automatic NIBP (Non-Invasive Blood Pressure) module to conduct a battery of six tests. Being fully automatic, it eliminates the need of manual recordings, readings and calculations. These tests are done with patients co-operation and the PC onscreen panel helps the to complete the tests successfully.
