Objective:
To explore a method for early detection of diabetic autonomic neuropathy (DAN) on the basis of analysis of galvanic skin response (GSR).
Methods:
In 25 randomly selected diabetic inpatients (14 with clinical DAN symptoms), GSR signals were collected from the fingers of both hands based on Virtual Instrumental WorkBench-LabVIEW and compared with those acquired from normal subjects.
Results:
The GSR indices of patients either with or without DAN were different from those of normal subjects, and even in the same patients, the changes of these indices after clinical treatment were also obvious.
Conclusion:
GSR detection and analysis can help understand the impairment of the autonomic system and facilitate DAN assessment.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
