详细说明
Diabetes mellitus related vascular alterations are associated with an increased risk of hypertonia, atherosclerosis, neuropathy, diabetic retinopathy, and further more.
Increased vascular rigidity, which is based on the increased stiffness of vessels caused by vascular damage leads to an increase of pulse wave velocity. This assumption is based on the Moens-Korteweg-equation which is calculated using the modus of arterial vessel elasticity, arterial vessel wall thickness, the arterial radius and blood viscosity.

Pulse wave arrival time difference between finger and toe, duration of diabetes
大体时间：1 Minute data recording of the pulse waves at four sites.

The pulse wave is recorded by plethysmography using a pulse-oximeter and a continuous noninvasive arterial blood pressure measurement (CNAP-500) device, both on the finger and toe.
The time between these 4 recorded waves is then calculated.
The influence of age, duration of known arterial hypertension, cigarette smoking (pack-years) and diabetes mellitus.
