VasoScreen 2000 - System for the evaluation of the Ankle-Brachial Index (ABI)

VasoScreen 2000
This device is for arterial vascular diagnosis based on simultaneous measurement of 4-channel blood pressure on the upper arms and ankles (oscillometric method) for the estimation of ankle-brachial index (ABI). This new approach is a great alternative to the often-used Doppler method.

The unit can only be used in conjunction with an external computer on which the Windows Cardio-Vascular-Lab software is installed. The choice of computer depends on the given application and the environment in which the measurement system will be used.

APPLICATIONS
Allows for ABI estimation, a lateral comparison of pulse peripheral wave velocities, and an evaluation of pulse curve parameters

Arterial screening for the early detection of arteriosclerotic vascular changes
diagnosis of peripheral arterial occlusive diseases (PAOD)
Recognition of subclavian artery stenosis
Control of therapy after dilation, vascular training or drug therapy

Compared to Doppler-assisted ABI measurement, the advantages are:

simultaneous measurement on arms and ankles (4 cuffs) to exclude the influence of blood pressure changes during the examination process
Operator-independent procedure that can be easily delegated
The exam lasts less than 3 minutes
computer-controlled automated measurement procedure
Computer-aided evaluation and classification of measurement results, including lateral comparison
Patient database and off-line data analysis capabilities
Data export capability (GDT, PDF)
Additional options: Peripheral pulse wave velocity and pulse wave analysis
Combination with other VasoScreen and CardioScreen devices is possible
 

Doppler-assisted ABI measurement is time-consuming and only provides reliable results if the examination is carried out by an experienced operator. In addition, blood pressure values cannot be detected on the arms and ankles at the same time, so that any changes in blood pressure during the examination process are not taken into account, which could lead to measurement errors. Comparative studies have shown an excellent correlation between oscillometric and Doppler methods.

A lateral comparison between peripheral pulse wave velocity and pulse wave analysis provides additional information on ABI parameters for a more in-depth diagnosis.
