What is the AngE?

The AngE Angio Experience is a simultaneous 4-channel pulse oscillography device with additional ECG-trigger. This means, the patient's pulse wave is measured with 4 cuffs simultaneously, which provides a much better comparison of the extremities pulse waves and an improved Dopplerindex calculation.
The pulse waves are recorded at different cuff pressures. The mean arterial pressure is determined by the maximum amplitude. The comparison of the mean arterial pressure leads to a result similar to the ABI.
Additionally, the AngE has a built-in ECG-Trigger which works simultaneous to the cuff-measurements, allowing the measurement and calculation of the pulse wave runtime and pulse wave velocity.

The alternative solution to ABI

These days, even in our health care system, cost effective operation is a necessity. AngioExperience (AngE) has been developed to obtain the diagnosis of a peripheral arterial occlusive disease quickly, reliably and with cost effectiveness, without stress for the patient.
Therefore, the classic, more time consuming and hard to document ABI measurement is a relic from the past.
Using the oscillometric principle developed by Gesenius and Keller, the pulse waves are recorded at different cuff pressures. The mean arterial pressure is determined by maximum amplitude. The comparison of the mean arterial pressure leads to a result similar to the ABI.

The system is able to record the pulse waves at fingers and toes as well as ankle and wrist at 4 channels. Due to the simultaneous measurement, there is no time difference between the measurements on the single extremities as with the ABI measurement. This delay between the individual determinations of blood pressure values leads to an inaccuracy which is avoided by the AngE. In addition the simultaneous recording allows the comparison of time values between the limbs.


Patients suffering from diabetes often have very calcified vessels (mediasclerosis) which can not be compressed. Therefore, the ABI results are unusable.

Using the finger and toe measurement of AngE, reliable results can be obtained, because the mediasclerosis affects the toes only in less than 1% of such patients.
Measuring this way, even with patients suffering from mediasclerosis, a fast and consistent diagnosis is possible. This early detection of pAOD avoids lots of complications for the patient.

Pulse Quality

AngE provides a multitude of additional parameters compared to the ABI measurement. Where the ABI only provides pressure values of the limbs, AngE records the pulse wave which allows obtaining a detailed pulse wave analysis. Parameters such as rise time, amplitude and the optical appearance of the puls wave can be evaluated.

The calculation of RI(reflection index) and SI(stiffness index) allow the identification of patients with a high vascular risk by the inclusion of the dicrotic wave into the measurement. With medicamentous provocation, the endothelial function can be examined.

ECG Trigger

With the recording of the ECG signal it's possible to use the R-wave to obtain a trigger point, thus allowing the measurement and calculation of pulse wave runtime and pulse wave velocity. This parameters increase in their importance according to the evaluation of the state of the vessels e.g. in clinical monitoring of patients suffering from hypertension.

The AngE is shipped with two electrode clamps in order to minimize the effort involved in the measurement. The electrodes just need to be placed onto the patients wrists.
