Handling and measurement procedure

Simple handling for routine use, also by support personnel.

The great advantage of VascAssist is that it is very simple to handle. This makes it ideal in routine use for the early diagnosis of PAOD.

Anwendung

Preparations

After getting the proband to lie down flat VascAssist’s four blood pressure cuffs are applied to the upper arms and ankles. The Patient ID and the patient’s weight are entered into VascAssist.

Rest period

A rest period of at least 10 minutes prior to starting to measure makes the measurements more reliable and reproducible and is therefore indispensable.

Measurement

Select first the measurement mode ABI measurement and start the measurement cycle with "Ok".

First the blood pressures of upper arm and ankle of the right side of the body are measured automatically, and then those of the left side. All blood pressure values, pulse rates and the calculated ABI values for the right and left sides of the body are immediately available to you shown on the display of the equipment.

Display

After this, with the blood pressure cuffs still on the patient, you can determine the pulse wave velocities of the left and right sides of the body by simply pressing a button. This measurement also only takes a few minutes and ends with the display of the results.

Analysis

As the readings for ABI and PWV are directly shown on the display of VascAssist no further analysis is necessary. Optionally the results can be printed out using an attached printer.
If you are interested in a more extensive analysis in which you can also see the measurement results shown graphically in the context of normal values, then you can use the optional analysis software VascViewer. Measurement results from VascAssist can be input and processed online in the software package.

Instructions for using VascAssist

  • Illustrations, labels and color codes on the blood pressure cuffs show you the correct place to attach the cuff so that a swap can be practically ruled out.
  • As for a normal blood pressure measurement the cuffs should be attached tautly but not too tight. Exact orientation on the arteries is not imperative as the measurement process is oscillometric and the pulse pressures are picked up over the whole blood pressure cuff. You should nevertheless try to place the marker labeled “Artery” as near as possible to the corresponding artery, so that the measurements are performed under standardized conditions.
  • Take care that items of clothing that are pushed aside do not cause blood congestion in the limbs.
  • Do not apply the blood pressure cuffs over clothing but always directly on the skin. Clothing distorts the pulse pressure curves recorded and results in incorrect measurements.
  • The patient or proband must lie down flat. A slope of a maximum of 10% for the head end of the couch is possible.
  • Repeat the measurements for ABI and PWV several times with a few minutes in between and compare the results. The closer the results are to each other the more reliable they are.
