4.1.2 Test procedure for contour analysis
The test procedure consists of the following steps:
1. Measure arterial blood pressure with a certified device based on the standard oscillometric method.
2. Open the "Patient Database" tab in "AngioScan" and add a new patient by clicking on "New". Fill in
the fields: name, date of birth, gender, height and comments. Save the new patient data by clicking
"OK". This needs to be done only once for each patient. After doing so, all future test results for each
previously saved patient profile will be stored in the database.
3. Open the "Measurements" tab and select "Contour Analysis." Enter the blood pressure measured in
Step 1 in the appropriate fields.
4. Place the optical sensor on the index finger of the right hand such that the sensor cable is on the
same side of the finger as the finger nail). The sensor connected to Channel 1 (Ch1 on the device)
should be placed on the right hand.
5. If the sensor is placed correctly, the moving pulse waves will be displayed. Make sure that the "Level"
is in the range of 4 to 60, and the parameter "PI" is over 1%. Otherwise, the test results are not
reliable.
6. To start data recording, press "Record". After collecting 30 undistorted pulse waves, the test will
complete automatically. Click "Save" button to save the recorded measurements in the patient
database.
4.1.3 Contour test limitations
When conducting the contour analysis, it is important to visually monitor the pulse waves for the
presence of cardiac arrhythmias. If any significant arrhythmias are present, the heart rate variability
estimate can be unreliable.
