AngioScan Medical Tests
4.3.1 Patient preparation requirements
1. The test can be conducted at different times of day. However, when the purpose of the study is to
evaluate the effectiveness of a therapy (eg, hypertension, heart disease, diabetes), then the tests
should be performed in the morning to eliminate the influence of the circadian rhythms.
2. Smoking, vasoactive drugs, caffeine, alcohol, and other stimulants, moderate and intense physical
activity should be stopped one day prior to the test.
3. Immediately before the test, the subject must be at rest fpr at least 10 minutes in a warm, dark, quiet
room.
4. The test should be done either in the supine or seated position. The test hand should be placed at the
heart level. The test results recorded while sitting and in supine positions have marked differences.
This is due to the changes in transmural pressure in the aorta and the arteries of the arm. If the
contour analysis of pulse waves collected during pharmacological tests is needed, the tests should be
always performed on the same arm (the right hand is preferred due to the anatomic differences in the
brachiocephalic area).
5. The test should be conducted in a warm, darkened and quiet room.
4.3.2 Pharmacological test procedure
Pharmacological test procedure consists of the following steps:
1. Measure arterial blood pressure with a certified device based on the standard oscillometric method.
2. If necessary, create a new patient profile in the "Patient Database" window. To add a new patient,
click "New" and fill out the form: name, date of birth, gender, height and comments. Then click "OK"
to save the patient data. 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. After adding the patient to the database, open the "Measurements" window and select the
"Pharmacological Test" tab. Enter the measured blood pressure in the appropriate fields.
4. Place the optical sensor on the patient's index finger ensuring that the connecting the sensor cable is
on the same side as the finger nail. The sensor channel 1 (Ch1 on the device) should be placed on the
right index finger.
5. Once the sensor is placed on a finger, the moving pulse waves are seen on the screen. 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.
