Compression Test

Compression test (lat. comprimo, compressum squeeze, compress; synonyms: compression-tonometric test, expression test) is a method of studying blood vessels, which consists of short-term clamping of the artery and subsequent assessment of the restoration of blood flow after the compression is removed.

The test is carried out to identify violations of arterial patency and assess the state of collateral circulation. Normally, after compression is removed, pulsation distal to the compression site is restored quickly and completely. Slow restoration of blood flow or its absence indicates obliterating diseases of the arteries.

The compression test is easy to perform and informative for the screening diagnosis of peripheral arterial diseases. It allows you to determine the level of damage and assess the severity of circulatory disorders in the extremities.

Introduction. A compression test is a method for studying blood pressure and heart rate, which is used to diagnose arterial hypertension (high blood pressure) and other cardiovascular diseases. This method is based on measuring the blood pressure in the artery after the pressure in the arm has risen below atmospheric pressure.

Description. Currently, there are 2 ways to perform a compression test. In the first option, pressure is applied to the arm using a cuff. It is placed on the shoulder and inflated until the movement of the pulse wave at the wrist stops, which indicates the cessation of the systolic rise in blood pressure. After this, the measuring device is removed. In persons who have suffered thrombosis of large arteries, the state of pulsation subsides faster than in healthy people. Stabilization of the sphygmotonometer in this case is due to a decrease in blood pressure during arterial stenosis below the cavity of the pulmonary circulation. This leads to insufficient filling of the upper half of the body with blood, and therefore the atria. The amount of blood in the heart itself no longer increases, since the current through the floor
