Compression-Aspiration Test

A compression-aspiration test (also known as a pneumatic test or compression test) is a method of studying the function of external respiration that allows you to evaluate the condition of the patient's lungs and bronchi.

The essence of the method is as follows: the patient is in a supine position, after which a cuff is placed on his chest, which creates air pressure. The doctor then begins to slowly *** air from the cuff, which causes the pressure in the lungs to decrease. At this point, the patient should take a deep breath, which allows the rate of air passage through the airways to be assessed.

Compression-aspiration test is carried out to diagnose various lung diseases, such as bronchial asthma, chronic bronchitis, emphysema and others. This method is also used to evaluate the effectiveness of treatment of the lungs and bronchi.

It is important to note that a compression-aspiration test can only be performed by a qualified pulmonologist or functional diagnostics specialist. Before performing the test, it is necessary to examine the patient to ensure that there are no contraindications to its implementation.

In general, the compression-aspiration test is an important method for studying the function of the lungs and bronchi, which helps the doctor make an accurate diagnosis and prescribe the correct treatment.

Compression aspiration test is one of the methods for diagnosing diseases of the bronchopulmonary system in children. It allows you to determine the degree of damage to the respiratory tract and bronchi, as well as identify the presence of complications.

The test is carried out using a special apparatus - a flatromat. It consists of a compression chamber, an aspirator and a device for controlling pressure and air flow rate. The child should be in a sitting or lying position on his back. Compression bandages are placed on the chest, which compress the airways, making it difficult to inhale and exhale. Next, the aspirator is connected to the child’s respiratory tract and the removal of mucus from the bronchi begins.

Based on the test results, the following parameters are assessed:

Expansion of the lumen of the bronchi: the absence of changes in the lumen indicates the absence of airway obstruction. Dilation of the lumen indicates the presence of obstruction. Expiratory flow: Normal expiratory flow means there is no obstruction; if obstruction is present, the expiratory flow is reduced. Bronchial reactivity to tests: assessed using a test with a change in body position, in this case there is a change in the resistance to respiratory flow. The reactivity of the bronchi may vary depending on their condition. Sputum production: When analyzing sputum, you can identify inflammatory cells, blood particles and other elements that indicate the presence of inflammatory processes in the respiratory system. The results of the compression-aspiration test are reflected in the figure. The curve on it shows the change in pressure in the respiratory tract during the test. A rise in pressure indicates dilation of the bronchi and indicates obstruction (difficulty breathing). A sharp decrease in pressure (the so-called drop) indicates the absence of obstruction and
