Dobrovolskoy Symptom

The Dobrovolskaya symptom is a diagnostic method developed by the Soviet surgeon Natalya Aleksandrovna Dobrovolskaya (born in 1878). This method is used to determine the presence of fluid in the pleural cavity.

The volunteer symptom is that the patient lies on his back with his knees bent and his hands placed on his stomach. The doctor then applies gentle pressure on the patient's abdomen to create negative pressure in the pleural cavity. If the patient experiences pain or discomfort when pressing, this indicates the presence of fluid in the pleura.

This method has high sensitivity and specificity, making it a useful tool for diagnosing diseases of the lungs and pleura. However, like any other diagnostic method, the Dobrovolskaya symptom cannot be the only criterion for making a diagnosis. It must be supplemented by other examination methods, such as x-rays, computed tomography or ultrasound.

Volunteer symptom is a rare and not fully understood pathological condition in which pressure is felt in the chest, accompanied by pain under the sternum. This condition occurs due to problems with the heart muscle, blood vessels, or nervous system. Dobrovsky's symptom is usually accompanied by tachycardia, arrhythmia, symptoms of cardiopathy and other abnormal conditions that can lead to serious consequences for human health and life.

Description and pathophysiology of Dobrovsky's symptom. Dobrovsky's symptom consists of two physiological signs: cardiac and pulmonary respiration. Cardiac breathing begins with a deep breath, followed by holding the breath for a few seconds to eliminate respiratory dysfunction. The hold is followed by a noisy exhalation and repeated breathing.

In pulmonary breathing, inhalation is slow and the air passes through the upper respiratory tract.
