Examination of the body

Whole body plethysmography

To implement the method of plethysmography, special devices are used - plethysmographs, of various modifications - electrical, water, photographic, mechanical.

Testicular biopsy: puncture, open

Diagnostic procedure - testicular biopsy - is relatively rare, but it is considered very informative to determine the causes of impaired fertility in men, as well as other diseases associated with the male reproductive system.

Blood pressure measurement: algorithm, norm

Arterial pressure is the pressure that blood exerts on the walls of the vessels. This pressure is somewhat less in peripheral, smaller vessels. It fluctuates due to the contractile function of the heart.

Study of arteries

Peripheral arterial circulation disorders are usually more severe in the elderly due to the deterioration of collateral blood flow.

Study of veins

. Evaluation of the veins is important for examination and palpation. When blood flow is disturbed in a large vein, collateral circulation rapidly develops.

Percussion and palpation of the spleen

There are many methods of percussion of the spleen, which is explained by the difficulties in choosing the optimal anatomical-topographical landmarks.

Duodenal sounding of the gallbladder

Until recently, it was very common to study the biliary tract with duodenal probing, which is the introduction of a probe into the duodenum to obtain its contents.

Quantitative electroencephalography

Quantitative (digital, computer, paperless) electroencephalography arose in connection with the rapid development of electronic computing as a further development of the EEG method.

Registration of evoked potentials of the brain

Registration of evoked potentials is one of the areas of quantitative electroencephalography.

Constant potentials of the brain

Registration of the level of the permanent potential of the brain is a special section of brain electrophysiology.
