Fluid dynamic test

Liquorodynamic tests are one of the methods for studying cerebrospinal fluid (CSF), which allows you to evaluate its pressure, volume and speed of movement. This method is widely used in medicine to diagnose various diseases of the nervous system, such as brain tumors, hydrocephalus, meningitis and others.

To conduct a liquorodynamic test, a special syringe is used, which is inserted into the subarachnoid space of the spinal cord. The pressure of the cerebrospinal fluid and the volume it can contain are then measured. In addition, the fluid velocity is analyzed.

The results of liquorodynamic tests can help in the diagnosis of various diseases of the nervous system. For example, an increase in cerebrospinal fluid pressure may indicate the presence of brain tumors or meningitis, while a decrease in volume may indicate hydrocephalus.

However, despite its accuracy, liquorodynamic tests have their limitations. They cannot always be used to diagnose certain diseases, for example, in the presence of spinal cord injuries or in the absence of access to the subarachnoid space.

Thus, liquor-dynamic tests are an important method for studying cerebrospinal fluid and are widely used in medicine for diagnosing diseases of the nervous system. However, to obtain accurate results, it is necessary to correctly carry out the procedure and interpret the data obtained.



A liquorodynamic test is a technique for diagnosing cerebrospinal fluid - a biologically active fluid that fills the cavities of the brain, the cranial box (subarachnoid space), the ventricles of the brain, etc. The study of cerebrospinal fluid contributes to the study of metabolism between blood and brain tissue. Normally, cerebrospinal fluid is produced by the choroid plexuses of the ventricles of the brain from blood plasma. The production of cerebrospinal fluid occurs with constant low pressure, i.e. its volume is limited by the volume of brain tissue. In this regard, the study of blood circulation should be considered as a process of constantly ensuring the circulation of cerebrospinal fluid and its movement between the membranes of the brain (intracranial circulation) and the vessels of other organs and tissues. Expanding the study of cerebrospinal fluid (cerebrospinal fluid diagnostics) is possible by performing a lumbar (lumbar) puncture (puncture with a thin needle in the lumbar region). In this case, you can pump out up to 500 ml of cerebrospinal fluid. Its normal pressure is noted to be 145-180 mm of water. Art. The results of liquor diagnostics help to identify metabolic disorders between the circulatory system and the brain and the possible consequences of this, and to judge the state of the cardiovascular system of the body. Liquor plays the role of a medium for the formation of the electrical potential of the nervous system. Electrical potentials characterize the state of the membranes of brain cells. When electrical impedances increase, their function is affected. A decrease in electrical potentials is accompanied by increased excitation and inhibition, as a result of which brain performance deteriorates, memory capacity decreases, and thinking becomes difficult. They are often a consequence of various pathological conditions and affect the body’s adaptation to changing environmental conditions. Increases or decreases in brain input and output characteristics can lead to change, loss, and retention of interest and motive
