Votchala-Tiffno Proba

Votchala-Tiffno Sample: history, operating principle and application

The Votchala-Tiffenau test, also known as the V/T test, was developed in 1947 by Soviet physician Boris Votchal and French scientist Roger Tiffenot. This test is used to determine the volume of exhaled air and the speed of air flow during exhalation.

The principle of operation of the V/T test is based on measuring the volume of exhaled air during the first second after the start of exhalation. The patient is asked to inhale deeply and then exhale into a special device that measures the volume of air and the speed of air flow during exhalation. The measurement results are then used to determine important parameters such as the volume of air exhaled in the first second (FEV1) and FEV1/FVC (the ratio of FEV1 to the total volume of air exhaled).

FEV1 and FEV1/FVC are important indicators of lung function. Their use allows doctors to determine the presence and extent of obstructive pulmonary disease, such as asthma and chronic obstructive pulmonary disease (COPD).

The use of the V/T test is not limited to the detection of obstructive pulmonary disease. It can also be used to evaluate the effectiveness of treatment, monitor disease progression, and determine the physical fitness of athletes.

Although the V/T test was developed more than 70 years ago, it remains a reliable and widely used method for assessing pulmonary function. Its use in clinical practice helps doctors diagnose and treat obstructive pulmonary diseases, as well as evaluate the effectiveness of treatment.



The Votchal-Tiffenau test is a method for assessing the function of external respiration, which was developed by the Soviet therapist Vladimir Vasilyevich Votchal and the French scientist Rene Tiffenault. This method is used to diagnose lung diseases such as bronchitis, asthma, pneumonia, etc.

The essence of the method is to measure the volume of air that passes through the lungs over a certain time. To do this, the patient needs to take a deep breath and exhale, after which the doctor measures the volume of air that remains in the lungs. The patient then takes a few more breaths and the doctor re-measures the volume of air.

The difference between the first and second air volume measurements is an indicator of respiratory function. If the function of external respiration is impaired, this may indicate the presence of lung disease.

The Votchala-Tiffno test is one of the most accurate methods for diagnosing lung diseases. However, to obtain correct results, it is necessary to correctly carry out the air volume measurement procedure and interpret the results.

Thus, the Votchala-Tiffno test remains an important method for diagnosing lung diseases and allows for timely identification of diseases and initiation of treatment.
