What is the test of Genci? Stange's test and technique

The functional test of Gencha is made witha delay in breathing. This test helps to understand how well the body is supplied with oxygen. This test determines the degree of training of the patient's body.

If breathing lingers on exhalation, then the study calls the breakdown of Genci. But there is another similar procedure. A study with a breath-holding breath on inspiration is called Stange's test.

genci test

Carrying out breathing tests by Stange and Genci, doctorsestimate the duration of the respiration delay and the change in heart rate. How is the last indicator calculated? By the ratio of the frequency of contractions during the delay of breathing to the heart rate at rest. We understood what the test of Stange and Genci is. Now it is worth considering the technique of procedures.

What do you need to sample?

How is the Stange test performed? In order to make a test, the following tools are needed:

breathing tests of rod and genci

  1. Stopwatch.
  2. Clamp for the nose.

Step-by-step procedure for conducting a test of Stange

Before the procedure begins, the physician fixes the pulsepatient. As a rule, the number of heart beats is counted for half a minute, after which the obtained score is multiplied by two. Calculation of the pulse is carried out in a standing position. The results are recorded.

Next, a person needs to do three normal inhalations and exhalations (not at full depth). After this, the patient should take the deepest breath and hold his breath.

The test rod test and Genci are determined

A special clip is put on the nose, although it can bejust pinch your fingers. The doctor detects the time delay of breathing with the help of a stopwatch. After exhalation, when the patient's breathing is restored, the specialist again measures the pulse. If necessary, then repeat the test can be done in five minutes.

Evaluation of the results of the Stange

If the breath hold was less than 39 seconds, this result is considered unsatisfactory and may indicate a problem with the respiratory system.

The time from 40 to 49 seconds issatisfactory. If a person can hold his breath for more than fifty seconds, then this result is considered good and indicates physical fitness.

How is the Genci test done?

In this case, the retention of breath occurs on exhalation. Genci's test also helps determine the degree of fitness and body oxygen supply.

What equipment is needed for the study?

genti functional test

  1. Stopwatch.
  2. Clamp for the nose. The test of Genci can be carried out without him, since the nose can be clamped with fingers.

The procedure for carrying out such a procedure

As with the previous study, first you need to calculate the patient's pulse. To obtain accurate results, the frequency of heart beats is sometimes measured twice.

The patient does three breaths and exhalations, but notmaximum full (approximately 3/4 of the total volume of the lungs). Then you need to do a full exhalation and pinch your nose with your fingers or a special clamp. Time is recorded using a stopwatch. After restoring normal breathing, you need to count the pulse again.

Genci's test. Indicators of the study

If a person managed to delay breathing for less than 34 seconds on expiration, then such a result is considered unsatisfactory.

The indicator from 35 to 39 seconds indicates normal operation of the respiratory system. If the delay time exceeds forty seconds, the result is considered good.

It is also necessary to evaluate the heart rate indicators.The PR value (heart rate response rate) is calculated according to a certain formula. It is necessary to divide the heart rate after the delay of breathing into heart rate indicators obtained before the study. Normally, this indicator should not exceed 1.2. If it is higher, this may indicate the presence of problems in the work of the cardiovascular system and its adverse reaction to oxygen deficiency.

Respiratory process and its components

The respiratory process in the human body consists of three stages. They include:

  1. External respiration (a gas exchange between the lungs and the environment).
  2. Delivery of oxygen by blood to other organs of the human body.
  3. Internally breathing (gas exchange cells).

The state of the human body directly depends on how much oxygen has flowed to the inner cells and tissues. These processes are provided by the work of respiratory organs and the cardiovascular system.

Hypoxia of tissues, therefore, can be caused not only by oxygen deficiency in the environment or disruption of the respiratory system, but also by cardiovascular diseases.

When examining the patient's respiratory system, doctors determine the volume of the lungs, the rhythm of breathing, and its depth. Sometimes the degree of endurance of organs is additionally measured.

A small conclusion

One of the methods of studying lung function is the test of Stange and Genci. With their help, you can identify abnormalities in the body, which can not always be determined by conventional methods.

rod and genci test

If there are anydiseases, for example anemia, then the delay in breathing is reduced. The test test of Stange and Genci is defined as a study that helps assess the body's ability, its sensitivity to oxygen and training.

You can make such samples yourself, becausethe technique of execution is very simple. Therefore, any person can test himself and understand if he has any problems with the work of the respiratory and heart. For sampling, you only need a stopwatch and a nose clip (you can do without it).
