Execution and respiratory performance tests: all that should be known

How to perform the exam excludes the type and we call the most prominent performance and respiratory performance tests: 1. The test testing This test is very old, which is selective of asthma, but the result of its result is 65% – 70% of the medical conditions. 2. Histamine or metacholin challenge testing or metolin is inhaled for two minutes with a gradual double concentrations, until it causes a 20% blockage according to the evaluation of the lung performance. This test is very sensitive to asthma, but its choice is 50%less; Because other patients with multiple lung diseases will respond to this test in the same way. 3.. The challenge test by adenosin This test is also made by inhalation, which is a high -rate sensor of up to 95%, and its selection is more high and up to 80% in asthma diagnosis. These tests are performed for children who can generally work together at the age of more than 6-7 years. 4. Test of the bronchial challenge using breathing sounds. Air Bronchial Challenge test is performed using breathing sounds with the undergraduate children who cannot do regular tests to evaluate the performance of the lung, it is possible to do the same challenge tests by inhaling a clinical reaction. That is, inhalation of the materials that kumulate to the appearance of the pathological symptoms of the bronchial blockage, that is, the whistle, which in the case of listening to the patient can be heard, this pathological response is called the concentration that causes the scale, ie the yellowness (provocation concentration). 5. Nitric oxide exhale This test is widely used as a general scale of non -bacterial infection in the airways. It has been found that the percentage of nitric oxide exhalation is large in adults with asthma and low among people with cystic fibrosis or patients with chronic bronchial infections. Measuring the amount of nitrogen breathing requires cooperation from the patient so that he is asked to do a specific exhalation pressure.
