Diagnose Asthma

To diagnose asthma, the doctor listens to patients from the typical noise out and performs a peak-flow measurement. The speed of the airflow in liters per minute at the beginning of exhalation is measured. If the measured value below the normal range, it runs a Bronchospasmolysetest. This measurement is 10 minutes after the person has repeated one inhaled bronchodilators. Since the restriction of lung volume in asthma is reversible, it is expected in the second measurement to improve the value of at least 15%. Confirmed the suspicion that the patient is suffering from asthma, other lung function tests can produce convincing results: Spirometry in the lung will also decide the speed of breath and body plethysmography, which describes the pulmonary function of the pressure in the lungs. In order to determine the oxygen content of blood, can be performed Blutgastest. This is the tip of the finger-rayed and a computer can calculate from the data, the oxygen concentration in the blood. To determine whether it is allergic asthma, a blood test may be helpful. In allergic asthma can be demonstrated in the blood increased immunoglobulins. The antibodies of the IgE class are typical indicators of An existing allergy. Using a skin test can be found which responds to the patient and avoid the allergen or may be sought desensitization. It can be seen with this test, the allergen is not unique, nor is the provocative inhalation test, in which the person inhales potential allergens in order to identify a possible trigger. For the diagnosis of asthma, exposure is performed before and at various times after physical exercise pulmonary function test. Should the lung heavily by training, is a strong likelihood that a disease is present in asthma burden.
