[Evaluation of weather-dependent dyspnea by means of body plethysmographic study of bronchial reactivity].

By body plethysmographic investigations including the test of the bronchial reactivity (ultrasound aerosol of a 0.01% acetylcholine solution) was demonstrated that in dependence on the degree of the manifest disturbance of ventilation the frequency of the bronchial hyperreactivity (increase of the total resistance by at least 3.0 cm H2O/l/s compared with the initial position) increases. The constellation of findings mentioned leads to a large increase of dyspnoea depending on weather.
