[Spirographic studies and measurement of airflow resistance in evaluation of bronchial hyperreactivity in children with asthma].
An analysis of spirographic studies and measurement of airflow resistance in diagnosing bronchial hyperreactivity in 27 children with bronchial asthma was made. Histamine was used for provocation tests. Bronchial hyperreactivity was found in 85.2% of the studied children. The most useful for predicting existence of bronchial hyperreactivity proved to be FEV1, FEV, and PEF measurements. After histamine provocation airflow resistance rose from 0.42 kPa/l/s to 0.63 kpa/l/s. that is by 50%. Both tests spirometric and airflow resistance proved to be comparable in 70.4%. Usage of both methods allows a better chance of diagnosing bronchial hyperreactivity.
