The usefulness of peak respiratory flow rate (PEFR) was evaluated for investigating chronic respiratory diseases in children. The investigations were carried out in 1088 children aged 8-10 years. The reproducibility of the test, the accuracy confirmed by the results of medical, laryngological, radiological, biochemical investigations and respiratory function tests, as well as the cost of testing, easiness of test application in mass examinations and acceptance by the children were analysed. In the light of these investigations PEFR is regarded to be a very useful simple test which should be widely introduced. It was found also that it is one of the simplest function tests permitting quantitative evaluation of the degree of reduction of ventilation ability of the lungs in children. |
