[Evaluation of the PEFR (peak expiratory flow rate) measurement error in using Wright's apparatus]
Insights
Peak respiratory flow rate (PEFR) is a valuable, simple test for diagnosing chronic respiratory diseases in children. This cost-effective method is easy to administer during mass screenings and accurately assesses lung ventilation ability.
Area of Science:
- Pediatric Pulmonology
- Respiratory Physiology
Context:
- Chronic respiratory diseases pose a significant health burden in children.
- Accurate and accessible diagnostic tools are crucial for early intervention.
- Mass screenings are essential for identifying respiratory issues in school-aged populations.
Purpose:
- To evaluate the utility of peak respiratory flow rate (PEFR) in assessing chronic respiratory diseases in children.
- To determine the reproducibility, accuracy, cost-effectiveness, and ease of use of PEFR testing.
- To assess children's acceptance of PEFR testing during mass examinations.
Summary:
- Peak respiratory flow rate (PEFR) testing was conducted on 1088 children aged 8-10 years.
- The study analyzed PEFR's reproducibility, accuracy (validated against medical, radiological, and functional tests), cost, ease of application, and acceptance.
- Results indicate PEFR is a highly useful, simple, and quantitative test for evaluating reduced lung ventilation in children.
Impact:
- PEFR is recommended for widespread introduction in pediatric respiratory health assessments.
- The test provides a simple, quantitative measure of lung ventilation impairment.
- Facilitates early detection and management of pediatric respiratory conditions through accessible mass screenings.
Abstract:
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.
