Evaluation of the transducer's flow resistance on the spirometric results
The author shows how the spirometric flow transducer resistance cooperates with the patients respiratory resistance during forced expiration. It depends on the relation existing between values of both resistances. The values of almost all expiratory lung parameters have been changed. The differences are the biggest particularly at the beginning part of the forced expiration, where airflow velocity is maximum. Then the respiratory system defect is diagnosed incorrectly and the error that appears here is classified as an error of method. Presenting a metrological analysis, the author explains theoretically in what manner the expiratory parameters can be changed by resistance of a used transducer. The measuring experiments of a group of patients confirm theoretical analysis.

More about this publication?
- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service.
