Assesment of Quality Control of Spirometric Testing in Asthmatic Patients

Spirometry is the widely used method in clinical practice in different levels of medical care. Sometimes it is use as the screening method in general practice, bus very often as the method in diagnostic procedures for asthma diagnosis, chronic obstructive pulmonary diseases, and restrictive pulmonary syndromes and so on. Very often spirometry is used as the part of diagnostic protocols for asthma treatment follow up, and many other respiratory diseases. Diagnostic procedures for asthma diagnosis sometimes include bronchoprovocation testing using methacholine or some other chemical bronchoconstrictive agents. Patients own experience for diagnostic procedures may influence to results of procedure. Experienced patients could have very well results, but they could perform very worse result so. Inexperienced patients perform worse results and that result should not be considered for diagnosis of therapeutic follow up. Medical staff, involved in spirometric procedures can influence so much, by explanation of spirometric procedures and giving support for the patients. How to assess the quality control we discuss in this paper.
