30、thout to EN ISO 26782:2009/AC:2009 Introduction A spirometer is a medical device that records physiological lung ventilation volumes within the range of the vital capacity. The timed volumes that a PATIENT is able to expel after a maximal inspiration give a reliable method of assessing lung function
31、. These spirometric assessments are used, for example, to screen individuals at risk of lung disease, to give objective measures in the presence of lung disease, to evaluate symptoms and pre-operative risk and to record the effect of therapeutic intervention. A SPIROMETER can also be used in evaluat
32、ing pulmonary disability, public health and clinical trials. The American Thoracic Society (ATS) and the European Respiratory Society (ERS) have been instrumental in developing recommendations for the standardization of lung function testing, including guidelines for spirometry 6, 7. There is howeve
33、r no recognised international or national standard for SPIROMETERS with reliance for accuracy, repeatability, etc. based on objective test methodology and on meeting defined tolerances when tested with a carefully selected set of defined test profiles such as those published by the ATS. This Interna
34、tional Standard addresses this problem by developing a standard for a SPIROMETER to give the clinician the confidence that any SPIROMETER used meets agreed standards of accuracy, repeatability, electrical safety, etc. The minimum safety requirements specified in this particular International Standar
35、d are considered to provide a practical degree of safety in the operation of SPIROMETERS. The requirements are followed by specifications for the relevant tests. A “rationale and guidance” section giving some explanatory notes, where appropriate, about the more important requirements is included in
36、Annex A. It is considered that knowledge of the reasons for these requirements will not only facilitate the proper application of this International Standard but will, in due course, expedite any revision necessitated by changes in clinical practice or as a result of developments in technology. Howe
37、ver, this annex does not form part of the requirements of this International Standard. In this document, the following print types are used: requirements, compliance with which can be verified, and definitions: roman type; notes and examples: smaller roman type; description of type of document chang

39、uirements for SPIROMETERS intended for the assessment of pulmonary function in humans weighing more than 10 kg. This International Standard applies to a SPIROMETER that measure timed forced expired volumes, either as part of an integrated lung function device or as a stand-alone device, irrespective
40、 of the measuring method employed. Devices intended for continuously monitoring PATIENTS are outside the scope of this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
