EN ISO 23747:2015 (E) DIN EN ISO 23747:2015-12 3 IntroductionThe development of a standard for peak expiratory flowrate (pef) measurement is considered important for clinicians
34、to use in diagnosing and monitoring lung and airway conditions by ensuring that all medical devices for such purposes meet minimum levels for safety and performance. An agreed standard means that a peak expiratory flow meter (pefm) can be tested to meet the same requirements with the latest accepted
35、 methods. Clinicians and patients can then be confident that a pefm is fit for the purposes for which it is intended.The American Thoracic Society has been foremost in proposing initial standards for testing a pefm (see Reference 15). They have proposed 26 waveforms suitable for testing pef, which a
36、re deemed suitable for checking that a pefm can correctly measure pef.The work of Miller et al. (see Reference 18) first showed the problem of pefm inaccuracy and they have subsequently defined the population characteristics of the pef profile (see Reference 21) and demonstrated limitations of pump
37、systems for testing a pefm (see Reference 20). The European Respiratory Society has published a comprehensive statement on pef (see Reference 21).This International Standard is based on the best currently available evidence concerning the methods and waveforms suited for testing a pefm (see Referenc
38、e 17).Throughout this International Standard, text for which a rationale is provided in Annex A, is indicated by an asterisk (*).In this International Standard, the following print types are used: Requirements and definitions: roman type. Test specifications: italic type. Informative material appear
39、ing outside of tables, such as notes, examples and references: in smaller type. Normative text of tables is also in a smaller type. Terms defined in this particular standard or as noted: small capitals type.EN ISO 23747:2015 (E) DIN EN ISO 23747:2015-12 4 1 ScopeThis International Standard specifies
40、 requirements for a peak expiratory flow meter (pefm) intended for the assessment of pulmonary function in spontaneously breathing humans.This International Standard covers all medical devices that measure peak expiratory flowrate in spontaneously breathing humans either as part of an integrated lun
41、g function medical device or as a stand-alone medical device.Planning and design of products applying to this International Standard are to consider the environmental impact from the product during its life cycle. Environmental aspects are addressed in Annex E.NOTE Additional aspects of environmenta
42、l impact are addressed in ISO 14971.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
