CAN/CSA Z23747-2018(R2023) Anaesthetic and respiratory equipment - Peak expiratory flow meters for the assessment of pulmonary function in spontaneously breathing humans
Full Description This is the second edition of CAN/CSA-Z23747, Anaesthetic and respiratory equipment - Peak expiratory flow meters for the assessment of pulmonary function in spontaneously breathing humans, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 23747 (second edition, 2015-08-01). It supersedes the previous edition published in 2008 as CAN/CSA-Z23747 (adopted ISO 23747:2007).
This International Standard specifies 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 lung 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.
