Anaesthetic and respiratory equipment. Peak expiratory flow meters for the assessment of pulmonary function in spontaneously breathing humans1 Scope 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
