This peak flow calculator allows you to calculate your normal peak expiratory flow (PEF), as well as your peak expiratory flow ratio (PEFR). The ratio is a relation between your measured PEF and the normal value, or, if you know it — your personal best. PEFR is a valuable, useful, ...
A peak flow calculator used in cooperation with zone indicators ON the peak flow meter permits a user to customize the peak flow meter for that user's predicted personal best exhalation range.ナトール,マイケル
