EXPIRATORY FLOW RATE CALCULATOR

摘要

The present invention is a method for determining human expiratory flow rate, comprising a peak flow meter and a zone calculator. The peak flow meter is used to determine what the user's peak expiratory flow rate is in conjunction with medical data compiled on the zone calculator. The individual's peak expiratory flow rate and predetermined sub-optimal values are applied to the peak flow meter as color zone settings. The peak flow meter thus set is ready for the individual to use to determine whether he is functioning in the peak expiratory flow rate color zone, or one of the sub-optimal expiratory flow rate color zones. The color zones correspond to specific remedial measures to be followed by the individual in case of sub-optimal expiratory flow rate.
