Peak flow meter records peak flow or Peak Expiratory Flow Rate (PEFR), the fastest rate at which air can move through the airways during a forced expiration starting with fully inflated lungs.
Peak expiratory flow rate was measured in a standing position by using Wright's Peak Flow Meter (MicroPeak Cardinal Health UK).
CONCLUSIONS: This study demonstrated that particulate pollutants and metals such as manganese and lead in the particles are associated with a decrement of peak expiratory flow rate.
The increase in sputum clearance with the Mapleson C may be explained by previous laboratory studies which showed that the Mapleson C delivered higher peak expiratory flow rate, peak inspiratory pressure, and tidal volume (Savian et al 2005, Maxwell and Ellis 2003).
1] To measure and monitor pulmonary function, the child with asthma should be encouraged to periodically measure (one or more times daily) peak expiratory flow rates (PEFR).

All these changes the respiratory system, would improve the Forced Vital Capacity, Forced epiratory volume in 1sec, FEV1/FVC Ratio, Peak Expiratory flow rate, and respiratory rate.
The aim was to show that peak expiratory flow rate (PEFR) of a cough stimulated by the most effective US frequency and power demonstrated in the previous studies achieved an expiratory flow rate greater than the 160 to 270 L/min previously shown to be needed to clear secretions [18].
Hence, the current study was undertaken to assess the effects of meditation on heart rate (HR), systolic blood pressure (SBP) and peak expiratory flow rate (PEFR).
