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).
The result of the test is called peak expiratory flow rate (PEFR).
