| Background: One of the measures of the pulmonary function is the peak expiratory flow (PEF) that can be defined as the major flow obtained in an expiratory pressure after a complete inspiration to the level of the total lung capacity. This measure depends on the effort and strength of expiratory muscles, the airway diameter and the lung volume. Objective: To compare the results of the peak expiratory flow in healthy male and female obtained in a seated position and dorsal decubitus (DD), right lateral decubitus (RLD) and left lateral decubitus (LLD). Method: Thirty young subjects with mean age 22.7 years, healthy and non-smokers were included at the study, 15 of male sex. They did spirometry and IPAQ questionnaire to check the normal pulmonary function and physical activity level. The measures of PEF were performed in four positions, being performed 3 measures in which position, in a random order. Statistical analysis was performed according to Student's t test, with significance level set at 5%. Results: There was a difference between the values obtained in sitting position(481±117.1 L/min) with DD(453.2±116.3 L/min) and RLD (454±112.9 L/min) (p<0.05), however, did not find a significant difference between the sitting position and LLD (469±83 L/min). Conclusions: Body position affects the values of PEF, with decreasing values in DD and RLD. The LLD can be an alternative to optimize the expiratory flow in situations of constraint to the sitting position.Keywords: peak expiratory flow rate; meter; physical therapy.

“…According to the guidelines for pulmonary function tests (18), the various brands of PEF generally differ in the results observed for the same individual, and often exhibit non-linearity on the meters (21). In this study we compared the values obtained from three different devices of PEF and significant difference was observed between the Mini-Wright ® and Assess ® meters in both genders, between the AirZone ® and Assess ® only in men, and between the Mini-Wright ® and AirZone ® only in women.…”

Introduction:The peak expiratory flow (PEF) is a practical method that evaluates the caliber of the proximal airways. The ease in handling and the low cost of portable PEF meters made their use frequent. However, few studies have examined the correlation between the different equipment and compared their reference values. Objective: Analyze the correlation of three portable meters of PEF and check if the reference values are applicable in the studied population. Methods: 168 healthy individuals, of both genders, ranging in age from 20 to 80 years, had their PEF measured in Mini-Wright®, Assess® and AirZone® and the values obtained were compared to those predicted by Leiner et al. (1963) and Nunn and Gregg (1989). Statistical analysis was performed by the Kolmogorov-Smirnov tests, ANOVA, Wilcoxon test, Spearman correlation and analysis of agreement of Bland-Altman (p< 0.05). Results: There was significant difference in the values of PEF obtained between the Mini-Wright® and Assess® meters in both genders, between the AirZone® and
