“…Most of the reference equations for PEFm are based on European and Asian populations living at sea level, and although some studies reported a good correlation between PEFm and those obtained by spirometry (PEFs), some authors have reported that PEFm may underestimate the value of expiratory flow when obtained in cities that are at elevations above sea level, probably due to air density [ 14 , 15 ]. On the other hand, very few studies have reported normal PIF values [ 10 , 11 ].…”

Background Peak inspiratory and expiratory flows (PIF, PEF) are parameters used to evaluate the mechanics of the respiratory system. These parameters can vary based on whether they are measured using mechanical devices vs. spirometry and based on the barometric pressure at which the measurements are obtained. Our objectives were (1) to report the normal values and variability of PEF and PIF of a Latin American population living at a moderate altitude (2240 m above sea level), (2) to analyze the adjustment of reference values obtained at sea level with those obtained in healthy subjects living at a moderate altitude, and (3) to assess the correlation between PEF obtained by spirometry (PEFs) and PEF obtained by mechanical devices (PEFm). Methods In this prospective and transversal study, men and women with good respiratory health aged between 2.8 and 68 years old were invited to participate. Randomly, they underwent spirometry (to measure PEFs and PIFs) and mechanical flowmetry (to measure PEFm). Results A total of 314 subjects participated, with an average age of 24.3 ± 16.4 years; 59% were Women. The main determinants for the reference equations were age, weight, height and sex at birth. The agreement of the PEFm, PEFs and PIFs values was inconsistent with that reported by other authors, even at the same barometric pressure. The association between PEFm and PEFs was r = 0.91 (p < 0.001), and the correlation coefficient of concordance was 0.84. Conclusions The PEFm, PEFs, and PIFs measurements in individuals living at moderate altitudes are different from those found by other authors in cities with different barometric pressures and ethnicities.

The diagnosis, treatment, and follow-up of chronic obstructive pulmonary disease (COPD) and asthma are crucial in family practice. However, the utilization of pulmonary function tests in Turkey has been not sufficient and also the interpretation of spirometric test results is not adequate due to lack of knowledge. This study was aimed to provide a course on using office spirometry and peak flowmetry for family physicians and to help them become competent in approaching the respiratory system. Methods: A course with an original and unique content was developed and administered to family physicians. A 20-item test covering the educational content was applied to the participants before and after each course. Oral and written feedback was taken from the participants to evaluate the course program. Results: 115 family physicians joined the study. Pre-test and post-test scores were 40.39±12.8% and 75.22±11.12%, respectively. Primary outcome of the study was the difference in the mean test scores before and after the trainings, which revealed significant (p<0.001). Conclusions: Extending this kind of courses to all family physicians might be useful in facilitating the diagnosis of respiratory diseases, enabling more conscious diagnoses, and possibly more efficient utilization of the health resources, leading to better health outcomes.
