“…The severity of a patients’ asthma can be inferred from daily variations in PEF values. This parameter is commonly used for monitoring, diagnosing and observing the evolution of asthma 4–6. Several studies have emphasized the importance of PEF measurements in hospital, outpatient and domiciliary care environments 7–9…”

OBJECTIVETo compare the measurements of spirometric peak expiratory flow (PEF) from five different PEF meters and to determine if their values are in agreement. Inaccurate equipment may result in incorrect diagnoses of asthma and inappropriate treatments.METHODSSixty-eight healthy, sedentary and insufficiently active subjects, aged from 19 to 40 years, performed PEF measurements using Air Zone®, Assess®, Galemed®, Personal Best® and Vitalograph® peak flow meters. The highest value recorded for each subject for each device was compared to the corresponding spirometric values using Friedman’s test with Dunn’s post-hoc (p<0.05), Spearman’s correlation test and Bland-Altman’s agreement test.RESULTSThe median and interquartile ranges for the spirometric values and the Air Zone®, Assess®, Galemed®, Personal Best® and Vitalograph® meters were 428 (263–688 L/min), 450 (350–800 L/min), 420 (310–720 L/min), 380 (300–735 L/min), 400 (310–685 L/min) and 415 (335–610 L/min), respectively. Significant differences were found when the spirometric values were compared to those recorded by the Air Zone® (p<0.001) and Galemed ® (p<0.01) meters. There was no agreement between the spirometric values and the five PEF meters.CONCLUSIONSThe results suggest that the values recorded from Galemed® meters may underestimate the actual value, which could lead to unnecessary interventions, and that Air Zone® meters overestimate spirometric values, which could obfuscate the need for intervention. These findings must be taken into account when interpreting both devices’ results in younger people. These differences should also be considered when directly comparing values from different types of PEF meters.

“…Além disso, o comprometimento muscular e as exacerbações infecciosas que ocorrem nesta patologia podem ocasionar variações no PFE, devendo, portanto serem avaliadas através da espirometria convencional. (11) Percebe-se a importância fundamental atribuída a este estudo, uma vez que trará informações essenciais sobre a confiabilidade dos dispositivos utilizados, podendo contribuir na construção do conhecimento e de uma política de saúde menos onerosa, por conseguinte contribuindo para o planejamento da conduta relacionada ao paciente. Logo, o mesmo visa avaliar a reprodutibilidade da medida de pico de fluxo expiratório através de um dispositivo eletrônico, em uma amostra de indivíduos jovens e sadios, e comparar os seus valores com aqueles obtidos pela prova de função pulmonar espirométrica.…”

Introdução: O estudo da função pulmonar é essencial para o diagnóstico, intervenção e acompanhamento de pacientes portadores de patologias respiratórias e é comumente medida pelo pico de fluxo expiratório (PFE). Entretanto, a variabilidade do PFE medidos por diversos aparelhos não tem sido adequadamente estudada na literatura.Objetivo: Avaliar a reprodutibilidade da medida de PFE por um dispositivo eletrônico portátil, em indivíduos jovens e sadios, comparando os seus valores com aqueles obtidos pela espirometria convencional. Metodologia: Trata-se de um estudo descritivo, comparativo, realizado na Clinica Escola de Fisioterapia de uma Universidade Comunitária em Salvador. Uma amostra de conveniência constituída por acadêmicos do curso de graduação em fisioterapia foi obtida. A avaliação funcional constou de espirometria, com manobra de CVF e mensuração do PFE pelo dispositivo eletrônico PIKO-1. Resultados: Do total de 20 universitários incluídos, 60% eram mulheres, com idade média de 24,8 ± 4 anos. A média do PFE foi de 495,2 ± 115,8 l/min. Com a espirometria de referência, os valores médios, tanto do PFE (495,2 ± 115,8 l/min) como do VEF1 (3,4 ± 0,68 l), foram maiores do que com o Piko-1 (486,7 ± 114,5 l/min e 2,85 ± 0,68 l, respectivamente; p < 0,0001), porém todas as medidas são reprodutíveis. Conclusão: O dispositivo eletrônico de medida de PFE, o Piko-1, é adequado para avaliar e acompanhar indivíduos com indicação de avaliação da função pulmonar, podendo ser um recurso alternativo para a mensuração simples do PFE.

“…When the hypoxic state is prolonged, the pulmonary circulation suffers structural alterations collectively known as remodeling, characterized by hypertrophy and hyperplasia of the arterial media, as well as by muscle fibers in the peripheral vessels. (3)(4)(5) The diagnostic procedure that is the most accurate in identifying the onset of PH is heart catheterization, and the most sensitive noninvasive technique for the early detection and monitoring of PH is Doppler echocardiography. (4,5) Echocardiography allows us to identify and quantify PH, as well as to determine its variability and the repercussions for the right heart chambers.…”

Objective: To determine the prevalence of pulmonary hypertension (PH) in patients with cystic fibrosis (CF), to compare clinical characteristics, radiographic scores, pulmonary function, and echocardiographic parameters in patients with and without PH, and to correlate echocardiographic findings with clinical characteristics, radiographic scores, and pulmonary function. Methods: This was a prospective, cross-sectional study involving clinically stable patients (aged 16 or older) enrolled in an adult CF program. The patients were submitted to clinical evaluation, Doppler echocardiography, pulmonary function tests, and chest X-rays. Results: Tricuspid regurgitant jet velocity (TRV) was obtained in 37 of the 40 patients studied. The prevalence of PH was 49% with a TRV cut-off of 2.5 m/s (18 patients) and 30% with a TRV cut-off of 2.8 m/s (11 patients). Peripheral oxygen saturation (SpO 2 ) at rest, clinical score, forced expiratory volume in one second (FEV 1 ), and forced vital capacity (FVC) were significantly lower in the group with PH. The TRV was found to correlate significantly with SpO 2 at rest (p < 0.001), clinical score (p < 0.001), radiographic score (p = 0.030), FEV 1 in liters (p < 0.001) and in % of predicted (p < 0.001), and FCV in liters (p = 0.008) and in % of predicted (p = 0.001). The single best predictor of TRV was SpO 2 at rest (p < 0.001). Conclusion: The high prevalence of PH in the CF patients studied suggests that PH should be considered in the evaluation and follow-up treatment of such patients. The best predictor of PH was SpO 2 at rest.
