| The objective was to evaluate the effect of continuous positive airway pressure (CPAP) in the respiratory rate (RR), tidal volume (TV) and minute volume (MV) in patients after bariatric surgery. Ten patients with mean age 29.8±8 years, classified as morbidly obese (BMI 47.5±7.2 kg/m 2 ) who received CPAP from 8 to 10 cmH 2 O, for 30 minutes, once a day for two consecutive days, in the post-bariatric surgery were studied. Before and after applying CPAP were measured RR and the MV through the ventilometer, and indirectly the TV were calculated . The Shapito-Wilk was applied to check the normality of data, and then the measures were compared using the Student's t-test and Mann-Whitney test. Analyses were processed using the SPSS 7.5 considering the 5% level of significance. There was a significant increase for the following variables in the first and second days of application: RR=20±6 breathing/min versus 26±7 breathing/min (p=0.009), and RR=22±7 breathing/min versus 26±8 breathing/min (p=0,007); MV=9.57±2.75 L versus 12.39±4.18 L (p=0.041), and MV=9.71±2.52 L versus 11,18±2.96 L (p=0.037). The values of TV=360±157,59 mL versus 440±69,18 mL (p=0,21), and 401±90,46 mL versus 416±78,04 mL (p=0,18) did not differ significantly when comparing pre-and post-application in two days therapy. Thus, it was concluded that CPAP can be applied as an auxiliary respiratory therapy in the treatment of patients in post-bariatric surgery for the RESUMO | O objetivo deste trabalho foi avaliar o efeito da aplicação da pressão positiva contínua nas vias aéreas (CPAP), na frequência respiratória (FR), no volume corrente (VC) e no volume minuto (VM), em pacientes em pós--operatório de cirurgia bariátrica. Foram estudadas dez pacientes com média de idade 29,8±8 anos, classificadas como obesas mórbidas [índice de massa corpórea (IMC) de 47,5±7,2 kg/m 2 ] que receberam CPAP de 8 a 10 cmH 2 O, por 30 minutos, uma vez ao dia, durante dois dias consecutivos, no pós-operatório de cirurgia bariátrica. Antes e após a aplicação da CPAP, foram aferidos a FR e o VM por meio do ventilômetro e, de forma indireta, foi calculado o VC. Para verificar a normalidade dos dados foi aplicado o teste de Shapiro-Wilk, e, após, as medidas foram comparadas com o uso do Teste t de Student e de Man-Whitney. As análises foram processadas com o uso do SPSS 7,5 considerando o nível de 5% de significância. Houve um aumento significativo para as seguintes variáveis estudadas no primeiro e no segundo dia de aplicação: FR=20±6 resp/ min versus 26±7 resp/min (p=0,009) e FR=22±7 resp/ min versus 26±8 resp/min (p=0,007); VM=9,57±2,75 L versus 12,39±4,18 L (p=0,041) e VM=9, 71±2,52 L versus 11,18±2,96 L (p=0,037). Os valores do VC=360±157,59 mL versus 440±69,18 mL (p=0,21) e 401±90,46 mL versus 416±78,04 mL (p=0,18) não apresentaram diferença significativa na comparação pré-e pós-aplicação, nos dois Aplicação da pressão positiva contínua nas vias aéreas em pacientes em pós-operatório de cirurgia bariátrica Applying continuous positive airways pressure in patients...

The clinical consequences of chronic obstructive pulmonary disease (COPD) include fatigue, dyspnea and progressive impairment of exercise capacity. It also produces significant systemic consequences such as nutritional depletion, physical deconditioning, systemic inflammation, and structural and functional changes in the respiratory and locomotor muscles. Regular exercise provides improvements in the health of patients with stable COPD and can relieve the symptoms, increasing the exercise capacity and improving the quality of life, while also reducing hospitalization and, to some extent, the risk of morbidity and mortality. Training with progressive exercises is associated with metabolic and neurohumoral adaptations, heart rate variability, with adaptations in the pulmonary and skeletal muscles, as well as the inflammatory, cardiovascular and respiratory systems. This review will focus on current knowledge of the mechanisms by which physical training can provide beneficial effects in COPD patients. Results: After analyzing the titles, abstracts and content, out of 500 articles found, 489 were excluded, leaving 11 articles. Studies have shown the beneficial effect of aerobic training on COPD. Conclusion: Physical training should be considered a therapeutic option in patients with COPD, regardless of being terrestrial or aquatic, as it can have beneficial effects on the systems.
