Cystic Fibrosis is characterized by excess pulmonary secretions that cause recurrent respiratory infections, with consequent deterioration of gas exchange. Bronchial hygiene techniques aim to mobilize secretions from the peripheral airways so that they can be eliminated by coughing or tracheal aspiration. To identify the effects of different bronchial hygiene techniques on improving lung function in patients with Cystic Fibrosis. Through a systematic review of the literature, randomized controlled trials (RCTs) published between 2007 and 2021 were selected, according to the highest score in the PEDro score. The search involved the PEDro and PubMed databases, using the following keywords: bronchial hygiene. Six ECR`s were included. One study performedthe techniques during anesthesia and observed increased resistance and reduced compliance. Regarding FEV1, 3 RCTs with hospitalized patients showed improvement in lung function, regardless of the technique used. In outpatients, there was no improvement. Regarding secretion weight, the cough machine produced more secretion than autogenous drainage, as well as a drop in saturation after the 2-min walk test, and increased FEV1. Bronchial hygiene techniques in patients with cystic fibrosis have been shown to be effective in removing mucus, with consequent improvement in lung function and aerobic fitness.
