Objective: To evaluate effectiveness of positive expiratory pressure blow-bottle device compared to expiratory positive airway pressure and conventional physiotherapy on pulmonary function in postoperative cardiac surgery patients in intensive care unit.
Design: A randomized controlled trial.
Settings: Tertiary care.
Objective: The benefits of inspiratory muscle training (IMT) have already been demonstrated in patients with heart failure (HF), but the best mode of training and which patients benefit from this intervention are not clear. The purpose of this study was to review the effects of IMT on respiratory muscle strength, functional capacity, pulmonary function, quality of life, and dyspnea in patients with HF; IMT isolated or combined with another intervention (combined IMT), the presence of inspiratory muscle weakness, training load, and intervention time were considered.
Methods: The search included the databases MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and LILACS database through September 2019.
