“…11 Previously, it has been shown that, in chronic cardiopulmonary diseases, noninvasive ventilation associated with exercise is able to unload respiratory muscles, reduce dyspnea, and improve exercise tolerance. [28][29][30] In this context, we demonstrated CPAP, in conjunction with exercise, after CABG improves outcome measurements in the inpatient setting after the surgical procedure, which is a new application for this adjunctive intervention.…”

“…The percent rib cage inspiratory (%RCi) and expiratory contribution to tidal volume (%RCe), relative to thoracoabdominal coordination, were also used and were obtained from the ratio of the inspiratory or expiratory volume related to the thoracic compartment by total tidal volume (the sum of the thoracic and abdominal compartments), at the peak of inspiration or expiration. 11 Thus, the primary outcomes of this study were ET s for walking, dyspnea scores, evaluated by the Borg category-ratio scale CR-10, and SpO 2 after exercise. The secondary outcome measures were represented by the breathing pattern variables.…”

“…9 Ambas as técnicas possuem benefícios semelhantes e têm se mostrado efetivas em diversas condições terapêu-ticas. 10,11,12 Em geral essas modalidades se diferem quanto ao fornecimento de pressão gerada por cada componente, para RPPI utiliza-se 10 a 30 cm/ H 2 O 12,13 e para CPAP pode variar de 4 a 10 cm/ H 2 O 8,9,14,15 , entretanto, estudos recentes mostrando os efeitos benéficos de níveis maiores de CPAP 16,17 e de RPPI 1 são descritos na literatura.…”
