Clinical Trial Summary

This study evaluates the efficacy and safety of a single session of positive expiratory pressure and of breath stacking technique in patients after cardiac surgery. The same patients will receive the two interventions, with an interval of 24 hours, and the acute effect of each will be verifed.


Clinical Trial Description

Physiotherapy uses techniques and equipment that reduce postoperative pulmonary complications. The technique called breath stacking consists of an instrumental feature composed of a unidirectional valve coupled to a face mask to promote the accumulation of successive inspiratory volumes. The technique is used to prevent atelectasis and improve gas exchange. Another therapy is called expiratory positive airway pressure (EPAP) that uses positive end expiratory pressure (PEEP) in spontaneously breathing patients, keeping the airway open during expiration. The EPAP system consists of a face mask, a one-way valve and the expiratory resistor, which is responsible for resistance to expiratory flow, which will determine the level of PEEP. ;
