Brief Summary:

Background: Although respiratory physiotherapy has been used in patients undergoing cardiac surgery, evidence lacks concerning its effectiveness. The aim of this study was to evaluate the efficacy of three physiotherapeutic protocols used to recover respiratory volumes in the postoperative period.

Methods: Thirty five patients were randomly allocated into three groups. Exercise group (E) was oriented to progressive mobilization. Incentive Spirometry group (IS) performed deep breathings using VoldyneTM, while Breath-Stacking group (BS) performed successive inspiratory efforts using a facial mask adapted to an unidirectional valve. Both BS and IS also performed progressive mobilization. Forced spirometry was carried out in the pre-operative period and from the first to the fifth postoperative day. Statistical analysis used student t-test and ANOVA, and the differences were considered significant when p<0.05.

Arm Intervention/treatment
Active Comparator: Incentive Spirometry
Incentive Spirometry group (IS) was oriented to take a deep breathing through Voldyne 5000TM (Sherwood Medical; St Loius, MO, USA) from Functional Residual Capacity (FRC) to Total Lung Capacity (TLC).
Device: Incentive Spirometry
Incentive Spirometry (IS) has been used extensively in postoperative period and consists of spontaneous deep breaths through a device which provides a visual feedback to maintain a maximum insuflation
Other Name: Voldyne

Active Comparator: Exercise group
Patients were taught huffing (forced expiration while the glottis is opened), supported cough (with patient's hands placed on the sternotomy incision) and mobilization, including active limb exercises, sit out of bed and deambulation (starting on the third postoperative day).
Other: Exercise
Patients were taught huffing (forced expiration while the glottis is opened), supported cough (with patient's hands placed on the sternotomy incision) and mobilization, including active limb exercises, sit out of bed and deambulation (starting on the third postoperative day).
Other Name: Early mobilization

Active Comparator: Breath-Stacking
Breath-Stacking group (BS) performed successive inspiratory efforts using a facial mask adapted to an unidirectional valve
Device: Breath-Stacking Technique
An one-way valve device to promote the summation of successive inspiratory volumes while expiration was avoided
Other Name: One-way inspiratory valve
