The objective of this study is to investigate the effects of a program of early mobilization in the functional capacity in patients undergoing coronary artery bypass grafting in short and long- term.
The hypotheses this study is that patients if conduct the program of early mobilization during hospitalization achieve better performance in the walk test (distance) at hospital discharge and 60 days after the surgical procedure compared to patients who only carry out the program of respiratory exercises. Intervention and control groups will receive breathing exercises up to 24 hours postoperatively, and the intervention group will also receive early mobilization exercises.

Respiratory exercises will be performed and subsequently active upper limb exercises will be conducted (flexion-extension and adduction-abduction) of large joints (shoulder, elbow and wrist) Associated with upper limb exercises, patients will undergo a series of exercises ergometer with lower limb (LL). The mobilization will be conducted on a cycle ergometer in an active, lasting 20 minutes, divided into three steps: heat 5 minutes; 10 minutes of low intensity exercise, with a speed of 30 revolutions per minute (rpm); and 5 minutes recovery. The patient remains in the supine position with the head of the bed elevated to 45 degrees, while the lower limbs will remain planned. After positioning the patient, the ergometer is adjusted.
The patients will oriented to maintain sitting position and perform deep breaths (3 sets of 10 repetitions) in each session. They will receive the intervention once a day, for 30 minutes until 7th postoperative day. In addition, non invasive ventilation will be installed after orotracheal extubation for 30 to 60 minutes.
Functional Capacity
Patients will be submitted to six minute walking test
Time frame: All patients will be evaluated on preoperative period ( when they arrived in the hospital to do the surgery), hospital discharge ( about a mean of two weeks afeter surgery) and 60 postoperative days in cargiology ambulatory
Intensive Care Unit (ICU) and Hospital length of stay
The number the days in ICU and hospital until discharge will be counted for each patient
Time frame: All patients will be followed for the duration of hospital stay, an expected average of 30 days
Postoperative pulmonary complication (PPC)
The occurrence of PPC will be monitored until the day of hospital discharge by a physician blinded to the groups: pneumonia (chest radiography with pulmonary infiltrate associated with two of the following signs: purulent expectoration, temperature above 38.3º C and a greater than 25% increase in baseline leukocyte count with hyperthermia), atelectasis (RS associated with abnormal chest acute respiratory symptoms), hypoxemia (peripheral oxygen saturation associated with respiratory symptoms below 85%).
Time frame: All patients will be followed for the duration of hospital stay, an expected average of 30 days
