Purpose
Although incentive spirometry is commonly used to avoid pulmonary complications in cardiac surgery patients, the breath-stacking technique has been proposed as an alternative to increase pulmonary volumes in the post-operative period.
Objective: To compare inspiratory volume and electromyographic activity of respiratory muscles during breath stacking technique and incentive spirometry in patients undergoing cardiac surgery.

Primary Outcome Measures:
- Inspiratory volume and muscle recruitment during breath-stacking and incentive spirometry techniques in postoperative cardiac patients [ Time Frame: Within 2 days after cardiac surgery ] [ Designated as safety issue: Yes ]
| Enrollment: | 16 |
| Study Start Date: | March 2009 |
| Study Completion Date: | December 2011 |
| Primary Completion Date: | February 2010 (Final data collection date for primary outcome measure) |
| Arms | Assigned Interventions |
|---|---|
| Incentive spirometry |
Behavioral: Breath Stacking
To perform the BS maneuver, a silicone mask containing a one-way valve was attached to the patient's face. Once the mask was adjusted to allow only inspiration (the expiratory branch remained occluded), the patient was asked to make successive inspiratory efforts during 20 seconds.

Detailed Description:
The purpose of the present study are:
- to evaluate and compare the inspiratory volume during the course of Breath Stacking and Incentive Spirometry techniques in patients submitted to myocardial revascularization surgery.
- to compare the electromyographic activity of the scalene, sternocleidomastoid (SCM) and diaphragm muscles during both techniques.

Criteria
Inclusion Criteria:
- patients submitted to myocardial revascularization surgery
Exclusion Criteria:
