Brief Summary:

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.


Condition or disease Intervention/treatment
Functional Disturbance Following Cardiac Surgery Behavioral: Breath Stacking

Detailed Description:

The purpose of the present study are:

  1. to evaluate and compare the inspiratory volume during the course of Breath Stacking and Incentive Spirometry techniques in patients submitted to myocardial revascularization surgery.
  2. to compare the electromyographic activity of the scalene, sternocleidomastoid (SCM) and diaphragm muscles during both techniques.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 16 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Inspiratory Volume and Muscle Recruitment During Breath-stacking and Incentive Spirometry Techniques in Postoperative Cardiac Patients
Study Start Date : March 2009

Arm Intervention/treatment
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.
Other Name: respiratory exercises
No Intervention: Breath Stacking



Primary Outcome Measures :
  1. Inspiratory volume and muscle recruitment during breath-stacking and incentive spirometry techniques in postoperative cardiac patients [ Time Frame: Within 2 days after cardiac surgery ]
