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||Phase|
|Functional Disturbance Following Cardiac Surgery||Behavioral: Breath Stacking||Not Applicable|
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.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||16 participants|
|Intervention Model:||Crossover Assignment|
|Masking:||None (Open Label)|
|Official Title:||Inspiratory Volume and Muscle Recruitment During Breath-stacking and Incentive Spirometry Techniques in Postoperative Cardiac Patients|
|Study Start Date :||March 2009|
|Actual Primary Completion Date :||February 2010|
|Actual Study Completion Date :||December 2011|
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.
