Functional Disturbance Following Cardiac Surgery Clinical Trial
Official title:
Inspiratory Volume and Muscle Recruitment During Breath-stacking and Incentive Spirometry Techniques in Postoperative Cardiac Patients
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.
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.
