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.

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.

Conditions

• Functional Disturbance Following Cardiac Surgery

Interventions

Type	Name	Description
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.
