Respiratory Physiotherapy After Cardiac Surgery

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

patients submitted to myocardial revascularization surgery

Exclusion criteria

cognitive impairment or incoordination to perform IS
face mask intolerance during BS
level of consciousness incompatible to perform IS
hemodynamic complications [arrhythmia, intraoperative myocardial infarction, major blood loss (defined as a loss of ≥20% of total blood volume), mean arterial pressure <70 mmHg and reduce cardiac output requiring the use of an intra-aortic balloon pump or vasoactive drugs)
intubation for more than 72 h after admission to the Intensive Care Unit
the need for reintubation.

Treatment and study plan

Breath Stacking

Behavioral

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 names: respiratory exercises
