Comparison of Lung Function in Post-CABG Patients Administered Supervised and Non-supervised Post-operative Incentive Spirometry: a Quasi-experimental Study
In Brief
A clinical study evaluating Supervised Incentive Spirometry (SIS) and Non-Supervised Incentive Spirometry (Non-SIS) for Postoperative Pulmonary Function Impairment. Completed, enrolled 38 participants across 1 site.
Detailed Summary
This study aims to evaluate the effect of supervised incentive spirometry (SIS) compared to unsupervised incentive spirometry (Non-SIS) on pulmonary function in patients following coronary artery bypass graft (CABG) surgery. Participants perform incentive spirometry exercises twice daily for three days after extubation. Pulmonary function parameters, including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF), are assessed before and after the intervention period to compare changes between the two groups.
Study Details
Timeline
Interventions
Participants perform incentive spirometry exercises twice daily for 3 days under direct supervision. The supervisor monitors technique, corrects errors, answers questions, and ensures exercises are done accurately. Each session includes 6 sets of 5 breaths, with slow inhalation, 2-second breath-hold, and slow exhalation, separated by rest periods. This intervention is performed in addition to standard cardiac rehabilitation.
Exercises independently using a guideline form with daily reminders. Participants log activity. 6 sets of 5 breaths per session.
