Summary

This study looks at whether doing special breathing exercises before heart bypass surgery can help improve oxygen levels afterward. It will include 45 men aged 50 to 60. Some will use an incentive spirometer, some will use an inspiratory muscle trainer, and others will receive standard care. The goal is to see which method works best for faster recovery.
