How do you get rid of gas buildup in chest after heart surgery four days ago?

Try yogurt: You had heart surgery 4 days ago. You were given antibiotics during the surgery so you can try yogurt to return your normal gut flora. Also walk a lot every day to move the gas along. If you are taking pain killers try to also take a stool softener.

It depends: If there is a significant amount of air in the chest and it is causing a problem, it can be removed by placing a catheter or tube in the chest. The doctors will help make this decision.
