What happens when breaths are given to rapidly and the stomach fills with air during CPR?

When breaths are given too rapidly during CPR, air can enter the stomach instead of the lungs, leading to gastric inflation. This can increase intra-abdominal pressure, potentially complicating ventilation and reducing the effectiveness of chest compressions. It may also cause regurgitation, increasing the risk of aspiration. Proper technique and timing of breaths are crucial to avoid these complications.
