What is indicated when a rescuer gives too many rescue breaths too quickly or breaths that are too large?

The correct answer is excessive ventilation. When a rescuer delivers too many breaths in a short period or uses breaths that are excessively large, it can lead to an increased volume of air being introduced into the lungs. This can have serious implications, including causing the person to vomit or inflate the stomach, which can obstruct the airway and complicate further rescue efforts.

Excessive ventilation can also impair blood flow and reduce the effectiveness of oxygenation, as it may lead to hyperventilation, which can alter the carbon dioxide levels in the blood. It’s crucial for rescuers to deliver rescue breaths at a safe and effective rate and volume to ensure adequate and efficient oxygenation without causing additional complications.

The focus on managing the volume and frequency of breaths is vital in maintaining the balance of oxygen and carbon dioxide during resuscitation efforts.
