What is considered effective rescue breathing for adults?

Effective rescue breathing for adults involves providing 2 breaths, each lasting about 1 second, while ensuring that the chest rises visibly. This technique is crucial because the goal of rescue breathing is to provide adequate oxygen to the lungs, which in turn helps to supply oxygen to the body’s vital organs.

When administering breaths, the timing is important; each breath should be delivered over approximately 1 second to allow for proper inflation of the lungs without forcing air too quickly, which could lead to complications such as air entering the stomach rather than the lungs. Observing the chest rise is essential as it confirms that air is being effectively delivered. Adequate chest rise indicates that the breaths are being effective and oxygen is reaching the lungs.

The other choices propose methods that either deliver breaths inappropriately or do not adhere to established guidelines for rescue breathing in adults. The structured approach of delivering 2 breaths is aligned with CPR standards and ensures that the rescuer consistently monitors the effectiveness of their actions.
