Question: 1 / 400

For how long should each breath be delivered during rescue breathing?

0.5 seconds

1 second

Delivering each breath during rescue breathing for 1 second is essential because it allows sufficient time for the air to enter the lungs while also minimizing the risk of causing air to enter the stomach, which can happen if breaths are delivered too quickly. This timing helps ensure that the chest visibly rises, indicating that the breath is being effectively delivered into the lungs. By providing a breath duration of 1 second, rescuers can maintain a steady rhythm during the process of ventilation, enhancing the effectiveness of oxygen delivery to the person's lungs. This approach aligns with CPR guidelines, ensuring the best possible outcomes during emergencies involving respiratory failure.
