Basic Life Support (BLS) Practice Exam

During CPR for a child or infant with an advanced airway, how often should one provider deliver ventilations?

1. Every 30 seconds

2. Every 2 to 3 seconds

3. Continuous ventilations

4. Once every minute

The correct answer is: Every 2 to 3 seconds

In the context of providing CPR for a child or infant with an advanced airway, the correct practice involves delivering ventilations every 2 to 3 seconds. This recommendation is based on the need to ensure that effective breaths are being provided to the child or infant without compromising the quality of chest compressions. When an advanced airway is utilized, continuous chest compressions can be administered, and the timing of ventilations is adjusted to this protocol. Delivering a breath every 2 to 3 seconds aligns with the goal of maintaining a proper ratio of ventilation to circulation, ensuring that the child receives adequate oxygen while also prioritizing effective chest compressions. Other timing options, such as every 30 seconds or once every minute, would not support the physiological needs of the child during CPR. Additionally, continuous ventilations would not provide effective support in a scenario where chest compressions are critical for maintaining circulation. Therefore, establishing a rhythm of ventilations every 2 to 3 seconds is essential for optimal resuscitation outcomes in this age group.
