How should you deliver rescue breaths during CPR with a barrier device?

When delivering rescue breaths with a barrier device, the focus is on ventilating effectively without overinflating the lungs and keeping the heart able to fill between breaths. Each breath should be about 1 second, and you should see the chest rise to confirm the air is entering the lungs. Watching for chest rise is a quick check that you’re providing enough air without risking excessive inflation. Letting the chest recoil fully between breaths is essential because it allows the heart to refill with blood, which helps maintain circulation during CPR. Breaths that are too long can push air into the stomach, causing gastric inflation and vomiting, and they disrupt the CPR flow. Breaths that are too short or too slow don’t ventilate adequately, which limits oxygen delivery. Pausing between breaths isn’t the goal; you want a steady, controlled delivery of about one second per breath with complete chest recoil before the next breath. That combination—one-second breaths, visible chest rise, and full chest recoil between breaths—best supports both oxygenation and circulation during CPR.
