How often should rescue breaths be given for an adult during CPR?

During CPR for an adult, rescue breaths should be administered approximately every 5 to 6 seconds, which means delivering a breath roughly every 5 seconds is consistent with recommended guidelines. Each rescue breath should take about 1 second, allowing enough time for the chest to rise visibly, indicating effective ventilation. Providing breaths too quickly can lead to inadequate ventilation and increase the risk of air entering the stomach rather than the lungs, which can cause other complications. Therefore, the aim is to maintain a balanced approach, ensuring sufficient oxygenation while avoiding potential hazards associated with rapid breaths. This is why giving rescue breaths every 5 seconds is vital for effective CPR.
