When giving rescue breaths make sure to avoid?

When giving rescue breaths, make sure to avoid over-inflating the lungs, as this can lead to complications such as gastric inflation and reduced effectiveness of the breaths. Additionally, ensure that the airway is properly positioned to maintain an open passage, and avoid giving breaths too quickly; each breath should be delivered slowly and steadily. It's also crucial to avoid any interruptions in chest compressions during CPR, as this can decrease blood flow to vital organs.
