What is the duration of each rescue breath during CPR?

Breath each time should last about 1 second. This pace delivers enough air to inflate the lungs and raise the chest without overinflating, which can cause gastric inflation and increased pressure that hinders blood return to the heart. If breaths are too short, air may not fill the lungs adequately; if they’re too long, you risk overinflation and interrupting chest compressions for too long. In adult CPR, you typically give two breaths after every set of thirty compressions, aiming for roughly a 1-second breath each, whether you’re using mouth-to-mouth, a barrier device, or a bag-mask.
