Rescue Breathing Timing: Duration and Pauses for Effective Ventilation

For rescue breathing (mouth-to-mouth or bag-mask):

  • Each breath: Deliver over ~1 second.
  • Pause between breaths: ~5 seconds (allows chest fall, prevents hyperventilation).
  • Rate: ~10–12 breaths/minute (adults); 12–20 (children/infants).

Watch for chest rise. Avoid excessive volume/pressure. In CPR, ratio is 30 compressions : 2 breaths (single rescuer).
