You give 2 breaths after every 30 compressions on an adult when doing CPR with rescue breaths (the standard ratio is 30:2).

Quick Scoop

  • Compression‑to‑breath ratio for adults: 30 compressions, then 2 breaths.
  • Keep compression rate at about 100–120 per minute and minimize pauses for breaths.
  • Many guidelines also say that if you are untrained or uncomfortable giving breaths, doing hands‑only CPR (just compressions) is still much better than doing nothing.

Always follow the latest local CPR training you received, as official guidance can be updated over time.
