Chapter 5: Adult CPR – Airway and Breaths

After 30 compressions:

Open the Airway

• Use the head-tilt, chin-lift technique.
• Tilt the head back slightly.
• Lift the chin.

The tongue is the most common airway obstruction in an unresponsive person.

If you see something clearly blocking the airway and it is easy to remove, remove it. Do not perform blind finger sweeps.

Give Breaths

• Pinch the nose closed.
• Seal your mouth over theirs.
• Give 2 breaths.
• Each breath should last about 1 second.
• Watch for the chest to rise.

If the chest rises, the breath is effective.

If the chest does not rise:

• Reposition the head.
• Try again.
• If still no rise, return immediately to compressions.

Give just enough air to make the chest rise. Avoid giving large or forceful breaths.

Continue 30:2 cycles until:

• An AED is ready
• EMS arrives
• The person begins breathing normally
