How to Give Effective Rescue Breaths

If you are a trained rescuer and willing to deliver rescue breaths, then perform two rescue breaths after each set of thirty compressions. Continue this cycle of thirty chest compressions to two rescue breaths.

1. Open the victim's airway by tilting the head backward.

2. Pinch the nose to prevent air leaking out.

3. Take a regular breath and make a seal over the victim's mouth, using a disposable resuscitation face shield if available.

4. Breathe into the victim's mouth for approximately one second; do not overinflate the victim's lungs as this could cause air to go into the stomach and the victim to vomit.

5. Deliver two rescue breath attempts in total, then immediately resume chest compressions.

If two trained rescuers are present, one can perform chest compressions, and the other deliver rescue breaths, still at a ratio of thirty chest compressions to two rescue breaths. This twoperson technique minimizes any interruptions in chest compressions.

How to Give Effective Rescue Breaths

Pinch the victim's nose and tilt the head backward to deliver effective rescue breaths.

Continue providing CPR (either chest compressions only, or chest compressions with rescue breaths) until the arrival of a defibrillator or emergency medical help. If a defibrillator is available, attach it to the victim and follow the instructions (see Using an Automated External Defibrillator later in this chapter). When EMS arrives, they may ask you to assist by continuing chest compressions while they perform advanced medical interventions.

The victim may vomit when you are performing CPR. If this happens, don't panic. It does not mean that you've done anything incorrectly. As we saw in the previous section, an unconscious victim can lose control of his stomach contents and may vomit. If the victim vomits when you are performing CPR, turn him onto his side to allow the vomit to drain away from the airway. Then turn him back and resume CPR as quickly as possible.

When to Stop CPR

CPR needs to be performed continuously for it to be effective. Stop CPR only if:

◾ The victim shows signs of life and is breathing normally.

◾ EMS arrives and asks you to stop.

◾ The environment becomes too unsafe for you to remain on scene, and you cannot safely move the victim.

◾ You become physically exhausted and unable to continue.

Remember you are the most important person in any emergency situation. If you become exhausted and bystanders are present, show them how to perform chest compressions so they can take over.
