Rescue Breathing Steps

Tilt the Head

What to Do:

Lay the patient flat on his back and tilt his head with one hand on his forehead and your other hand on his chin.

What You're Doing:

By tilting the patient's head back, you're straightening out the trachea *windpipe" and opening it up for more airflow. If there is anything blocking airflow in the trachea, this should help alleviate the blockage.

Cover the Mouth and Breathe

What to Do:

Cover the patient's mouth with your mouth. Make a seal and blow just enough air to make the patient's chest rise.

What You're Doing:

The air you exhale isn't perfect, but it does have enough oxygen to help someone live.

What to Do:

If you're performing CPR, do a second breath and then push on the chest 30 times.

If you're giving mouth to mouth to a patient who is not in cardiac arrest (their heart is still beating), then just keep giving rescue breaths until someone arrives to help. If you didn't call 911, go ahead and do it now.

What You're Doing:

Blowing air from one person into the mouth or nose of another to inflate the recipient's lungs. Rescue breathing is often used as a compliment to chest compressions during cardiopulmonary resuscitation.

When we breathe naturally, we expand the size of our chests by pushing the diaphragm down and contracting the muscles around the rib cage. Our chests get bigger, creating negative pressure inside and air rushes in, filling the lungs.

The negative pressure also encourages blood to return to the chest.

Rescue breathing, by pushing air in, actually inhibits blood returning to the heart. Rescue breathing is important for patients who are not breathing, but still have a heartbeat. In most cases, rescue breathing is only recommended to be performed by lay rescuers in certain cases. The next slides show how to perform rescue breathing.

By adding rescue breaths to your CPR treatment, you are possibly increasing the patient's chance of survival. There isn't any definitive research on the benefits of mouth to mouth, but plenty of anecdotes suggest that rescue breathing helps save lives.
