What is an expired air resuscitation?

Expired air resuscitation (EAR), also known as mouth-to-mouth resuscitation, is a technique used to provide rescue breathing to a person who has stopped breathing or is breathing inadequately. It involves blowing air into the person's lungs through their mouth or nose.

EAR is a temporary measure to keep the person's vital organs, such as the brain, heart, and lungs, functioning until medical help arrives. Here's a step-by-step guide on how to perform EAR:

1. Check for Responsiveness:

- Gently shake and shout to the person, "Are you okay?"

- If there is no response and they are not breathing or breathing abnormally, proceed with EAR.

2. Open the Airway:

- Place one hand on the person's forehead and two fingers of your other hand on the bony part of their chin.

- Gently tilt the head back to open the airway.

3. Pinch the Nose (for Mouth-to-Mouth):

- Pinch the person's nose closed using your thumb and index finger of the hand that's on the forehead.

4. Take a Deep Breath:

- Inhale deeply to fill your lungs with air.

5. Blow into the Person's Mouth:

- Place your mouth over the person's mouth, creating a seal.

- Blow air into their lungs until you see their chest rise.

- Give two slow breaths, each lasting about one second.

6. Check for Chest Rise and Fall:

- After giving each breath, check if the person's chest rises and falls. If it does, you are successfully providing ventilation.

7. Continue Cycles:

- Alternate between giving two breaths and checking for chest movement.

- Continue these cycles at a rate of approximately 100-120 breaths per minute (about 2 breaths every 3 seconds) until the person starts breathing normally, medical help arrives, or you are exhausted.

8. Consider a Barrier Device:

- If you are uncomfortable giving mouth-to-mouth, consider using a barrier device, such as a CPR face shield or mask, to protect yourself from direct contact with the person's mouth.

Remember, EAR should be used in emergency situations when someone has stopped breathing or is not breathing effectively. It is important to seek professional medical attention as soon as possible. If you are not trained in CPR, consider enrolling in a certified CPR course to learn proper techniques for providing emergency care.
