How you and a second rescuer can give CPR to an adult victim together?

Performing CPR as a team of two rescuers can increase its effectiveness and efficiency. Here's a step-by-step guide on how you and a second rescuer can give CPR to an adult victim:

1. Check for Responsiveness:

- Both rescuers should approach the victim and check if they are responsive by gently shaking their shoulders and shouting loudly.

2. Call for Help:

- If the victim is unresponsive, one rescuer should immediately call emergency services (911 or your local emergency number) and provide them with the victim's location and condition.

3. Position the Victim:

- The other rescuer should gently place the victim on their back on a firm, flat surface.

4. Open the Airway:

- The first rescuer should open the victim's airway using the head-tilt/chin-lift maneuver.

5. Check for Breathing:

- Both rescuers should check if the victim is breathing normally for no more than 10 seconds. Look for chest movement and listen for breathing sounds.

6. Give Rescue Breaths:

- If the victim is not breathing or is gasping, the first rescuer should deliver two rescue breaths using the proper technique. Pinch the victim's nose and cover their entire mouth with your mouth, creating an airtight seal. Give two slow, gentle breaths, watching for the victim's chest to rise and fall.

7. Perform Chest Compressions:

- The second rescuer should start chest compressions immediately after the rescue breaths. Position the heel of one hand on the center of the victim's chest, between the nipples. Place the other hand over your first hand, interlocking your fingers. Keep your elbows straight and lock your arms.

- Deliver 30 chest compressions at a rate of 100 to 120 compressions per minute. Press down 3.8 to 5 cm (1.5 to 2 inches) on the chest and allow it to recoil between compressions.

8. Continue CPR Cycles:

- After completing 30 chest compressions, the first rescuer should deliver two more rescue breaths. This completes one cycle of CPR.

- Both rescuers should continue alternating cycles of 30 chest compressions and two rescue breaths until the victim shows signs of life, help arrives, or they become too exhausted to continue.

9. Use an AED (if Available):

- If an automated external defibrillator (AED) is available, the second rescuer should retrieve it as soon as possible and follow the voice prompts. Attach the AED pads to the victim's bare chest as instructed by the device. The AED will analyze the heart rhythm and determine if a shock is needed.

Remember that teamwork is crucial during CPR. Communicating effectively, switching roles periodically to avoid fatigue, and maintaining focus can significantly improve the chances of successful resuscitation.
