How will you perform CPR on an unresponsive man with no signs of life?

Performing CPR (Cardiopulmonary Resuscitation) on an unresponsive man with no signs of life requires quick action and proper technique. Here's a step-by-step guide on how to perform CPR:

1. Check for Responsiveness:

- Tap the person's shoulder and shout, "Are you okay?"

- If there is no response, the person is unresponsive and needs CPR.

2. Call for Help:

- If someone else is present, ask them to call emergency services (911 or local emergency number) immediately.

- If you are alone, call for help first, then return to the person and start CPR.

3. Position the Person:

- Lay the person on their back on a firm, flat surface.

- Ensure their airway is clear by gently tilting their head back and lifting their chin.

4. Check for Breathing:

- Look, listen, and feel for normal breathing for no more than 10 seconds.

- If the person is not breathing or is gasping for air, begin CPR.

5. Start Chest Compressions:

- Position your hands on the person's chest, with one hand on top of the other and fingers interlocked.

- Place the heel of your bottom hand on the person's sternum, between the nipples.

- Use your body weight to deliver chest compressions by pushing down firmly and allowing the chest to recoil.

- Aim for a rate of approximately 100-120 compressions per minute.

- Push down 3.8 to 5 centimeters (1.5 to 2 inches) on the chest.

- Allow the chest to fully recoil between compressions.

6. Give Rescue Breaths:

- After every 30 compressions, open the person's airway by tilting their head back and lifting their chin.

- Pinch their nose shut and give two rescue breaths.

- Watch for the chest to rise and fall with each breath.

- Each breath should last about 1 second.

7. Continue CPR Cycles:

- Perform 30 compressions followed by 2 rescue breaths.

- Continue this cycle until:

- The person starts showing signs of life (e.g., coughing, breathing, or moving).

- Trained medical personnel arrive and take over.

- You become too exhausted to continue.

8. Use an AED (Automated External Defibrillator):

- If an AED is available, turn it on and follow the voice prompts.

- Attach the electrode pads according to the instructions provided with the AED.

- The AED will analyze the person's heart rhythm and determine if a shock is necessary.

- If a shock is advised, the AED will instruct you when to stand clear before delivering the shock.

9. Continue CPR Until Help Arrives:

- Continue performing CPR until trained medical professionals arrive and take over.

10. Seek Medical Attention:

- If the person regains consciousness, monitor them closely for any changes until emergency medical personnel arrive.

- Always seek professional medical attention, even if the person appears to recover after CPR.

Remember, proper training and certification in CPR and AED usage can greatly improve the chances of a successful outcome in an emergency situation.
