You can ask questions here that you have encountered in learning CPR and AED theory or in practical exercises.

📌Examples:

"The position of the hand during CPR compressions is always wrong, what are the techniques to correct it?"

"When AED analyses the heart rhythm, will someone walking next to me affect the results?"

If you have experience in CPR or AED operation (including simulation drills and real scenarios), you can describe here the difficulties you encountered during the process, the measures you took to cope with them, and the insights you gained from them.

📌Example:

In a CPR simulation exercise organized by the school, the rhythm of my first compressions was particularly fast, and I was able to adjust it later by reciting the mnemonic, so you can also try this method.

You can share stories about CPR and AED that they have heard or experienced.

📌Example:

I heard that an old man in the next community suffered a cardiac arrest. Fortunately, someone next to him had learnt CPR and was able to save him in time, which made me realize the importance of having first aid skills.

I hope you can summarise in this section the precautions you have learned in your studies and practice.

📌Example：

"Make sure the patient's chest is dry before using the AED, or the fit of the electrode pads and the shock effect may be affected."

As in Scratch, there are always sound to remind us to call "911"

1. Make sure the surroundings are safe.

2. Shake the patient's shoulder to ask for responses.

3. Shout for others to help.

4. Clear the patient's airway.

5. Listen to and observe the patient's breath for 10 seconds.

6. Callthe ambulance

7. Press chest around 2 times every second, chest down 5 cm deep

8. 2 rescue breaths after every 30 compressions (if trained before)

Rate: 100–120 compressions per minute.

Depth: At least 2 inches (5 cm) for adults; ⅓ of the chest depth for children/infants.

Technique: Push hard and fast, allowing full chest recoil between compressions.

Turn on the AED and follow its voice prompts. Place pads on the chest as shown on the device. Ensure no one touches the patient during analysis or shock. Press the shock button if advised. Start CPR immediately after, and repeat until help arrives or signs of life appear.

1. Check Responsiveness

   • Tap & shout, "Are you okay?"

2. Call for Help

   • Yell for assistance or call 911 (or local emergency number).

   • Get an AED if available.

3. Start Chest Compressions

   • Push hard & fast (100–120/min) on the center of the chest.

   • Depth: 2 inches (5 cm) for adults.

4. Rescue Breaths (If Trained)

   • After 30 compressions, give 2 breaths (tilt head, pinch nose).

5. Use AED (If Available)

   • Follow voice prompts—shock if advised.

6. Continue CPR

   • Repeat until help arrives or person wakes up.
