Final answer:
If you encounter a victim with no normal breathing and no pulse, you should immediately start performing CPR until help arrives or an AED becomes available. Follow these steps: call for medical help, perform chest compressions at a rate of 100-120 per minute, and consider adding rescue breaths after every 30 compressions.
Step-by-step explanation:
If you come across a victim with no normal breathing and no pulse, it is crucial to act quickly and provide Basic Life Support (BLS) which includes performing CPR (Cardiopulmonary Resuscitation). Here are the steps to follow:
- Call for emergency medical help or ask someone nearby to do so.
- Begin chest compressions. Place the heel of one hand on the center of the victim's chest, between the nipples, and place the other hand on top. Push hard and fast, aiming for a depth of at least 5 centimeters (about 2 inches) at a rate of 100-120 compressions per minute.
- If you are trained in CPR, you can also give rescue breaths after every 30 chest compressions. Tilt the victim's head back and pinch their nose. Create a seal over their mouth with yours and give 2 breaths, each lasting about 1 second.
- Continue performing cycles of chest compressions and rescue breaths until help arrives or an automated external defibrillator (AED) becomes available.
