Final answer:
In case of a casualty that is unconscious and not breathing, the steps to be taken include checking for responsiveness, calling for help, starting CPR, giving rescue breaths, and repeating compressions and breaths until help arrives or the person starts breathing on their own.
Step-by-step explanation:
In case of a casualty that is unconscious and not breathing, the following steps should be taken:
- Check for responsiveness: Shake the person and shout to check if they respond. If there is no response, proceed to the next step.
- Call for help: Call emergency services immediately and provide them with all the necessary information.
- Start CPR: Begin performing cardiopulmonary resuscitation (CPR) by giving chest compressions. Place the heel of one hand on the center of the person's chest, between the nipples, and place the other hand on top. Push hard and fast, aiming for a rate of at least 100 compressions per minute.
- Give rescue breaths: Tilt the person's head back slightly, open their airway by lifting their chin, and give 2 rescue breaths. Watch for chest rise and fall.
- Repeat compressions and breaths: Continue cycles of 30 chest compressions followed by 2 rescue breaths until help arrives or the person starts breathing on their own.
Remember, it is important to learn and receive proper training in CPR to perform it effectively. CPR can significantly increase the chance of survival in an unconscious and not breathing individual.
