Basic of first-aid for workers of child care

What are the principles of the basic of first-aid for workers of child care:

• As we mentioned earlier, the absolute quiet, the assessment of the situation, and making sure there's no any danger to you or the injured child.
• Check the responding of the child to know if he is conscious or unconscious.
• Make sure that the airlock is opened, then check the breath, and begin to behave according to the case.
• Treat every injury, reassure and follow-up the child, that if the injured child is more than two years old, but if a baby, it's enough to put him on his back and follow-up it.
• Check the circulatory and check the fundamental signs of life like: coughing, movement and the breath and examine it every minute.
• If the child is not breathing, you should use the artificial respiration immediately, by the chest compressions, with putting the lips around the mouth of the baby and inserting the breath into the mouth of the baby regularly until his chest rises, and after five times of the chest compressions, give him an one artificial respiration.
• Asphyxia of the baby is too easy, by the food or putting small things in his mouth, in this case, you should remove any air embolism with your right set of mammary glands, if that fails, put the baby on his back and pressure to the sternum which is under the line between the nipples by two fingers only and continue to do this operation until the ambulance arrives.
