DO NOT move an infant's head or neck to check for breathing if a spinal injury is suspected. Stop at any time if you feel faint or sick of any kind. Help should arrive soon if they have not already arrived. This is the basic life saving methods, please read over and over again, feel free to practice on a doll, get the techniques right so that you can save a life. Thousands of children and infants choke each day.
Many children die each year from accidents and drowning.
Which means that if CPR was performed in any of these cases, the child, or Adult would have been saved and had a chance to live again. CPR is very important to learn and can be learned at any age, the earlier the better. For your better understanding, I have found a website where you can take an online CPR test to test your knowledge. Go to a Search engine and type in 'CPR online test,' or something of that matter, and you will get great results. Please do not wait to learn CPR, many lives are counting on you.
