If the scene is safe and CPR is needed, place the victim on his/her back with the chest facing upwards on a hard surface, such as the floor or ground. Do not use a soft surface like a mattress. This will allow the rescuer to start compressions if needed.
Checking for a pulse should take at least 5 seconds, but no longer than 10 seconds.
Infants: Check an infant's pulse at the brachial artery located in the center of the inner, upper arm.
Children (Ages 1-8): Check a child's pulse at the femoral artery located in the inner thigh between the hip bone and pubic bone.
Stay in the know & keep your finger on the pulse!
