I think the difference is now you start with chest compressions instead of breaths.
There is also a bit of a difference in how you handle children vs. adults. Older adults is more of a presumption that it is a heart issue, where with kids it is more likely a respiratory or choking problem (as was the case for Geico's patient). It is likely this child's heart didn't completely stop, but the pulse was so weak it couldn't be felt.
I've been trained on CPR since high school, and current almost continuously. The training keeps evolving but most of the differences matter little in practice except to pass the test (this is according to some of my instructors). Keeping the airway open is the hardest part, and I doubt the simulations with Annie really prepare you for what you'll deal with, having never handled anything past a simple choking situation with a child that they were able to clear with the "just keep coughing" prompts.
