Are illegal immigrants flooding the Emergency Rooms in the US?

No. Anyone in the medical field has always known illegal immigrants are not the problem. Everything your article says if true and 30% of those I observed when I worked at the hospital in Cali used an ambulance for those non-emergency visits to the ER paid for by the taxpayers. Part of the problem in my opinion is the parents that have no idea when they should take the child to the ER or even to the Doctors office. I am not talking brain surgery here, just how to get a fever down or when a fever is dangerous.
