My daughter had a similar situation and lost her 2 year old son after taking him to a hospital ER (in another state) 3 times with breathing difficulties, high temps, lethargy, diarrhea, etc.  They refused to admit him, we think probably because she didn't have insurance.  Unfortunately, he passed away the 3rd time she brought him in.  It was determined if he had been admitted and had been given oxygen, he would still be alive today.  Doctors have to make a lot of decisions but it's always better to err on the side of safety.  If they treated patients how they would treat their own family I think there would be a lot better care given.
