Hospital calls 911?

What in the hell is going on out there? Apparently at a small hospital in Texas Steve Spivey was recovering from spinal surgery when he began to have problems breathing. There was no doctors currently at the hospital. As Steve's wife Tracy desperately tried to get staff to contact a doctor, she began CPR on her husband since no one else was. It was sometime in her 15 minutes of CPR that she heard someone call 911. Most articles I found regarding this don't make mention of the staff also calling the hospital surgeon back, but I found a few publications that quoted the Spivey lawyer as stating they did so. I was unable to find any reference as to his arrival or how far away he was when contacted.

Emergency crews were dispatched after the 911 call and an air tube was inserted before transport of Mr. Spivey. However upon arrival at a fully staffed hospital he was pronounced dead. So I ask again, how in the world can hospitals exist without a doctor on site at all times. Or at the minimum, have well trained staff on hand that are capable of stabilizing patients until further help can arrive. I find it simply unbelievable that a hospital can exist without one or the other. That's just asking for something like this to happen. Common sense folks, people sometimes have complications after surgery, either be prepared to handle that, or don't perform the surgery.
