Having sat in an emergency room with a BOC under 95% for a couple hours while the ER staff saw a grand total of two patients I can believe this happened.
After going through an entire albuterol inhaler (NOT recommended practice, but it was either that or pass out)and getting my lungs back to a functioning state, I left, called my doc, got a refill on the scrip and another scrip to assist, and wrote a letter to the hospital admin, return receipt requested. Got the receipt back, but never a response from the hospital.
Yes, I can believe it, and I can also believe that the hospital staff didn't care a damned bit.
