Hey I've been a CNA for about 4 yrs. working in long term care. I work 3-11 and I was making my last round at about 10:15p, when I walked into a pts. room to provide care to him. I called his name but he didn't answer so I walked to his bed to see that he wasn't breathing. I also listened for breathing and checked his pulse and got NO response. My first thought was FULL CODE or DNR I usually have this memorized but he was a new pt. so I wasnt at all sure. So I screamed into the hall for the charge nurse....no one came. So I had to make a QUICK decision...look for the nurse or try to save this man's life. So I ran to the Nurses station pulled his chart and saw "FULL CODE" in red letters. I picked up the intercom but couldn't use it because someone at another nurses station hadn't hang it up from the last page. So I sprinted down to the pts. room with the crash cart, turned on the call light and dragged him onto the floor and started CPR I was screaming into the hall during the chest compressions, about 2 mins later another CNA ran into the room, I screamed go and get the nurse. In about 30 sec later every nurse and CNA in the building was in the room. My charge nurse took over, his oxygen level got up to 94 and EMS came and took him away. He later died at the hosp. But that next morning I was called into the DON's office for what I thought was gonna be a "good job" speech but she actually wrote me up for "not following protocol" she explained to me that I should went and found the nurse before I took matters into my own hands. I explained to her that I could NOT find anyone and I also couldn't page because of the intercom malfunction. I'm CPR certified so thats why I did what I did.....was I wrong what is the protocol at other facilities PLEASE let me know.
