I had a 911 call and there was a child bleeding heavily and was short of breath. His mother was screaming and crying and scared. So, when I got the call the 9-1-1 service told me the mother needs to calm down.
She needed to follow the instructions while the ambulance reaches her residence. Those instructions included a way to stop the heavy bleeding and administer CPR.
It took some time and lots of repeating of the instructions but, finally, the mother said the child opened his eyes and the bleeding had subsided.
Our 911 client and I were very, very happy and the client kept telling me how good I did and that we saved a life. It made me feel very good about myself. I love my job because every call I take I am making a difference.
