I had to perform CPR on an elderly bloke a couple of days ago, I snapped 2 ribs on the first compression and another 1 on the next compression. When the Medics arrived I told them I had broken 3 ribs on the bloke, they said no problems and asked me to carry on for a minute while they got their magic kit set up. Today I've been visited by 2 relatives of the bloke (he died in hospital)who heard what I said to the Medic and are saying that if I hadn't assaulted him and broke his ribs he would still be alive. I feel that they are looking for compensation. As the Law stands, have I " assaulted " the bloke by doing CPR ? Any advice appreciated.
