The purpose of bls rp is not meant to be the most detailed medical treatment that fully fixes you. Its only meant to stabilize you long enough to get you to the hospital where you RPLY are treated by ER staff when the script revives you at the hospital.
If you think someone did in fact power game with their RP or /cpr before adequately RPing any treatment or Rping treatment at all then report it. But you also need to be realistic. This is a video game, we aren't going to expect players to know exactly what to type to RP out treating traumatic injuries all we can expect is a good faith effort to put something that at least somewhat makes sense.
