Had a 84 y/o f fall. On route to call location (VFD) call was cancelled by security (private community). Security cannot cancell call. Anyways, just recently completed EMT course and NREMT pass. Show up to scene to find pt laying on floor by couch (laying on pillows by couch) waiting for ambulance to arrive. Non friendly security officer questions why I am there and he cancelled call (also vfd member). I stood there like a jackass and did nothing. This after standing outside wondering what I should do (wait for ambulance, or check on pt). Should I have gone in medical bag on shoulder and either requested vitals, or perfomed vitals myself? PT not in obvious pain, alert but did not ask AVPU, talking, breathing and in no obvious distress. Helped load and ended call. Should I have done more? I should have at least secured good vitals to make sure of no internal bleeding or possible shock?
