RedactedNarrative: At approximately 0945 hrs, Wasatch County dispatch to the main Marina courtesy docks for a possible stroke victim.  It was reported that an elderly male, 91 years old may have suffered a stroke.  Dispatch stated that he was in a small red fishing boat, conscious but unresponsive and that they were heading to the docks.  I was at the top of the ramp at the time of the call so I informed dispatch that I would also respond and that I was already at the ramp.  I drove down to the courtesy dock and saw an elderly man surrounded by two people that were giving him care in a small red fishing boat.  
  
  I noticed that his head was slumped into his chest but that he was moving his head a little.  At this time another officer arrived with his jump pack while I grabbed my O2 tank.  We arrived at the victim who was still conscious but mostly unresponsive and disorientated.  I applied O2 via a non-rebreather mask at a setting of 15.  officer kept soliciting a response from VICTIM.  After several minutes on O2, VICTIM started to respond to verbal commands and become more coherent.  Jordanelle Ambulance marrived and took over care of VICTIM.  VICTIM become progressively more coherent over time.  VICTIM was loaded onto the ambulance and taken to Park City Medical.
  
  OBSERVATIONS:
  VICTIM was 91 years old and was wearing a life jacket at the time of this incident.  It was becoming very hot and a little humid due to the lack of any significant breeze at the time.  When VICTIM took of his life jacket, he was soaked in perspiration.  VICTIM was also wearing his life jacket very tight.  It was possible that VICTIM became somewhat de-hydrated and suffered from some sort of heat stress.
