Some Background - Updated June 1st

Note: The account below has been corrected with additional information that has come to light from accounts of the accident site, from colleagues who were with Dad shortly before his last bike ride, and from my visit to the site of the accident.

To fill everyone in on some background on the events of Friday afternoon (May 26th):

• Dad was struck by a black SUV while bicycling on Soil Conservation Road.
  
• Dad was found unconscious on the road.
  

• Emergency services arrived on the scene quickly, and he was taken by helicopter to Prince Georges Hospital Center just outside Greenbelt, MD. Dad's colleagues, Ilan and Vanderlei, estimate that he was in the ER within 20 minutes of the accident.
  
• He was unconscious upon arrival. At this point, he was rated a 6 on the Glascow Coma Scale (GCS).
• 1-2 hours after arriving, Dad regained consciousness. He responded to directions from the medical staff. His GCS was upgraded to "8-10" - which is almost as high as someone can get when they are intubated. Mom held his hand and he squeezed her hand. She thanked him and told him she loved him. He squeezed again.
• That night, a special "bolt" was installed in his head to measure his Intracanial Pressure (ICP). Whereas normal ICP is about 5 mmHg, he peaked around 45.
