A. The paramedics in the ambulance aren’t going to do anything to treat a stroke.
B. Calling 911 and getting an ambulance takes time. A stroke is one of the few times when minutes count.
C. The cop should have backed off once it was clear there was a medical emergency ( guy carrying his wife into the ER ). He can site the guy later.
Speaking as an ER doc who was an EMS medical director in a good sized city.
If a blood clot is the cause, ‘clot busting’ medication may be used to dissolve the clot, but this must be given within three hours of the stroke. Anti-clotting medication such as aspirin may also be given to stop the stroke from getting worse.
Anti-clotting medication is not given in strokes caused by haemorrhaging because it will make the bleeding worse.
Be prepared to waste lots of time if you speed and / or blow red lights. If that’s acceptable, then OK.
