One thing with CVA's. Don't get stuck on the "3 hour" time window.
Most stroke centers have multiple treatments available. They can go up to 16 hours out. You need to find out from your local stroke center, what they have available.
the reason i say "3 hours" is that it is our protocol. after working with our stroke centers, the state made our goal to get the patient there in under 3 hours.
not disagreeing with you... just explaining that that window is what our protocol says.
