Key PointsKey Points
EMS play a EMS play a criticalcritical role in the Emergency care of role in the Emergency care of acute stroke patients.acute stroke patients.
Over 400,000 acute stroke patients are being Over 400,000 acute stroke patients are being transported annually by EMS providers.transported annually by EMS providers.
50% of all stroke patients use EMS, but this is the 50% of all stroke patients use EMS, but this is the majority of patients who present within the 3 hour majority of patients who present within the 3 hour treatment windowtreatment window
EMS use decreases time to hospital arrival and the EMS use decreases time to hospital arrival and the ability to implement acute stroke intervention.ability to implement acute stroke intervention.

You are dispatched to a call of a 75-year-old female with sudden onset of trouble walking; she has become dizzy and very nauseated. She cannot walk without holding onto furniture. Her blood pressure is 160/90. Her blood sugar is normal. The cardiac monitor shows sinus rhythm. She has no c/o chest pain. She is a non-drinker/non-smoker, but takes medication for high blood pressure. She has no facial droop or arm weakness. You suspect this could be stroke. What area of the brain could give you these symptoms?
