The Cincinnati Prehospital Stroke Scale (CPSS) is a validated prehospital stroke screening tool that has been easily and widely adopted by all levels of EMS providers. The CPSS is scored from 0 to 3, with one point given for each of the following physical exam findings: facial droop, arm drift, and slurred speech.
What is a large vessel occlusion stroke?
Large vessel occlusion (LVO) is the obstruction of large, proximal cerebral arteries and accounts for 24–46% of acute ischaemic stroke (AIS), when including both A2 and P2 segments of the anterior and posterior cerebral arteries (1).
What are the 3 types of strokes?
