 Describe the structural anatomy of the normal brain and the alterations in function resulting from stroke.

 Outline the pathophysiology and etiology of stroke.

Describe the components of prehospital care and evaluation of stroke

Stroke

1 / 19

Because of the broader window of treatment time and therapies available, EMS needs to reconsider:

2 / 19

In one study in a suburban/urban, it indicated that EMS system planners may anticipate that approximately 1 in 10 patients (including 1 in 4 with acute ICH) will deteriorate between the scene and the ED arrival.

3 / 19

Many interventions for treatment of acute stroke are most effective when initiated as soon as possible after stroke onset.

4 / 19

Signs can alert the doctors to where the stroke occurred. Signs of stroke are important for EMS to document because it can provide a pre-notification report to the receiving hospital.

5 / 19

Right hemispheric incidents typically show on the left side of the body.

6 / 19

TIAs must be considered a medical emergency because approximately 15% of strokes occur after a TIA.

7 / 19

Physiological and neurological differences present depending on where a stroke occurs.

8 / 19

The Circle of Willis is a joining of arteries:

9 / 19

RACE stroke assessment includes Facial Palsy, arm strength, leg strength, gaze or head deviation, and:

10 / 19

What percentage of stroke patients call EMS over one hour after symptoms began?

11 / 19

In trials, the increase in successful recovery was attributed to faster treatment times.

12 / 19

Stroke can affect: memory, senses, emotions, physical body.

13 / 19

How a stroke affects a person’s physiology depends on where the stroke occurred in the brain.

14 / 19

The majority of strokes are Ischemic.

15 / 19

Hemorrhagic stroke:

16 / 19

Ischemic stroke:

17 / 19

The types of stroke are:

18 / 19

There are ten causes of stroke.
