Health Management for Older Adults III - Emergency Response to Stroke -- Treatment Issues

< i > Emergency Response to Stroke -- Treatment Issues

The first treatment issue reflects the importance of maximizing perfusion to areas of the brain rendered ischemic by the vascular occlusion due to thrombus or embolus.

The brain regulates its own blood flow by adjusting the degree of constriction of arterioles.

In the face of ischemia, arterioles are maximally dilated. Under these circumstances, blood flow is proportional to blood pressure.
