Distinguish Between Cerebral Death & Brain Death? (P.362)
|
Cerebral Death:
- Irreversible Coma - Death of Brain Stem & Cerebellum - Brain Can Maintain Homeostasis Brain Death: - Brain is Damaged So Completely It Cannot Recover - Brain Cannot Maintain Homeostasis - Irreversible Cessation of Entire Brain |
|
Define Seizure? (P.363)
|
- Sudden Explosive Disorderly Discharge of Cerebral Neurons
- Involves Motor, Sensory, Autonomic, or Psychic Manifestations - Produces Brief Disruption of Brains Electrical Functions |

|
Characterize the Stages of ICP? (P.372)
|
Stage 1:
- Compensates by Vasoconstriction & External Compression of Venous System - ICP May Not Change Due to Compensation Mechanism - PERRLA Stage 2: - Subtle Clinical Manifestations Confusion, Restlessness, Drowsiness - PERRLA - Immediate Surgical/Medical Intervention Required Stage 3: - Autoregulation (Compensatory Regulation of Cranial Blood Vessels) Is Lost - Brain Tissue Experiences Severe Hypoxia/Acidosis Stage 4: - Brain Tissue Herniates (Shifts) - Systolic Arterial Pressure Equal ICP and Blow Flow Stops |
