    • prevent sudden arousal from sleep
  71. A person who has ICP....their CO2 should be kept under
  72. The reason why rehab therapy is effective is cuz of Bobath principles.  What are they?
    • you can relearn things even after the brain is damaged cuz:
    • level of excitability of nerve cells is changeable
    • when neural conncections are impaired, there is a degeneration of inhibition that allow previously unused connections to be utilized
    • collateral sprouting
  73. What does it mean when you say the excitability of nerve cells is changeable?
    if a cell dies, remaining cells can produce a better response to the lower input received from fewer cells
  74. What is collateral sprouting?
    when previously unconnected axons attached to dendrites of cells deprived of input cuz of cell deaths, provide new input
  75. What does medicare type D cover?
    medications up to $2800, then the pt pays 100% of drug charges
