A comatose person cannot be awakened, fails to respond normally to pain, light or sound, does not have sleep/wake cycles and does not initiate voluntary actions. (More than 6 days). The underlying cause of coma is bilateral damage to the Reticular Activating System in the midbrain which is important in regulating sleep Coma can result from: stroke, trauma, intoxication, hypoxia or induced as a form of preserving higher brain function during healing process
Generally, brain injury is classified as: Severe, with GCS less than 8 Moderate, GCS 9 - 12 Minor, GCS greater than 13. Glasgow Coma Scale What is Sleep? Your bodys own circadian rhythm biological clock You dont have to do anything to allow your normal sleep pattern to emerge..its called a free running
cycle When your parents brought you home from the hospital and trained you to sleep at nightthat is called entrainment When you have sleep deprivation you will make up for it by sleeping more in REM sleep days later. This is called REM Rebound. Many states of consciousness Unconscious physically unable to awaken
Subconscious inner thoughts and feelings you are not totally aware of A comatose person cannot be awakened, fails to respond normally to pain, light or sound
The severity of a coma is measured by the Glasgow Coma Scale. Circadian rhythms are Your natural biological clock Entrainment is
Training your body when to sleep When you dont get enough sleep its called Sleep Deprivation Making up for lost sleep time by sleeping more for a few days is: REM Rebound What exactly happens during sleep? You cycle through various stages when you are sleeping. Types of Sleep: Non REM

Twilight Sleep: sensation of falling, peaceful, hazy, Melatonin triggered Fail to immediately respond to outside stimuli Stage 1: Sudden twitches and hypnic jerks (myoclonus reactions) Lose most conscious awareness of the external environment. Stage 2: sleep spindles (bursts), lose all awareness of environment Stage 3: Slow wave sleep sleep walking, bedwetting can be issues Stage 4: Heart beat drops, BP low, H.G.H secreted REM BEGINS

You begin REM Sleep (Rapid Eye Movement) Every 90 minutes after falling asleep your eyes jerk back and forth in various directions Your limbs become paralyzed B.P., heart rate increases Through the night you cycle through stages with REM increasing in length then decreasing towards awakening. REM SLEEP
REM sleep in adult humans typically occupies 2025% of total sleep about 90120 minutes of a night's sleep. During a normal night of sleep, humans usually experience about four or five periods of REM sleep; they are quite short at the beginning of the night and longer toward the end. Many animals and some people tend to wake, or experience a period of very light sleep, for a short time immediately after a bout of REM. The relative amount of REM sleep varies considerably with
age, lessening with age. A newborn baby spends more than 80% of total sleep time in REM During REM, the activity of the brain is quite similar to that during waking hours; for this reason, the REM-sleep stage may be called paradoxical sleep Vividly recalled dreams mostly occur during REM sleep How does our body know when to sleep? What is Sleep Deprivation
Sleep time seems to decrease from about 16 to 18 hours for a newborn to 7 or 8 for an adult . What have we learned?
What controls your sleep cycles? Reticular Activating System What controls your temperature? Hypothalmus
What is your free running cycle called? Circadian Rhythm How many stages is Non REM sleep? 4, (5 with twilight sleep) What is REM? Rapid Eye Movement Sleep
How often do you fall into REM Sleep? Every 90 minutes after falling asleep What happens during REM Sleep your eyes jerk back and forth in various directions and your limbs become paralyzed B.P., heart rate increases Have you ever walked in your sleep?
