Document Summary
Levels of consciousness (loc)---- name, date, where you are, who they are, is it day time?--- looks at frontal lobe. State of awareness of oneself and the environment. Arousal different levels of arousal- sometimes you just talk, sometimes you shake them lightly, sometimes you shake harder, sometimes you inflict a small amount of pain. Vegetative state---no real aropusal or consciousness of environment. Divided by location above or below the tentorial plate. Metabolic--- liver failure we get toxins because liver is what purifies the body. Psychogenic ----- sometimes but also a lot of phychiatric meds cause problems too. Cheyne-stokes respirations (csr)--- ramping up of breathing than decrease. Oculomotor responses usually only checked later on when things get really bad. Sudden, transient alteration of brain function caused by an abrupt explosive, disorderly discharge of cerebral neurons. Tonic-clonic (jerky, contract-relax) movements associated with some seizures. Epilepsy: no underlying cause can be found (idiopathic)---- we have no idea why they are having seizures.
