Consciousness - Answer-awareness of oneself and one's environment • late 19th century: major subject of study in psychology • early 20th century: behaviourism considered it a mere product of behaviour. • mid-late 20th century: interest in mental processes increases • currently: how does it arise from the functioning of the brain? Gerhard Roth - Answer-• He defined 2 forms of consciousness: Background Stream & Actual Stream. • He also stated that consciousness comprises many st...

Right ventricular infarction (RVI) lead changes - II, III, AVF R ventricular infarction s/s - clear breath sounds, hypotension, JVD. R ventricular dilation and dec contractility>> dec preload and CO Reperfusion therapy standard - Within 60 min of ED arrival Common causes of PEA - Hypoxia, tension pneumo, cardiac tamponade BNP as a marker - of L ventricular dysfunction bc ventricles make BNP and an inc of over 100 pg/ml indicates symptomatic HF Transcutaneous pacing (TCP) - ...

Rolandic Spikes - what type of spikes are seen most often in children 5-6 Hz - by year one what should the dominant background rhythm be 5 Hz - what should the PDR of a awake 5 month old infant be ORIDA - what encephalopathic EEG pattern is most commonly associated with children Benign Rolandic Epilepsy - onset of between 3 and 13 years begins with sensorimotor manifestations on one side of the face and mouth Unilateral oral paresthesias as well as facial clonic and/or tonic activity are c...

Stages of sleep : 1, 2, 3, 4 (all NREM) and REM Stage 1 sleep : light sleep, muscle activity slows down, occasional muscle twitching NREM Stage 2 sleep : Breathing pattern and heart rate slows, decrease in body temperature NREM Stage 3 sleep : Deep sleep begins, slow delta waves generated NREM Stage 4 sleep 2 | P a g e : very deep sleep, rhythmic breathing, limited muscle activity, brain produces delta waves REM sleep : Brainwaves speed up, dreaming occurs, muscles relax, heart rat...
