What is a polysomnography? CORRECT ANSWER Sleep study What part of the brain are we most interested in? CORRECT ANSWER Thalamus, controls consciousness and sleep What is an electroencephalogram (EEG)? CORRECT ANSWER A measure of electrical activity of the brain recorded across the scalp. What is an electrooculgraphy (EOG)? CORRECT ANSWER Measures electrical activity of the eye and is essential for the documentation of the rapid eye movements characteristic of REM sleep. What is obstr...

Bruxism Scoring CORRECT ANSWER 1. May consist of brief or sustained elevations of chin EMG activity at least twice the amplitude of background EMG. 2) 0.25 - 2 seconds in duration and if at least 3 elevations in a regular sequece. 3) sustained elevations of chin EMG if more than 2 seconds. 4) 3 seconds of stable background before new episode can be scored 5) It can be scored with a min of 2 audible tooth grinding (in absence of epilepsy) EFM (Excessive Fragmentary Myoclonus) CORRECT A...

Daytime nap studies list the types of overnight polysomnograms: CORRECT ANSWER could be level 1 or 2, seizure montages, CPAP titrations, etc list the types of daytime nap studies: CORRECT ANSWER multiple sleep latency test, maintenance of wakefulness test list the required equipment and components of a routine PSG (level 1): CORRECT ANSWER - EEG or electroencephalogram (a minimum of F4/M1, C4/M1...

CPSGT Practice Test 2 (Polysomnography) 100% PASSThe goals of PAP therapy include all of the following EXCEPT to ve diminished lung capacity. b. eliminate flow limitations in the upper airway. c. eliminate excessive daytime somnolence. d. eliminate snoring. - ANSWER-A: Improve diminished lung capacity. The CPAP and BiPAP used in the sleep lab are non-invasive respiratory therapies that do not have effects on patient's lung capacity or tidal volumes. The focus of the PAP devices is to ma...
