the single most important laboratory technique used in the diagnosis and treatment of sleep disorders, especially those associated with excessive daytime somnolence. Polysomnographic (PSG) study The term PSG was proposed in ______ 1974 stage of sleep in which the most severe apneic episodes are noted REM sleep required to sufficiently record all stages of sleep including REM sleep all-night PSG in REM sleep the maximum __________ desaturation occurs. oxygen during CPAP titration, it is es...

What would increase the resolution of EEG spikes and improve the definition of high frequency activity? Recording with a high sampling rate What stage would the epoch shown below be scored as? Stage N1 The cortical activity seen at the very end of the epoch in question 2, is best described as: Spontaneous arousal Refer to the image in question 2 above, the light grey vertical lines represent: One second markers Which of the following actions should be taken to avoid ground loops: Ensur...

4 Stages 37-48 weeks CA Stage W, Stage N, Stage R, Stage T In infants, score wake if all of the following are met - eyes open intermittently - REM or scanning eye movement - sustained chin EMG tone with bursts of muscle activity - irregular respiration - LVI or M in EEG waves In infants, score N(REM) if - eyes closed with no eye movement - chin EMG tone present - Regular respiration - TA, HVS, Sleep spindles - reduced movement relative to wake In infants, score REM if - low chin EMG...

A child comes into a sleep lab for a study. When asked to change into his pajamas, the child responds that he does not own any. While performing the hookup, you notice that his hair and skin are extremely dirty, he is extremely thin, and his clothes are unwashed. These may be signs of physical neglect A respiratory rate between 24-38 breaths/min is typical for which age range? 0-1 years old As a child develops, their heart rate gradually decreases with age At which age would toilet traini...

How to you calculate the Total Recording Time (TRT)? Epoch number of "Lights on" - Epoch number "Lights out" / 2 How do you calculate Total Sleep Time (TST)? Total epochs of N1 + N2 + N3 + R / 2 How do you calculate Sleep Period Time (SPT)? Last epoch of sleep - first epoch of sleep / 2 How do you calculate percentage of time in each sleep stage (% N1, % N2, % N3, % R)? % N1= minutes of N1 / TST x 100 % N2 = minutes of N2 / TST x 100 % N3 = minutes of N3 / TST x 100 %R = minutes of...

what is the calibration, asking the patient do perform certain exercises, in a routine PSG overnight study Verify patient identification (x2) Eyes closed 30 sec Eyes open 30 sec Look left and Look right x2 Look up and Look down x2 Blink 5 times quickly Stick your jaw way out/clench teeth/Bite down hard Move left foot (Dorsiflex) Move right foot (Dorsiflex) Move left arm (if applicable) Move right arm (if applicable) Fake snore/Fake cough Breathe in Breath out Breathe through the...

What is the frequency of a wave? Characterized by the number of times it repeats or oscillates in a second; measured in Hz or Cycles per second (cps); the narrower the wave, the faster it is, and therefore the higher the frequency What is the amplitude of a wave? It is directly affected by the voltage of the associated signal; it is the height of the wave What is Time Constant? Also called fall time or fall time constant; the amount of time for a calibration wave to fall from its highe...
