Study Notes
AASM Scoring Manual
- A standard reference for sleep scoring and Sleep Technologists
Professional Sleep Organizations
- BRPT (Board of Registered Polysomnographic Technologists): provides RPSGT examination
- AASM (American Academy of Sleep Medicine): a professional sleep organization
- AAST (American Association of Sleep Technologists): a professional sleep organization
Paper Speed
- Important setting for sleep studies
Types of Sleep Studies
- PSG (Polysomnogram): diagnostic study
- CPAP (Continuous Positive Airway Pressure): treatment study
- MSLT (Multiple Sleep Latency Test): 5 naps, 20 minutes to fall asleep
- MWT (Maintenance of Wakefulness Test): 4 trials
- HSAT (Home Sleep Apnea Test)
10/20 System
- Used to measure and name sites on the scalp
Sleep Hygiene
- Important for sleep quality and disorders
Sleepiness Assessment Tools
- Berlin Questionnaire: assesses sleep apnea risk
- Epworth Sleepiness Scale: measures daytime sleepiness
Bio Cals
- Performed to calibrate equipment
- Exercise: clenching teeth, looking up and down, and rapid eye movements
Frequency of Sleep Waves
- Alpha waves: 8-12 Hz
- Beta waves: 13-30 Hz
- Theta waves: 4-8 Hz
- Delta waves: 0.5-4 Hz
- Spindles: 12-16 Hz
- K complex: high-amplitude wave
Epoch
- Duration: 30 seconds
Stages of Sleep
- Characteristics: N1, N2, N3, REM
REM Latency
- Time from sleep onset to first REM period
Pediatrics Studies
- Capnograph and CO2 monitoring: used to monitor breathing
Proper Documentation
- Important for patient care and study results
Instrumentation
- Filter: removes noise from signals
- Sensitivity: adjusts amplification of signals
- Amplifier: increases signal strength
- Impedance: measures resistance to electrical signals
- Current, voltage, resistance: important electrical concepts
Sterilization
- Important for infection control
Hypnogram
- Visual representation of sleep stages
Transitional Sleep
- Periods of transition between sleep stages
Apnea Duration Requirement
- Criteria for scoring apneas and hypopneas
Bruxism
- Teeth grinding during sleep
REM Sleep Effects
- Affects body systems, such as cardiovascular and nervous systems
Channels in a Sleep Study
- EEG (Electroencephalogram): measures brain waves
- EMG (Electromyogram): measures muscle activity
- ECG (Electrocardiogram): measures heart activity
- etc.
