Sleep architecture shows multiple periods of stage two, several periods of stage two/three, one period of stage four and two REM periods (supine and non-supine REM sampled during both periods). Several short wake periods and one extended wake period were present. i y is the description of the patient sleep architecture, the amount of NREM sleep (stages 1, 2, 3, 4), REM/dreaming sleep and the number of awakenings present during the study. e of which approximately 45% will be stage 2 sleep and 20% will be stages 3 and 4 sleep (also known as slow wave sleep). REM a e. Also comments are made as to the body position the patient slept – supine or non-supine. n y (time after lights out to the onset of sleep) < 20 n y (amount of sleep time divided by the amount of time available for sleep as a percentage) >80 n ex (number of awakenings or changes in brain wave frequency per hour) <10 In-phase and anti-phase hypopnoeas were present during supine and non-supine REM and NREM. Isolated central apneas were seen during supine sleep. These events were associated with some arousals and oxygen desaturation. n s has the description of the patients breathing during sleep. Sleep Services Australia uses the AASM (Chicago criteria) for the classification of sleep disordered breathing. o a is the complete absence of breathing for more than 10 seconds. Apnoeas are categorized as follows: Central – where no effort is made to breathe, Obstructive – where no breathing occurs despite repeated efforts to suck air into the lungs against a blocked upper Mixed – where there is a combination of effort to breathe and no effort to breathe. n ea is the partially or incomplete absence of breathing for 10 seconds, like apnoeas these maybe central or Comments are made if oxygen desaturation, snoring or arousals are present with the respiratory events. e are given when awake, in NREM and REM sleep. In normal subjects a slight drop in values from wakefulness to sleep are seen in the order 1-2%. a ir – This is the average oxygen saturation value the patient drops to. i – This is the lowest oxygen saturation value the patient drops to. n ex is the number times per hour the patient has respiratory events regardless of the sleep stage. This is broken down into the 2 main sleep stage categories NREM and REM sleep, some patients will show a worsening of sleep disordered breathing when in REM sleep.

It is a common condition which affects about 10% of the population. It is defined by 4 or more movements of 0.5-5 seconds duration within a 5-90second period. A normal n : Snoring was present throughout the study. E G: The dominant rhythm is Sinus with an average heart rate of 76 bpm. No arrhythmias were present. T. Smith (S n is the Respiratory and Sleep Physicians summary of the condition which has been diagnosed from the sleep study. It contains the comments of the severity of sleep disordered breathing and other conditions such as Periodic Leg movements n are the advised directives from the Respiratory Sleep Physician to the Referring Practitioner to follow with their patient. The list of clinical recommendations is in ranking order of treatment options that should be EEG was recorded from Fp1 – Right outercanthus placement. Wake and NREM was staged according to Rechtschaffen and Kales. REM sleep: EMG unavailable, presence of REM sleep derived from EEG/EOG combined channel (low mixed frequency EEG in the presence of REM’s) Respiratory effort was recorded from uncalibrated thoracic, abdominal respiratory inductive plethysomnography, nasal pressure and snore signal extracted from nasal pressure. Hypopnoeas, Obstructive and Central Apnoeas and Respiratory Effort Related Arousals have been scored in accordance with Chicago Criteria, AASM Task Force Report.
