Treatment of Obstructive Sleep Apnea (5)Daytime Measurements
All daytime measurements were done the day following nocturnal testing.
Daytime measurements included a brief history, physical examination, and hourly administration of the Stanford Sleepiness Scale, an ordinal scale with seven categories of sleepiness, with one being the most awake and seven being the most sleepy. Administration of the MSLT occurred as follows: subjects were placed in a darkened room and allowed the opportunity to nap for 20 to 21 minutes at 9:30 am, 11:30 am, 1:30 pm, and 3:30 pm. Sleep latency was defined as time from lights-out to onset of the first epoch of stage 2 sleep as defined by the appearance of sleep spindles.

If a sleep spindle was seen at time 20 minutes, the subject was allowed to sleep for 1 to 2 more epochs (30 to 60 seconds). A score of 20 then was given to that nap session. If the subject remained awake during the nap, a score of 21 was given in order to easily identify naps without sleep from those with sleep onset at time 20 minutes. Naps without sleep were recorded as 21 minute sleep latency. The mean sleep latency of the four naps is reported as a summary measurement. Blood pressure measurements were taken every two hours; values reported are means of five measures. Subjects also completed a number of neuropsychologic measures, including the following (as primarily described in Lezak):
Mini-Mental State.” This mental status exam is a quick screen of orientation, short-delay recall, attention, language, and visuospatial processing. buy ortho tri-cyclen online
Finger Tapping Tkst.* One of the tests of the Halstead-Reitan Neuropsychological Test Battery, this is a test of simple motor speed. Data are reported as the average number in a ten-second period.
The Buff 2 6- 7 Tkst. Primarily a measurement of sustained visual attention and concentration. Scores from this test reflect the total number of targets cancelled in five minutes.
