Devices are default configured in Therapy-ON mode and provide the most recent six nights of detailed information in the “Daily Reports” format. The Daily Report in Therapy-ON mode allows users to determine:
  • The number of times you attempt to sleep on your back and how quickly you respond to therapy, shown by the number and thickness of red lines in the Sleep Position graph.
  • Your sleep efficiency, how long you were awake after initially falling asleep, and the number of times you awakened during the night. The intensity of the neck movement (used to determine an awakening) is presented with a combination of height and darkness of the line in the Behavioral Sleep/Wake graph.
  • The percentage of the night when loud snoring was detected, while you were asleep. The intensity of the snoring is presented using a combination of height and darkness of the line in the Snoring Level graph.

1a) The first 10-minutes always awake, even if you do fall asleep immediately 5a) Sleep time divided by Recording Time equals Sleep Efficiency (%Eff). WASO is the sum of total time awake after initially falling asleep
2a) Total number of supine attempts during sleep 6a) Loud snoring is unhealthy when greater than 10.0%
3a) Intensity of awakening 7a) One line represents snoring for each 30-second period
4a) Feedback is delivered every two seconds so the slowest (maximum) positional response to feedback was 80-seconds 8a) Red lines identify supine attempts, i.e., times attempted back sleeping
The Night Shift Portal allows user to set Night Shift to Therapy-OFF mode to monitor sleep patterns. When Trial Mode is selected, the first night is set to Therapy-Off (example below) to obtain a baseline measure of sleep quality. It automatically switches to permanently provide Therapy-On (example above), while saving the first night baseline for comparison. Therapy-Off mode allows users to determine:
  • Your natural tendency toward wanting to sleep on your back, and whether this behavioral tendency changes from night to night.
  • The effectiveness of treatment provided by other sleep apnea or snoring therapies when sleeping in all positions

1b ) Taller, darker lines indicate greater intensity of movement during an awakening 5b) The user had 15 supine attempts for a total of 18% of the time asleep
2b ) Number of supine attempts increased without feedback 6b) The difference between supine and non-supine % time snoring suggests an ideal candidate for Night Shift therapy
3b ) The therapy-OFF (feedback-OFF) night is identified for this night’s information 7b) Tall, dark lines indicate very loud, steady snoring
4b) Less than 6 awakenings per hour is considered normal 8b) It is common for snoring intensity to be greater during first half of the night

Study Statistics

Name Abbreviation Description
Recording Time Record Number of hours that night the device was ON

Percent Supine Time Supine % time Percentage of sleep time you were ON your back (supine)
Snoring > 50 dB % > 50 dB Percentage of sleep time snoring was like loud talking
Supine Snoring > 50 dB Percentage of supine sleep time snoring was like loud talking
Non-supine Snoring > 50 dB Percentage of non-supine sleep time snoring was like loud talking



This report is designed to demonstrate to your physician that you are routinely using the therapy, as well as help you monitor your own therapy.


Are you Using the Therapy Enough?
The report shows the number of nights Night Shift was worn long enough to have a marginal-to-good benefit.


Is the Therapy Effective?
The average number of supine (back) sleeping attempts per night and your average non-supine time is provided.



Did your Sleep Quality Improve?
Night Shift computes the monthly average for sleep efficiency and the number of nights your sleep efficiency is in the good range.



Was your Sleep Fragmented?
Awakenings count the number of occurrences that a transition from sleep to wake occurred per hour bed time.



Did your Upper Airway Health Improve?
Night Shift Tracks the average percent of time you snored loudly, % of nights your loud snoring was unhealthy, and whether your snoring is increasing over time (e.g., by trimester).
