Remmers Sleep Recorder (Formerly known as SnoreSat™)
SagaTech manufactures and markets the Remmers Sleep Recorder which records diagnostic indicators of sleep apnea, detects periodic leg movements(1) in adults, and monitors the effectiveness of CPAP therapy. The Remmers Sleep Recorder is convenient and easy to use; the client attaches the necessary probes so that no technician or specialist need be present. A Windows™-based software package is included, providing data analysis on a personal computer and display of processed and unprocessed data. Test results are presented in a convenient, reliable, and inexpensive manner. The Remmers Sleep Recorder has been approved for sale in Canada and the USA.
The Remmers Sleep Recorder (Formerly SnoreSat™) records signals that are commonly used in diagnosing patients who are suspected of having sleep apnea. These signals are:
- Blood oxygen saturation
- Heart rate
- Pulse amplitude
- Nasal airflow (through nasal cannula pressure measurement)
- Respiratory airflow (through pneumotachograph when CPAP is used)
- Mask pressure (when CPAP is used)
- Snoring sound
- Body position
- Respiratory movements
The Remmers Sleep Recorder also records electromyograms which can be used in the diagnosis of other sleep disorders.
- Leg electromyograms for the diagnosis of periodic leg movements
- Masseter electromyograms for the diagnosis of bruxism
 Physical Description
Technical Characteristics
- Memory Capacity
Between 8 and 36 hours depending on how many channels are being recorded (the more channels being recorded, the shorter the time to reach capacity)
- SpO2 Accuracy
Using the Nonin Adult Flex Sensor (8000J-3) 70 -100%. In this range, accuracy is ± 2 percentage points Below 70%, accuracy is not specified
- Pulse Rate Accuracy ±3% ±1 digit over the range of 18 to 300 beats per minute
Nasal prongs record respiratory airflow in diagnostic studies.
An in-line pneumotachograph measures respiratory airflow during treatment studies. Two bioelectric channels are provided for use in recording electromyograms of leg muscles or the masseters.

Notes:
(1) These are periodic and repetitive contractions of the leg during sleep. As with sleep apnea, these abnormal movements may cause a person to awaken up to hundreds of times during the night causing fatigue during the day. Periodic leg movements are more likely to occur in older patients.
