The summary explicitly states that the device contains the "same algorithm as the predicate Silent Night V device" and mentions no AI/ML terms or concepts.
No
The device is indicated for "diagnostic evaluation of adults with possible sleep apnea" and "stores sleep disordered breathing information and statistics", which are diagnostic functions, not therapeutic ones.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The ACCUSOM device is indicated for use in the diagnostic evaluation of adults with possible sleep apnea." This directly identifies its purpose as diagnostic.
No
The device description explicitly states that the ACCUSOM device is a "battery and line powered ventilatory effort recorder" and includes physical components like sensors, cables, and a device positioned on the patient's arm. It also mentions recharging and data upload via cellular network or RS232 cable, all indicating a hardware component is integral to the device's function.
Based on the provided text, the ACCUSOM device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- ACCUSOM Function: The ACCUSOM device measures physiological signals directly from the patient's body (arterial oxygen saturation, pulse rate, respiration effort, airflow waveform, sound intensity). It does not analyze samples taken from the body.
- Intended Use: The intended use is for the diagnostic evaluation of sleep apnea by monitoring physiological parameters during sleep.
Therefore, the ACCUSOM device falls under the category of a medical device that monitors physiological signals, not an in vitro diagnostic device.

Device Description
The ACCUSOM device is a battery and line powered ventilatory effort recorder. The ACCUSOM device provides physiological measurements that are identical to the predicate Silent Night V device including:
- Arterial oxygen saturation level (SpO2)) (Sampled every 5 (+/- 0.2 . seconds))
- Pulse Rate (Sampled every 5 (+/- 0.2 seconds)) .
- Respiration effort signal (Sampled every 100 (+/- 0.5 mseconds)) .
- Airflow waveform corrected for ambient room noise (Sampled at 5.2083 kHz, . accurate to 100ppm over the operating temperature range)
Throughout a typical sleep study, sleep disordered breathing information and statistics are stored into the ACCUSOM memory. The stored information includes time and duration of apneas and hypopneas, blood oxygen saturation levels, pulse rate, respiratory effort level, sound intensity level, epoch numbers, and paused time intervals. The new ACCUSOM device can retain three 8.5-hour sleep studies. Existing software retrieves, scores, displays and prints the collected data on a personal computer platform. A summary report and event log can be provided to the physician to view the sleep data.
The ACCUSOM is a battery-powered device with cables that attach to a nasal sensor, to a respiratory effort sensor, and to a blood oxygen saturation sensor (SpO2). The ACCUSOM contains visual and audible sensor status indicators for the patient's convenience. At the end of each night of testing, the sensors are removed and the ACCUSOM is plugged into a wall outlet to recharge and to upload the previous night's data using the cellular network to NovaSom, Inc. for report preparation. If the cellular network is insufficient in the patient's residence, the ACCUSOM data will be downloaded using the traditional RS232 cable connection upon receipt at NovaSom, Inc.

NovaSom, Inc. (formerly Sleep Solutions, Inc.) owns the 510(k) for the predicate Silent Night V (K000253). The Silent Night V device was cleared in 2000 and has been in use since that time with no adverse or reportable events and no issues related to reliability. The ACCUSOM device is the next generation to the Silent Night V (K000253).
NovaSom, Inc. was formerly known as Sleep Solutions, Inc. The name change to NovaSom, Inc. took place on September 10, 2010. NovaSom, Inc. was last inspected by the FDA in December, 2009 while still under its previous name of Sleep Solutions. Inc.
The ACCUSOM device provides physiological measurements that are identical to the predicate Silent Night V device including:
- Arterial oxygen saturation level (SpO2)) (Sampled every 5 (+/- 0.2 . seconds))
- Pulse Rate (Sampled every 5 (+/- 0.2 seconds)) .
- Respiration effort signal (Sampled every 100 (+/- 0.5 mseconds)) .
- Airflow waveform corrected for ambient room noise (Sampled at 5.2083 kHz, . accurate to 100ppm over the operating temperature range)
As consistent with the predicate Silent Night V device, throughout a typical sleep study, sleep disordered breathing information and statistics are stored into the ACCUSOM memory. The stored information includes time and duration of apneas and hypopneas, blood oxygen saturation levels, pulse rate, respiratory effort level, sound intensity level, epoch numbers, and paused time intervals. The new ACCUSOM device can retain three 8.5-hour sleep studies. Existing software retrieves, scores, displays and prints the collected data on a personal computer platform. A summary report and event log can be provided to the physician to view the sleep data.
The ACCUSOM is a battery-powered device with cables that attach to a nasal sensor, to a respiratory effort sensor, and to a blood oxygen saturation sensor (SpO2). The ACCUSOM contains visual and audible sensor status indicators for the patient's convenience. At the end of each night of testing, the sensors are removed and the ACCUSOM is plugged into a wall outlet to recharge and to upload the previous night's data using the cellular network to NovaSom, Inc. for report preparation. If the cellular network is insufficient in the patient's residence, the ACCUSOM data will be downloaded using the traditional RS232 cable connection upon receipt at NovaSom, Inc.
