Yes
The description mentions "auto-scoring algorithms" and specifically names "Somnolyzer" and "Cardio-Respiratory Sleep Staging (CReSS)" as algorithms that perform analysis and infer sleep stage from physiological signals, which are strong indicators of ML/AI techniques being used for automated analysis and interpretation. The performance studies also validate these algorithms against manual scoring, a common practice when evaluating ML/AI models.
No
The device is a software application intended for analysis, display, retrieval, and reporting of data from monitoring devices to aid in the diagnosis of sleep-related disorders, not for direct therapeutic intervention.
Yes
The "Intended Use" section states that Sleepware G3 is used for analysis and processing of data from monitoring devices to "help aid in the diagnosis of sleep-related disorders." The "Device Description" also mentions it's a "polysomnography scoring application" used for "managing data from sleep diagnostic devices."
Yes
The device is described as a "software application" and a "polysomnography scoring application" that runs on a "personal computer" and processes data from "monitoring devices." While it interacts with hardware (monitoring devices and a personal computer), the device itself is the software that performs the analysis, display, and reporting functions. The description focuses solely on the software's capabilities and does not mention any hardware components included with the device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The description of Sleepware G3 clearly states it analyzes data received from monitoring devices used to categorize sleep-related events. These monitoring devices are external to the body and measure physiological signals (like heart rate, airflow, respiratory effort) rather than analyzing biological samples like blood, urine, or tissue.
- The intended use is for analyzing physiological data. The software processes and scores data from sleep diagnostic devices, displays waveforms, and generates reports based on these physiological measurements. This is distinct from the analysis of biological samples that characterizes IVDs.
Therefore, Sleepware G3 is a software application for analyzing physiological data from external monitoring devices, not an IVD.
No
The letter does not explicitly state that the FDA has reviewed and approved or cleared a Predetermined Change Control Plan (PCCP) for this specific device.
Intended Use / Indications for Use
Sleepware G3 is a software application used for analysis (automatic and manual scoring), display, retrieval, summarization, report generation, and networking of data received from monitoring devices used to categorize sleep related events that help aid in the diagnosis of sleep-related disorders. It is indicated for use with adults (18 and older) and infant patients (one year old or less) in a clinical environment by or on the order of a physician.
The optional Somnolyzer scoring algorithms are for use with adults (18 and older) to generate an output that is ready for review and interpretation by a physician. Cardio-Respiratory Sleep Staging (CReSS) is an additionality of Somnolyzer which uses standard Home Sleep Apnea Test HSAT signals (in the absence of EEG signals) to infer sleep stage.

Description of the test set, sample size, data source, and annotation protocol
Five clinical studies were provided in this submission. These clinical studies included a total of 1.204 polysomnography (PSG) and home sleep apnea test (HSAT) files to validate the Somnolyzer and CReSS algorithms against manual scoring. Four studies assessed the Somnolyzer algorithm. In these studies, The non-inferiority margin for comparisons of Somnolyzer against human scoring were set at the lower-margin of the agreement observed across expert technologists. All of the primary and secondary endpoints were met across all studies, and thus it was concluded that Somnolyzer is non-inferior to human sleep staging and scoring of the apnea hypopnea index (AHI), arousal index (Arl), periodic limb movement of sleep index (PLMS)), and respiratory event index (REI). By demonstrating non-inferiority against human scoring in a large, diverse sample of PSGs and HSATs collected via a number of different platforms, the data demonstrate that Somnolyzer produces output that is as reliable as the output of sleep technologist scoring and is therefore ready for review and interpretation by a physician. A fifth study assessed the CardioRespiratory Sleep Staging (CReSS) algorithm. In that study, we provide evidence that the REI calculated using total sleep time determined by the CReSS algorithm applied to heart rate and airflow signals is a more accurate estimate of the AHI than the REI calculated using total recording time. Accuracy is further improved when CReSS is applied to the heart rate, airflow, and respiratory effort signals (the mean difference between the REI and AHI was reduced from -6.6 events/hour (95% confidence interval -7.51 to -5.71) to -1.76 events/hour (95% confidence interval -2.27 to -1.24) when CReSS was applied to three signals).
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered to have a "moderate" level of concern, since a failure or latent flaw in the software could result in minor harm to the patient.
Non-Clinical Performance Testing: Software verification and validation included software code reviews, automated testing, bench verification testing and labeling review. Testing confirmed that the device under review performs equivalently to the device predicate Sleepware G3 (K142988). All tests had passing results.

Device Description IV.
Sleepware G3 software is a polysomnography scoring application, used by trained clinical professionals, for managing data from sleep diagnostic devices using a personal computer. Sleepware G3 is able to configure sleep diagnostic device parameters, transfer data stored in sleep diagnostic device memory to the personal host computer, process and auto-score data to display graphical and statistical analyses, provide aid to clinical professionals for evaluating the physiological data waveforms relevant to sleep monitoring, and create unique patient reports.
Sleepware G3 includes an optional Somnolyzer plug-in. The auto-scoring algorithms of the Somnolyzer Inside software can be used in addition to, or in the place of, the auto-scoring algorithms that are included in Sleepware G3.
Sleepware G3, remains unchanged in function and fundamental scientific technology from Sleepware G3 which was cleared under K142988.
Intended Use V.
Sleepware G3 is a software application used for analysis (automatic and manual scoring), display, retrieval, summarization, report generation, and networking of data received from monitoring devices used to categorize sleep related events that help aid in the diagnosis of sleep-related disorders.
The optional Somnolyzer software application is intended to mark sleep study signals in order to aid in the identification of events and annotation of traces; automatically calculate measures obtained from recorded signals (e.g. magnitude, time, frequency and statistical measures of marked events); and infer sleep staging in the absence of EEG. All output subject to verification by a qualified user.
Comparison of Technological Characteristics with the Predicate Device
The predicate Sleepware G3 software (cleared in K142988), and the subject device software Sleepware G3 K202142 are designed to detect events for polysomnography with electroencephalography. While the Indications for Use statement for Sleepware G3 is not identical to the predicate device, the differences do not alter the intended diagnostic use of the device relative to the predicate. The Indications for Use have been updated to now include that Somnolyzer's scoring results are ready to review by a physician, which is one of the modifications being proposed in this subject and predicate device is based on the following technological elements:
5
- . Same intended use as the Sleepware G3 (K142988).
- . Same control mechanism and real-time operating principle as Sleepware G3 (K142988).
- . Same technology and user interface as Sleepware G3 (K142988).
The following differences exist between the subject and predicate devices:
Modification #1: Added additional claim to Sleepware G3. .
Somnolyzer's auto-scoring events are non-inferior to manual expert scoring and do not require review by a lab technician.
- For a full PSG acquisition, Somnolyzer scoring for sleep stages according to AASM criteria is o non-inferior to manual expert scoring from a Registered Polysomnographic Technologist (RPSGT).
- For a full PSG acquisition, Somnolyzer scoring for arousals during sleep according to AASM o criteria is non-inferior to manual expert scoring from an RPSGT.
- For a full PSG acquisition, Somnolyzer scoring for apneas and hypopneas during sleep о according to AASM criteria is non-inferior to manual expert scoring from an RPSGT.
- For a full PSG acquisition, Somnolyzer scoring for periodic limb movements during sleep о according to AASM criteria is non-inferior to manual expert scoring from an RPSGT.
- For an HST acquisition, Somnolyzer scoring for apneas and hypopneas according to AASM o criteria is non-inferior to manual expert scoring from an RPSGT.
. Modification #2: Cardio-Respiratory Sleep Staging (CReSS)
For an HST acquisition, Somnolyzer scoring provides an approximate sleep staging based on cardiorespiratory signals (CReSS) such that (given Somnolyzer apnea and hypopnea scoring) the AHI based on the cardio-respiratory feature-based sleep time is superior to the REI based on monitoring time.
Somnolyzer's Cardio-Respiratory Sleep Staging (CReSS) applies clinically-validated algorithms to provide sleep staging for HST studies.
. Modification #3: Indications for Use update
The Indications for Use statement now includes language that Somnolyzer's scoring results are ready to review by a physician. There are no other changes to the Indications for Use from what was previous cleared in K142988. While the Indications for Use statement for Sleepware G3 is not identical to the
6
predicate device, the differences do not alter the intended diagnostic use of the device to the predicate. Please refer to the table below for a side by side comparison of the predicate and subject device Indications for Use statements.

Performance Data Provided to Demonstrate Substantial VI. Equivalence:
Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered to have a "moderate" level of concern, since a failure or latent flaw in the software could result in minor harm to the patient.
Non-Clinical Performance Testing
Software verification and validation included software code reviews, automated testing, bench verification testing and labeling review.
Testing confirmed that the device under review performs equivalently to the device predicate Sleepware G3 (K142988). All tests had passing results.
Clinical Performance Testing
Five clinical studies were provided in this submission. These clinical studies included a total of 1.204 polysomnography (PSG) and home sleep apnea test (HSAT) files to validate the Somnolyzer and CReSS algorithms against manual scoring. Four studies assessed the Somnolyzer algorithm. In these studies, The non-inferiority margin for comparisons of Somnolyzer against human scoring were set at the lower-margin of the agreement observed across expert technologists. All of the primary and secondary endpoints were met across all studies, and thus it was concluded that Somnolyzer is non-inferior to human sleep staging and scoring of the apnea hypopnea index (AHI), arousal index (Arl), periodic limb movement of sleep index (PLMS)), and respiratory event index (REI). By demonstrating non-inferiority against human scoring in a large, diverse sample of PSGs and HSATs collected via a number of different platforms, the data demonstrate that Somnolyzer produces output that is as reliable as the output of sleep technologist scoring and is therefore ready for review and interpretation by a physician. A fifth study assessed the CardioRespiratory Sleep Staging (CReSS) algorithm. In that study, we provide evidence that the REI calculated using total sleep time determined by the CReSS algorithm applied to heart rate and airflow signals is a more accurate estimate of the AHI than the REI calculated using total recording time. Accuracy is further improved when CReSS is applied to the heart rate, airflow, and respiratory effort signals (the mean difference between the REI and AHI was reduced from -6.6 events/hour (95% confidence interval -7.51 to -5.71) to -1.76 events/hour (95% confidence interval -2.27 to -1.24) when CReSS was applied to three signals).
VII. Conclusion
The modified Sleepware G3 includes new technological characteristics that do not raise different questions of safety and effectiveness. The proposed scientific evidence and performance testing to
8
evaluate these new and different characteristics are acceptable and demonstrate substantial equivalence to the legally marketed predicate K142988 Sleepware G3.
