Intended Use

The Nox T3 device is intended for ambulatory recording of physiological signals during sleep. The recorded signals are then downloaded to a PC where the signals can be viewed and analyzed by use of the Nox T3 application (Noxturnal). The Nox T3 system is indicated for use in patients greater than 2 years of age. The Nox T3 system is NOT intended for any patient monitoring or automatic diagnosis. The intended environments are hospitals, institutions, sleep clinics, or other test environments, including patient's home.

Device Story

Nox T3 is an ambulatory sleep recorder; records physiological signals during sleep for later analysis. Inputs: respiratory effort (abdominal/thoracic), oximetry (via wireless Bluetooth), nasal/mask pressure, snoring, body position/activity (3D accelerometer), audio (microphone), and two auxiliary channels (ECG, EMG, EEG, or EOG). Device is pocket-sized, battery-powered, worn on chest via respiratory effort belt. Data stored on device; downloaded via USB to PC running Noxturnal application. Used in hospitals, clinics, or home; operated by clinicians or patients (hook-up). Noxturnal software provides visualization, manual analysis, and automatic scoring of AHI/ODI. Output assists physicians in diagnosing sleep disorders. Benefits: enables ambulatory sleep studies, reducing need for in-lab polysomnography.

Clinical Evidence

No clinical trials; performance validated via bench testing and comparative analysis. Comparison of Nox T3 signals to Embla N7000 confirmed reliability. Validation of Noxturnal automatic scoring (AHI and ODI) performed using 1,057 historical Embla N7000 recordings previously scored by RPSGT-certified technicians and reviewed by physicians. Results demonstrated automatic scoring is substantially equivalent to manual scoring of full PSG data.

Technological Characteristics

ABS plastic housing; 79x63x21mm; 65g. Sensors: RIP respiratory effort, solid-state pressure, 3D accelerometer, microphone. Connectivity: USB 2.0 (PC), Bluetooth 2.0 (oximeter). Power: 1 AA battery. Software: Noxturnal application for PC (Windows 2000/XP). Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-25/26/40, FCC Part 15.

Indications for Use

Indicated for patients > 2 years of age suspected of Sleep Disordered Breathing (SDB) or Periodic Limb Movement Disorder (PLMD). Not for patient monitoring or automatic diagnosis.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.

The design was verified and validated throughout the design process according to requirement specifications and intended use. Risk analysis was performed according to ISO 14971:2007, appropriate measures were implemented and their effectiveness verified and validated. External test house was used to conduct testing needed to comply with applicable standards reqarding EMC and patient safety as well as additional RF testing to assure compliance to FCC requirements for R&TTE (The Radio and Telecommunications Terminal Equipment Directive) approval. The general process from configuration of device to reading out the results and generating report was validated by having untrained person perform this actions. The results demonstrates that the Nox T3 system has meet its objective of being easy to operate, the Noxturnal interface guides the user appropriately, minimizing the likelihood of errors and lapses, and the design of the Nox T3 components and user instruction allows the hook-up to be performed by untrained people. #### Performance Data The signals recorded with the Nox T3 system were compared to signals recorded with the predicate device Embla N7000. The result demonstrates the reliability and usability of all signals recorded with the Nox T3 system. Analysis comparison was performed to validate the quality of the automatic scoring performed by the Noxturnal application compared to manual scoring of full PSG data. The validation study focused on the comparison of the Apnea Hypopnea Index (AHI) values and the Oxygen Desaturation Index (ODI) values. The recordings used consisted of 1057 Embla N7000 recordings which had all gone through the process of being manually scored by Sleep Technicians with RPSGT certification, and then reviewed by a Physician. The analysis comparison result demonstrates that the Noxturnal application scores AHI and ODI events in a substantially equivalent manner to the manual scoring on full PSG recordings obtained using Embla N7000 recorders. #### Conclusion Verification testing, validation, risk analysis, technological characteristic and performance data comparisons have been performed for the Nox T3 system. The results of this testing and comparisons do not raise new questions of safety and effectiveness and demonstrate the same effectiveness and safety as that of the predicates Compass M10, Embla N7000 and Model 4100 Patient Oximeter Module. The Nox T3 system is therefore substantial equivalent to the predicates Compass M10 from Medcare Flaga (K041724) and Embla N7000 from Medcare Flaga (K024322). The wireless function of the Nox T3 system is therefore substantial equivalent to that of the predicate Model 4100 Patient Oximeter Module from Nonin Medical (K043359). {8}------------------------------------------------ Image /page/8/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
