The MySleepDash Mobile Application software is intended to be used in conjunction with Transcend Continuous Positive Airway Pressure (CPAP) devices to support individuals diagnosed with obstructive sleep apnea (OSA). The application enables users to view therapy data, monitor device usage, and adjust comfort settings. The application is also intended for healthcare professionals to configure Transcend CPAP device settings. It does not provide automated diagnosis or treatment recommendations and should be used in conjunction with professional medical oversight. Transcend CPAP devices are intended for use in adults adults weighing over 66 pounds (30 kg). These devices are intended for home and hospital/institutional use. This mobile health application is for prescription use only (Rx Only).
Device Story
MySleepDash is a mobile health application acting as a software accessory for Transcend CPAP devices. It connects to CPAP hardware via Bluetooth Low Energy (BLE) to synchronize therapy data, including usage hours, mask leak, AHI, and device settings. The app provides a user interface for patients to view sleep metrics and adjust comfort settings (e.g., AirRelief, GentleRise) and for clinicians to configure therapy settings. Data is transmitted to a secure cloud platform for storage and remote monitoring. The device does not provide automated diagnosis or treatment recommendations. It benefits patients by facilitating therapy adherence and engagement through data visualization and remote clinician oversight. It is used in home and clinical environments by patients and healthcare professionals.
Clinical Evidence
No clinical trials were conducted. Evidence consists of usability engineering studies involving both patient and clinician users to validate critical tasks, BLE connectivity, and cloud functionality. Non-clinical testing included software verification and validation (functional and non-functional requirements), risk management (95 use-related and 56 design risks mitigated), and cybersecurity threat assessment (12 scenarios).

Dear William Brown:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

The MySleepDash Mobile Application and the predicate device both function as mobile software accessories to CPAP devices, providing therapy data visualization, compliance tracking, and wireless communication with the device. Both systems limit user interaction to comfort-related settings while maintaining control of therapy-critical parameters within the prescribed device configuration. Additionally, both devices utilize mobile applications with cloud-based data storage. MySleepDash has been developed in accordance with current FDA software and cybersecurity guidance, with comprehensive documentation supporting software verification, validation and risk management. These similarities in functionality, architecture and controls support a determination of substantial equivalence and do not raise new questions of safety or effectiveness.
## Substantial Equivalence Conclusion:
The MySleepDash Mobile Application has the same intended use, similar technological characteristics, and substantially equivalent functional performance compared to the predicate device (K160836). Both applications function as mobile software accessories to CPAP devices, providing therapy data display,

compliance and therapy summaries, wireless communication with compatible devices, and appropriate cybersecurity controls. Any minor differences in implementation do not raise new questions of safety or effectiveness. Therefore, the MySleepDash Mobile Application is substantially equivalent to the Monte Carlo predicate device.
## Non-Clinical and Clinical Tests Summary:
The MySleepDash Mobile Application underwent comprehensive risk management, nonclinical testing, and usability validation in accordance with applicable standards and guidance.
Non-clinical verification and validation testing completed for device software functions demonstrated that the device met all intended performance requirements. Testing included:
- Software verification and validation, including non-functional requirements and end-to-end functional testing.
The following FDA guidance were conformed to:
- Content of Premarket Submissions for Device Software Functions: June 2023
- Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions: September 2023
Risk management activities included evaluation of use-related and cybersecurity risks. A total of 95 use-related risks and 56 design risks across 11 software modules were identified and mitigated through design controls. Residual risks were reduced to acceptable levels, with the highest residual risks associated with user-dependent factors (e.g., login errors, network instability) and controlled through interface design, access restrictions, and user notifications. Cybersecurity risk assessment evaluated 12 threat scenarios; all residual risks were reduced to acceptable levels, including a justified residual risk related to BLE pairing mitigated through physical proximity requirements and encryption. No residual risks are expected to result in serious harm, and the overall benefit-risk profile is considered favorable.
Clinical evaluation was conducted through usability engineering studies to demonstrate that intended users can safely and effectively perform critical tasks. Usability testing included both user and clinician modes, evaluation of BLE connectivity to Transcend CPAP devices, and associated cloud functionality in the intended use environment. Results confirm that the application supports safe and effective use in both home and clinical settings.
## Conclusion:
Based on the results of nonclinical verification and validation testing, usability engineering evaluation, and comprehensive risk management activities, the MySleepDash Mobile Application has been demonstrated to perform as intended and to be safe and effective for its intended use. All identified risks have been mitigated to acceptable levels, and no new risks to safety or effectiveness have been identified. The testing supports that the device is substantially equivalent to the predicate device and does not raise different questions of safety and effectiveness.
