Design verification tests were performed on Somnolyzer 24x7 as a result of the product requirements. Respironics has determined that the modifications have no impact on the safety and effectiveness of the device. In summary, the device described in this substantially equivalent to the predicate device. . . {1}------------------------------------------------ The modified device complies with the applicable standards referenced in the Guidance for FDA Reviewers and Industry "Guidance for the Content of Pre-market Submissions for Software Contained in Medical Devices," May 2005. # Indications for Use Somnolyzer 24x7 is a computer program (software) intended for use as an aid for the diagnosis of sleep and respiratory disorders. Somnolyzer 24x7 is intended to be used for analysis (automatic scoring and manual re-scoring), display, redisplay (retrieve), summarize, reports generation and networking of data received from monitoring devices typically used to evaluate sleep and respiratory related sleep disorders. This device is to be used under the supervision of a physician. The indications for use remain unchanged from K083620. # Device Description Somnolyzer is a polysomnography scoring application that provides automated analysis of sleep, respiratory and movement information recorded during sleep studies. It processes information recorded during sleep by electrodes and sensors attached to the body. It then generates results that include quantitative sieep, breathing and motion parameters, used to evaluate sleep and respiratoryrelated disorders. Somnolyzer 24x7 scoring is applicable to adult patient populations only. Somnolyzer 24x7 version 2.5 provides an update to the currently released Somnolyzer 24x7 (K083620), which enables Somnolyzer to score sleep recordings according to the American Academy of Sleep Medicine (AASM) Manual 2007 and 2012 editions. # Description of Modifications. The fundamental scientific technology of Somnolyzer 24x7 is unchanged from the predicate device (K083620). Respironics has made the following changes to the previously cleared Somnolyzer 24x7 to be considered for this submission: - Modifications to accommodate the AASM rules up to the 2012 edition: . To accommodate the American Academy of Sleep Medicine (AASM) scoring rules, various algorithms in the Somnolyzer 24x7 software were updated to add inputs. The use of additional EEG leads in the AASM recommended EEG montage were built into the software for detecting {2}------------------------------------------------ sleep staging and arousals. A CPAP flow sensor and pressure transducer air flow channel were added as valid inputs into the software. In sleep studies where the primary air flow channels are absent or have produced unreliable data, the respiratory effort belt signal can now be used to derive an air flow signal, known as RIPflow was added as an optional flow channel in the AASM 2012 manual. Sleep staging and respiratory event scoring rules were also updated to incorporate new rules with the AASM 2012 edition. Somnolyzer has the ability to support the sub-classification of hypopneas, as well as detect Cheyne Stokes breathing patterns. #### . Other improvements: In addition to the AASM updates, Somnolyzer 24x7 was modified to provide clinician configurability of several scoring parameters, accept ECG input for signal processing (allow for removal of ECG electrical interference in the EEGIEOG/EMG data, use the ECG signal in respiratory event detection as part of the scoring consideration for hypopneas), and identify and select the EMG channel with the most viable data for scoring. # Non-Clinical Tests Verification activities were performed to verify that the software modifications performed as intended and did not affect safety and effectiveness. Two types of testing were conducted: verification tests and automated validation tests. The verification testing involved verifying the results from the autoscoring algorithms. The automated validation testing compared the performance of human manual scoring against Somnolyzer 24x7 version 2.5 and previous versions of Somnolyzer. Testing included software code reviews, bench verification testing and user manual inspection. The verification and validation testing demonstrates that all new requirements have been satisfied and safety and effectiveness has not been inadvertently affected by modifications to the system. Testing confirmed that the Somnolyzer 24x7 software version 2.5 performs equivalently to the device predicate Somnolyzer 24x7 software (K083620). All tests had passing results or minor resolved defects. # Clinical Tests Clinical tests were not required to demonstrate the safety and effectiveness of Somnolyzer 24x7. Product functionality has been adequately assessed by non-clinical tests. {3}------------------------------------------------ t. # Conclusion Somnolyzer 24x7 software has passed all of the aforementioned non-clinical tests and required no clinical tests in order to demonstrate safety or effectiveness. It is therefore concluded that Somnolyzer 24x7 is substantially equivalent to the predicate device. {End of tab} {4}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES October 17, 2013 Public Health Service Food and Drug Administration 10903 New Hampshire Avenue Document Control Center - WO66-G609 Silver Spring, MD 20993-0002 Respironics, Inc.
