The summary describes data recording and analysis using an "Autoscoring algorithm for ODI" and comparison to a predicate device's output. There is no mention of AI, ML, or related concepts like neural networks, deep learning, or training/inference processes typically associated with AI/ML. The analysis appears to be based on predefined algorithms rather than learned patterns.
No.
The device is indicated for diagnosis and assessment of sleep disordered breathing, and it records data to produce a report to aid in diagnosis. It does not provide any therapy or treatment.
Yes
The device's intended use explicitly states it "may aid in the diagnosis and assessment of sleep disordered breathing" and "may aid in the diagnosis of sleep disordered breathing." It also produces a report for the HCP to aid in diagnosis, indicating its diagnostic function.
No
The device description clearly states it includes hardware components such as a recorder, sensors (pressure, oximetry, effort), a nasal cannula, and a tablet. While software is involved in data processing and user interface, it is not a software-only device.
Based on the provided information, this 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. They are used to examine these samples outside of the body.
- Device Function: The MATRx plus records physiological data directly from the patient's body during sleep (respiratory nasal airflow, snoring, blood oxygen saturation, pulse, respiratory effort, body position). It does not analyze samples taken from the body.
- Intended Use: The intended use is to aid in the diagnosis and assessment of sleep disordered breathing by recording physiological signals, not by analyzing biological samples.
Therefore, the MATRx plus falls under the category of a medical device that collects physiological data from the patient, rather than an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The device is indicated for use by the Health Care Professional (HCP), where it may aid in the diagnosis and assessment of sleep disordered breathing for adult patients.
MATRx plus records the following data: patient respiratory nasal airflow, snoring, blood oxygen saturation, pulse, respiratory effort and body position during sleep.
The device uses these recordings to produce a report for the HCP that may aid in the diagnosis of sleep disordered breathing. The device is intended for home and hospital use under the direction of a HCP.

Device Description
The MATRx plus is a new ventilatory effort recorder device. The MATRx plus recorder is a 5-channel battery-powered respiratory pressure sensor and oximetry system. MATRx plus provides recordings of respiratory pressure, respiratory effort, pulse rate, oxygen saturation, snoring and body position during sleep. The physician prescribed device is worn on the patient's abdomen attached to a reusable effort belt and all relevant respiratory information during sleep is collected via nasal cannula, pulse oximetry module and respiratory effort sensor. The disposable plastic nasal cannula is connected to the MATRx plus recorder and fixed at the patient's nose. The cannula is dual lumen and functions to individually sample the pressure from each naris. The oximetry sensor is fixed at the patient's finger and connects directly to the device. The Recorder receives input from the sensors and wirelessly transmits the data to a bedside Tablet during the study.
The Tablet is set up through a connection to the web portal by the Health Care Professional (HCP) prior to deploying the device to the patient for use in the home. The Tablet runs the MATRx plus application according to the selected study type, records and stores the data. The MATRx plus application on the Tablet is also used to guide the user through the set up and conduct of the study through a stepwise user interface. At the end of a recording the Tablet advises the patient if sufficient data for analysis were recorded during the night.
After recording, the MATRx plus must be returned to the HCP. The data are automatically uploaded to the secure Portal where they can be accessed and downloaded to the Data Viewer. The Data Viewer can generate a report with the recorded and analyzed data (respiratory pressure, respiratory effort, pulse rate, oxygen saturation) to aid in diagnosis.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Testing Summary:
Design and system verification testing included, among others, mechanical and environmental testing according to IEC 60601-1-11:2010, electrical safety testing according to IEC 60601-1:2005+1 and EMC testing according to IEC 60601-1-2:2007 has been performed. Reprocessing validation testing was completed. A comparison of all performance characteristics for the oximeter and other sensor inputs was completed using bench testing to substantiate equivalence. Autoscoring algorithm for ODI was compared with the Snore SAT monitor output (K002159) on data from 179 patients. Software on the device was verified and validated according to the functionality in conformity to IEC 62304:2006 for software life cycle processes. Test results confirm that the device is in accordance with its specifications.

Bench Testing Summary:
Design and system verification testing included, among others, mechanical and environmental testing according to IEC 60601-1-11:2010, electrical safety testing according to IEC 60601-1:2005+1 and EMC testing according to IEC 60601-1-2:2007 has been performed. Reprocessing validation testing was completed. A comparison of all performance characteristics for the oximeter and other sensor inputs was completed using bench testing to substantiate equivalence. Autoscoring algorithm for ODI was compared with the Snore SAT monitor output (K002159) on data from 179 patients. Software on the device was verified and validated according to the functionality in conformity to IEC 62304:2006 for software life cycle processes. Test results confirm that the device is in accordance with its specifications.
Biocompatibility:
All body contacting components have been cleared in previous 510K devices.
