Figure 1 – Components of the MATRx plus System
SYSTEM COMPONENTS
The components of the MATRx plus System include a Tablet, a Recorder and the following sensors: Effort Belt,
Nasal Cannula, Pulse Oximeter and an MP with Titration Trays (see Figure 1). These body-mounted sensors are
used to collect information about the patient’s respiratory pattern while monitoring oxygen saturation and heart
rate. The device interacts wirelessly to upload the data collected from the study to the Patient Information Portal
where a Data Viewer is used to facilitate analysis, interpretation and report generation.

Static Study
During this type of study night, the system will move the mandible to the target protrusive
position at the calculated during the first night, and will refine the position only as needed.
The majority of patients will only require two OA Study nights. If a third night is needed, it will be
another Static Study at a new target protrusive position.
For a detailed overview on the Principal of Operation during an OA Study, Refer to Appendix 3.
The OA Study workflow is as follows:
Titration Trays are prepared and the MATRx plus System is set-up for the patient (i.e. patient data
and study type are entered)
OA Study is performed and the data is automatically uploaded to the Patient Information Portal
for review
A custom oral appliance is prescribed if patient is predicted to be a responder to OAT
