The Sleep Lab Mask is the only variant that is validated and intended for multipatient reprocessing and must be reprocessed if reused between patients.
Arcadia Mask System
The Arcadia has two product variants:
· Arcadia mask is intended for single-patient reuse in the home environment.
· Arcadia SLM (Sleep Lab Mask) variant is intended for multi-patient reuse in the hospital/institutional environment.
These masks are intended for patients weighing more than 66 lb (30kg), who have been prescribed non-invasive CPAP or bi-level positive airway pressure (PAP) therapy. The Sleep Lab Mask is the only variant that is validated and intended for multi-patient reprocessing and must be reprocesssed if reused between patients.
The AirFit F30i, AirFit F30i NM and Arcadia mask systems are full-face conduit masks intended for use with Continuous Positive Airway Pressure (CPAP) and/or Bi-Level devices are used for the treatment of Obstructive Sleep Apnea (OSA) and/or non-life supporting ventilatory support. Both treatments deliver pressurized air from a flow generator to the patient. Such delivery of pressurized air relies on the Patient Interface; commonly known as the mask. Full face masks are a common type of Patient Interface (Mask) and are known to efficaciously support the delivery of pressurized air by providing a seal around the patient's nose and mouth.
The AirFit F30i, AirFit F30i NM and Arcadia mask systems each have two product variants:
- . AirFit F30i Mask/ AirFit F30i NM Mask/ Arcadia Mask: This is the home use variant that is intended for single patient re-use.
- . AirFit F30i SLM/ AirFit F30i NM SLM/ Arcadia SLM (sleep lab mask): This is intended for multipatient re-use and must be reprocessed if reused between patients using the disinfection guide
The AirFit F30i, AirFit F30i NM and Arcadia mask systems are made up of the following four main component assemblies: Cushion, conduit frame, elbow and headgear. The cushion and conduit frame are available in various sizes to allow for adequate mask fit over the intended patient population.
The AirFit F30i, AirFit F30i NM and Arcadia mask systems are prescription devices supplied non-sterile.
The provided text does not contain detailed information about the acceptance criteria or a specific study that proves the device meets those criteria in the format requested. The document is a 510(k) summary and FDA clearance letter, which outlines the device's substantial equivalence to a predicate device based on various performance and safety tests. However, it does not provide the specific "acceptance criteria" (e.g., minimum sensitivity, specificity, or accuracy thresholds) or the detailed methodology and results of a single study with the requested metrics.
Instead, the document lists several non-clinical data submitted, which include performance and safety tests in accordance with ISO standards and other bench tests. The conclusion states that "Non-clinical verification and validation assessment/testing demonstrated that AirFit F30i NM and Arcadia mask systems met all intended performance requirements." and "Verification confirmed that the new device met the predetermined acceptance criteria and the performance is substantially equivalent to the previously cleared predicate AirFit F30i mask system (K183512)."
Therefore, I can extract the types of tests performed and the comparison to the predicate device, but I cannot fill in the table or answer all sub-questions as the specific numerical acceptance criteria and a single "study" proving it with the requested detail are not present.
Here's what can be extracted based on the provided text, with an explanation for missing information:

The Oran Park mask is intended for use in the home or hospital/institutional environment on patients weighing more than 661b (30kg), who have been prescribed non-invasive CPAP or bi-level positive airway pressure (PAP) therapy.
Only the Sleep Lab Mask (SLM) variant is intended and validated for multi-patient reuse and must be reprocessed if reused between patients.
The Oran Park Mask is an accessory to deliver air flow and positive air pressure generated by positive airway pressure (PAP) devices such as CPAP or bi-level flow generator systems to the patient's airway, for the treatment of Obstructive Sleep Apnea (OSA) or ventilator support (non-life support). It delivers the treatment pressure from the source device to the patient's upper airway by providing an air seal between the PAP device and under the patient's nose and mouth.
There are 2 variants to the Oran Park Mask:
- . Oran Park Mask (Home Use) Intended for single patient re-use (SPMU) for home use. It is configured with a diffused venting port located on the elbow, known as the QuietAir elbow.
- . Oran Park SLM (Sleep Lab Mask)
Intended for multi-patient re-use (MPMU) and must be reprocessed if reused between patients. It is configured with a non-diffused venting port located on the elbow, known as the Multihole elbow.
The Oran Park mask comprises of 4 sub-assemblies: headgear, frame, cushion and elbow. The venting ports and anti-asphyxia valve are incorporated into the elbow assembly. There are four magnets incorporated in the Oran Park mask – two magnets in the frame assembly and 2 magnets in the lower headgear clips – with a magnetic field strength up to 400 mT. The mask help facilitate attaching and detaching the headgear to the mask frame when regularly fitting the mask for use. The cushion and headgear are available in various sizes to fit a wide patient population. Soft wraps, which are attached to the Oran Park mask frame, are available as an optional accessory for patient's comfort.
The Oran Park mask is a prescription device and is supplied non-sterile.
The Oran Park Mask is a medical device accessory used to deliver airflow and positive air pressure from PAP devices for the treatment of Obstructive Sleep Apnea or ventilator support.

2. Sample Size Used for the Test Set and Data Provenance:
The document describes non-clinical verification and validation testing. This type of testing typically involves bench tests on manufactured devices rather than studies on human subjects. Therefore, the concept of "test set" in the context of patient data, sample size of patients, and data provenance (country of origin, retrospective/prospective) is not applicable here. The tests are performed on the device prototypes or production samples in a laboratory setting. No information is provided regarding the number of units tested for each non-clinical test.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This information is also not applicable as the study described is non-clinical, involving engineering and performance testing against established standards and predicate device performance, not clinical interpretation requiring expert ground truth establishment.
4. Adjudication Method (2+1, 3+1, none) for the Test Set:
This information is not applicable for the same reasons as points 2 and 3. Non-clinical bench testing does not involve adjudication methods used in clinical studies.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
This is not applicable. The device, an Oran Park Mask, is a physical patient interface for respiratory therapy. It is not an AI-powered diagnostic or assistive tool, so an MRMC study comparing human reader performance with and without AI assistance would not be relevant.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done:
This is not applicable. The device is a physical mask, not an algorithm.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.):
For the non-clinical tests, the "ground truth" or reference for acceptance was primarily:
- International Standards: Specifically ISO 17510:2015 (Medical devices – Sleep apnoea breathing therapy – Masks and application accessories), ISO 10993 series (Biocompatibility), ISO 18562 series (Biocompatibility of breathing gas pathways), ISO 5356-1 (Conical connectors), etc.
- Performance of the Predicate Device: The AirFit F20 (K153563) served as a direct comparison for various parameters to establish substantial equivalence.
- Predetermined Acceptance Criteria: These are likely internal specifications derived from the standards and predicate device performance, ensuring safety and effectiveness.
8. The Sample Size for the Training Set:
This is not applicable as there is no "training set" in the context of non-clinical device testing for a physical mask. Device design and validation follow engineering and regulatory processes, not machine learning training.
9. How the Ground Truth for the Training Set Was Established:
This is not applicable for the reasons stated in point 8.

| - Sound pressure level | 14 dBA | 17 dBA | Equivalent. Similar to sound power, a 3 dBA increase in sound pressure is often considered acoustically equivalent or minor in regulatory context for patient comfort if within acceptable ranges, not raising new safety or effectiveness concerns. |
| Biocompatibility | Materials used in predicate | New materials for nasal cushion and conduit frame sleeve | Equivalent. All new materials have been included in previously cleared submissions or underwent biological evaluation as per ISO 10993-1 and ISO 18562-1, meeting the acceptance criteria for biocompatibility. |
| Reprocessing Claims Validation | Single/multi-patient re-use (Scone SLM: 30 cycles) | Single/multi-patient re-use (Whitsundays SLM: 30 cycles) | Identical. Validation performed in accordance with ISO 17664-1 and ISO 17664-2, including cleaning efficacy, disinfection efficacy, residual toxicity, and mechanical integrity testing, ensuring the reprocessing claims are met for the specified use life. |
| Mechanical Integrity | Not explicitly detailed | Met all intended performance requirements | New device completed non-clinical verification and validation testing, including mechanical integrity before and after environmental tests (home cleaning, transportation, storage, operation, free fall, sit test, cleaning, and reprocessing). The acceptance criteria are that the device maintains its mechanical integrity under these conditions. |
2. Sample size used for the test set and the data provenance
The document refers to "non-clinical verification and validation testing" and "bench tests" for performance characteristics. The specific sample sizes for these tests are not provided in the summary.
The data provenance is from bench testing conducted by ResMed Pty Ltd. This is a form of prospective testing, as it involves newly manufactured devices undergoing controlled experiments. The country of origin for the company is Australia.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not provided in the document. The studies are primarily engineering and performance tests against recognized standards (e.g., ISO, rather than clinical studies requiring expert ground truth for interpretation like imaging).
4. Adjudication method for the test set
Not applicable. The evaluations are based on quantifiable measurements against established standards (e.g., flow rates, pressure drops, CO2 levels) rather than subjective assessments requiring adjudication.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable. The device is a medical mask and not an AI-powered diagnostic or assistive tool for human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device is a physical medical mask, not an algorithm.
7. The type of ground truth used
The "ground truth" for the non-clinical tests is established by international standards such as ISO 17510:2015, ISO 18562, ISO 10993, and ISO 17664. These standards define the acceptable performance limits and methodologies for testing. For some parameters like physical dead space, the "ground truth" is the measured value of the predicate device, against which the new device's measurements are compared for equivalence.
8. The sample size for the training set
This is not applicable. The device is a physical medical mask, not a machine learning model that requires a training set.
9. How the ground truth for the training set was established
