The Aer X oxygen concentrator device is used on a prescriptive basis by patients requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient. The Aer X may be used in home, institution, vehicle and various mobile environments.

The Aer X oxygen concentrator utilies a molecular sieve and a differential pressure swing adsorption methodology to separate the gases in ambient air. The device takes the room air and concentrates the oxygen portion to produce a pulse of oxygen between 87-94% in purity. When the patient inhales, the device senses the pressure change and is triggered to release the oxygen pulse. In between breaths, the device regenerates an oxygen pulse and waits for the next inhalation breath before dispensing it

The provided document is a 510(k) Pre-Market Notification for a medical device, the Aer X Portable Oxygen Concentrator. It does not contain the specific details of a clinical study demonstrating the device's performance against detailed acceptance criteria that would typically be found in a clinical trial report.

Instead, this document focuses on demonstrating substantial equivalence to a predicate device (VBOX Trooper) through bench testing and technical comparison, which is a different regulatory pathway than requiring a full clinical effectiveness study with defined acceptance criteria for effectiveness.

Therefore, many of the requested elements for a study proving the device meets acceptance criteria are not present in this type of submission. However, I can extract the information available regarding the functional and performance aspects of the device and how conformity was demonstrated.

Here's an attempt to answer your questions based on the provided text, indicating where information is not available:

1. Table of acceptance criteria and the reported device performance

The document doesn't explicitly state "acceptance criteria" for a clinical performance study. Instead, it lists technical specifications and demonstrates that the device meets these specifications which are consistent with the predicate and industry standards.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

This document describes bench testing, not a human-subject clinical trial.

• Sample Size: Not specified for bench testing, typically involves a small number of production or early-stage devices to verify specifications.
• Data Provenance: Not applicable for bench testing. Bench tests are typically conducted in a laboratory environment, not involving patient data.
• Retrospective/Prospective: Not applicable for bench testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

Not applicable. Bench testing relies on objective measurements against established technical standards, not expert interpretation of results on patient data.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Not applicable, as this was bench testing, not a clinical study requiring adjudication of expert opinions.

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

Not applicable. This device is an oxygen concentrator, not an AI diagnostic tool that would involve human readers.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This device does not involve an "algorithm only" component in the sense of AI or diagnostic interpretation. Its performance is intrinsic to its mechanical and electrical function.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for the performance specifications (e.g., oxygen concentration, flow rate) is defined by technical standards and industry benchmarks for portable oxygen concentrators. Bench testing physically measures the device's output and compares it to these predetermined specifications (e.g., a gas analyzer for oxygen purity, flow meters for flow rate).

8. The sample size for the training set

Not applicable. There is no "training set" as this is not a machine learning or AI-driven device.

9. How the ground truth for the training set was established

Not applicable. There is no "training set."
