The Hyperbaric America Presidential Monoplace Hyperbaric Chamber Systems (Model HA-34 and HA-38) are Class B monoplace hyperbaric chambers designed to treat one patient at up to a maximum operating pressure of 3 Atmospheres Absolute (ATA) or 29,4 pounds per square inch gauge (psig). The chamber uses 100% oxygen as the pressurization gas and patient breathes the oxygen contained inside the chamber as the hyperbaric treatment gas. Air pressurization with oxygen delivery by mask is optional
The Presidential Hyperbaric Oxygen Systems are designed and fabricated in accordance with the requirements of the ANSI/ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, Pressure Vessels; ANSI/ASME-PVHO-1 (American Society of Mechanical Engineers-Pressure Vessels for Human Occupancy, 2007 Edition); and, NFPA 99, Health Care Facilities, Chapter 20, Hyperbaric Facilities, 2005 Edition. The overall external length of both models is 92 inches. The internal diameter of Model HA-34 is 33.5 inches and of Model HA-38 is 38 inches. The chamber is constructed by half-steel and half-acrylic tube. A low-voltage patient intercommunication system designed and installed in accordance with NFPA 99, Chapter 20 and provides communications between the patients in the chamber and the outside chamber operator.
The system consists of an operator control panel that contains all of the controls and connection points. Single operator chamber pressure control is achieved via a simple manual pneumatic control. Spare penetrators are provided to allow user supplied medical monitoring leads, etc., to be used as required. Patient is loaded and unloaded by a retractable qurney. When loading, patient lies down on the fire retardant foamed bunk, aligned to the rails of the chamber and fixes four wheels of the gurney, then push the bunk into the chamber. Unloading the patient with an opposite procedure. The chamber is also equipped with for pressurization. There is no gas supply for pressurization before the chamber's door is closed and secured thoroughly.
The provided text is a 510(k) Notification Summary for a medical device: the Hyperbaric America, LLC, Presidential Monoplace Hyperbaric Chamber Systems. This document is a regulatory submission for premarket notification to the FDA, demonstrating substantial equivalence to predicate devices, rather than a study report proving device performance against acceptance criteria in the typical sense of a diagnostic or AI-driven device.
Therefore, the requested information elements related to the acceptance criteria, study data, ground truth establishment, sample sizes, and expert reviews for such a study are not applicable to this type of document and device. This document describes the device, its intended use, and its adherence to established engineering and safety standards, rather than clinical performance metrics.
Here is a summary of the requested information, noting its applicability to the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Safety and Design Standards Compliance: | |

| NFPA 99, Health Care Facilities, Chapter 20, Hyperbaric Facilities, 2005 Edition | "designed and fabricated in accordance with the requirements" and "designed to be installed and operated in medical facilities as defined by the NFPA 99" |
| Operating Pressure: | |
| Max operating pressure of 3 Atmospheres Absolute (ATA) or 29.4 psig | Device designed to treat one patient at up to a maximum operating pressure of 3 ATA or 29.4 psig |
| Patient Intercommunication: | |
| Low-voltage patient intercommunication system meeting NFPA 99, Chapter 20 standards | "A low-voltage patient intercommunication system designed and installed in accordance with NFPA 99, Chapter 20 and provides communications between the patients in the chamber and the outside chamber operator." |

Note: This document focuses on demonstrating substantial equivalence to predicate devices and adherence to recognized safety and engineering standards for market clearance. It does not present clinical performance data in terms of accuracy, sensitivity, or specificity as would be expected for a diagnostic or AI-driven device.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable. This document is a regulatory submission for a medical device (hyperbaric chamber) and does not involve a "test set" of data in the context of diagnostic performance evaluation or AI model validation. The "study" mentioned here refers to the engineering design and manufacturing process adhering to established standards, rather than a clinical trial with a test set of patient data.
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. "Ground truth" in the context of expert consensus on diagnostic images or outcomes data is not relevant to the approval of a hyperbaric chamber. The "truth" in this context is adherence to engineering codes and safety standards, and the recognized indications for hyperbaric oxygen therapy as established by medical societies.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. There is no "test set" or adjudication process described as this is not a diagnostic device study.
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 a hyperbaric chamber, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This device is a hyperbaric chamber, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for this device's approval is primarily based on:
- Adherence to recognized engineering and safety standards: ANSI/ASME Boiler and Pressure Vessel Code, ANSI/ASME-PVHO-1, and NFPA 99.
- Established medical literature and society recommendations: The conditions suitable for HBO therapy are those listed by "the Undersea & Hyperbaric Medical Society's Hyperbaric Oxygen Therapy Committee Report (2003)."
8. The sample size for the training set
- Not Applicable. This document pertains to a physical medical device, not a machine learning model, so there is no "training set."
9. How the ground truth for the training set was established
- Not Applicable. As there is no training set, this question is not relevant.
§ 868.5470 Hyperbaric chamber.
(a)
Identification. A hyperbaric chamber is a device that is intended to increase the environmental oxygen pressure to promote the movement of oxygen from the environment to a patient's tissue by means of pressurization that is greater than atmospheric pressure. This device does not include topical oxygen chambers for extremities (§ 878.5650).(b)
Classification. Class II (performance standards).
