Intended Use

The PAH-M3+1 Hyperbaric Chamber System is intended to be procured and used by physicians to treat a variety of medical conditions that respond to hyperbaric oxygen. The Undersea & Hyperbaric Medical Society (UHMS) produces a list of medical conditions that have been identified for the appropriate primary or adjunctive use of hyperbaric oxygen. These approved conditions include: air or gas embolism; carbon monoxide poisoning and smoke inhalation; clostridial myonecrosis (gas gangrene); crush injury, compartment syndrome and other acute traumatic ischemias; decompression sickness; enhanced healing of selected problem wounds: exceptional blood loss anemia: necrotizing soft tissue infections: osteomyelitis (refractory); radiation tissue damage (osteoradionecrosis); compromised skin flaps and grafts; thermal burns; and, intracranial abscess. Aggressive research into the beneficial effects of hyperbaric oxygen, when appropriately applied, will result in additional medical conditions being added to the list of indications by the UHMS. It is the expressed, intended use of the Pan-America Hyperbarics' PAH-M3+1 Hyperbaric Chamber System to provide therapy to those patients with selected medical conditions that have been determined to respond to the application of hyperbaric oxygen. As a Class II prescriptive device, it is further intended for physician involvement in its procurement and routine use. The conditions listed as appropriate for the use of HBO in the current edition of the Hyperbaric Oxygen Therapy Committee Report (1999) are as follows: 1. Air or gas embolism 2. Carbon monoxide poisoning and carbon monoxide poisoning complicated by cyanide poisoning 3. Clostridial myositis and myonecrosis 4. Crush injury, compartment syndrome, and other acute traumatic ischemias 5. Decompression sickness 6. Enhanced healing of selected problem wounds 7. Exceptional blood loss anemia 8. Necrotizing soft tissue infections 9. Osteomyelitis (refractory) 10. Delayed radiation injury (soft tissue and bony necrosis) 11. Skin grafts and flaps (compromised) 12. Thermal burns 13. Intracranial abscess

Device Description

The PAH-M3+1 Hyperbaric Chamber System is a Class A multiplace hyperbaric chamber designed to treat up to 4 patients at up to a maximum operating pressure of 3 Atmospheres Absolute (ATA) or 29.4 pounds per square inch gauge (psig). The chamber uses compressed air as the pressurization gas and 100% oxygen as the hyperbaric treatment gas. The PAH-M3+1 Hyperbaric Chamber System is 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); and, NFPA 99, Health Care Facilities, Chapter 19, Hyperbaric Facilities (Chapter 20, 2002 Edition). The overall external length of the chamber is 4500mm (approx. 14.76 ft). Its internal diameter is 1016mm (approx. 40 inches). There are two compartments: main compartment and transfer compartment. Three (3) removable seats and one fixed (1) seat are installed in main compartment and transfer compartment respectively. Two independent fire suppression systems, water deluge system and handline system, are installed in accordance with the requirements of NFPA 99, Chapter 19 (Chapter 20, 2002 Edition). Pressurization is provided by compressed air with 100% oxygen administered to the patient by using properly fitting oronasal masks or head tents. A lowvoltage patient intercommunication system designed and installed in accordance with NFPA 99. Chapter 19 (Chapter 20, 2002 Edition) and provides communications between the patients in the chamber and the outside chamber operator. A Teledyne TED-191 oxygen analyzer is installed to monitor the concentration of oxygen inside the chamber continually. The system consists of an operator control console that contains all of the controls and connection points. Single operator chamber pressure control is achieved via a simple manual pneumatic control. A penetrator plate is provided in the vessel wall to allow user supplied medical monitoring leads, etc., to be used as required. The patients are loaded and unloaded by a retractable gurney, which is equipped with a sliding transport chair. When supine position is needed, a sliding bunk will be used instead. The chamber is also equipped with safety switch for pressurization. There is no gas supply before the chamber's door is closed and secured thoroughly.

AI/ML (Artificial Intelligence / Machine Learning)

No
The document describes a hyperbaric chamber system with manual controls and standard safety features. There is no mention of AI or ML in the intended use, device description, or performance studies sections.

Therapeutic

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "intended to provide therapy to those patients with selected medical conditions that have been determined to respond to the application of hyperbaric oxygen."

Diagnostic

The device is a hyperbaric chamber system used to provide therapy for various medical conditions by delivering hyperbaric oxygen, not to diagnose conditions.

SaMD (Software as a Medical Device)

The device description clearly details a physical hyperbaric chamber system with hardware components such as a pressure vessel, seats, fire suppression systems, oxygen analyzer, control console, and gurney. It is not solely software.

IVD (In Vitro Diagnostic)

Based on the provided text, the PAH-M3+1 Hyperbaric Chamber System is not an In Vitro Diagnostic (IVD) device.

Here's why:

IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
Device Function: The PAH-M3+1 Hyperbaric Chamber System is a therapeutic device. It is used to treat patients by exposing them to hyperbaric oxygen, which is a physical therapy applied directly to the patient's body.
Intended Use: The intended use clearly states that the device is used to "treat a variety of medical conditions that respond to hyperbaric oxygen." This is a therapeutic application, not a diagnostic one based on analyzing samples.
Device Description: The description details a pressure vessel designed for human occupancy, with systems for pressurization, oxygen delivery, communication, and safety. These are all components of a therapeutic chamber, not an analytical device for specimens.

Therefore, the PAH-M3+1 Hyperbaric Chamber System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.
