Description of the PAH-S1-3800
Design Description
The PAH-S1-3800 Hyperbaric Chamber System is a Class B monoplace hyperbaric chamber designed to treat one patient up to a maximum operating pressure of 3 Atmospheres Absolute (ATA) or 29.4 pounds per square inch gauge (PSIG). The chamber may be pressurized with either oxygen or air. Whichever gas is chosen for pressurizing the chamber atmosphere, the opposite gas can automatically be supplied to an alternative breathing device inside the chamber.
The PAH-S1-3800 Hyperbaric Chamber System is designed and fabricated in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, Pressure Vessels; ASME PVHO-1 (American Society of Mechanical Engineers-Pressure Vessels for Human Occupancy); and, NFPA 99: Health Care Facilities. The overall external length of the chamber is 2500mm (approximately 98.4 inches). Its internal diameter is 965mm (approximately 38 inches). The chamber is constructed by half-steel and half-acrylic tube. A low-voltage intercommunication system provides communications between a patient inside the chamber and the operator outside the chamber. The system is designed and installed in accordance with NFPA 99, Chapter 14 (2012 edition) with maximum power to the speaker limited by the intercom circuitry to 250 mW at 1.4 volts (NFPA 99, Chapter 14 limit is 4W and 28 volts).
A moveable control panel contains the primary mechanisms for safe function of the chamber. Pressurization is achieved via a simple pneumatic control system that does not require electricity. Numerous penetrators are provided to allow the user to connect approved patient monitoring devices or deliver fluids during treatment. A computer data-logger installed on the chamber allows real-time treatment profiles and graphs to be downloaded for accurate documentation.
Patients enter and exit the chamber by lying down on a retractable gurney. The hydraulic adjustable height gurney contains a wide-dished bed fitted with a comfortable fire retardant foamed mattress. An integrated adjustable backrest provides increased comfort during treatment.
The chamber door is equipped with a dual safety-lock and safety switch for pressurization. No gas is supplied to the chamber console until the chamber door is latched closed and a pin inserted into the upper door cam. Once the door is secure, an automatic 1 PSI of gas automatically begins to circulate inside the chamber. This gentle flow is not sufficient to immediately pressurize the chamber, however it does hasten the exchange of the ambient 79% nitrogen one atmosphere already hovering within the chamber.

Intended Use
It is the expressed, intended use of the Pan-America Hyperbarics PAH-S1-3800 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 UHMS is the professional medical organization chartered with setting the standards of care defining the appropriate use of hyperbaric oxygen. More specifically, the UHMS publishes a listing of medical conditions that have been clearly established as appropriate primary or adjunctive use of hyperbaric oxygen (HBO). The disorders on the list have been scientifically validated and verified through extensive data collection. It should be noted that the list is dynamic. Based on the strength of the scientific data, disorders are both added and removed from the list, depending on the outcomes of scientific pursuit.
The Pan-America Hyperbarics PAH-S1-3800 Hyperbaric Chamber System is designed to be installed and operated in medical facilities as defined by the NFPA 99, Health Care Facilities, Chapter 14, Hyperbaric Facilities (2012). Further, this system is intended to be operated only by medical personnel specifically trained in the appropriate use of HBO and the safe operation of all related equipment such as the hyperbaric chamber.
Design Function
The PAH-S1-3800 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 PAH-S1-3800 Hyperbaric Chamber System is a Class B monoplace hyperbaric chamber. It is designed to treat one patient at a time up to a maximum operating pressure of 3 Atmospheres Absolute (ATA) or 29.4 pounds per square inch gauge (PSIG). The chamber may be pressurized with oxygen or air. Patients treated in the chamber may breathe the gas contained within the chamber atmosphere or through a simple mask.

The adjustable control panel allows all chamber functions to be conveniently controlled and monitored. Numerous penetrator ports are provided for connecting a variety of ancillary medical equipment. A built-in safety mechanism prevents pressurization until the chamber door is securely closed. Patient loading is easily performed by a retractable gurney.
The PAH-S1 Hyperbaric Chamber System is designed and fabricated in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, Pressure Vessels; ASME PVHO-1 (American Society of Mechanical Engineers-Pressure Vessels for Human Occupancy), and NFPA 99 Standard for Healthcare Facilities. The chamber’s hull is constructed of carbon steel. The clear tube is made of acrylic and attached to the hull by four stainless steel connection rods and bolts. The communication system is intrinsically safe and designed to operate on rechargeable battery power.
