Indications for Use
The monoplace hyperbaric chamber is indicated for use for the following clinical medical conditions in accordance with guidelines established by the Undersea and Hyperbaric Medical Society, as follows: - Air or Gas Embolism - Carbon Monoxide / Smoke Inhalation - Compromised Skin Grafts and Flaps - Crush Injuries / Acute Traumatic Ischemias - Decompression Sickness - Enhanced Healing in Selected Problem Wounds - Exceptional Blood Loss (Anemia) - Gas Gangrene (Clostridial Myonecrosis) - Intracranial Abscess - Necrotizing Soft Tissue Infections - Radiation Tissue Damage (Osteoradionecrosis) - Refractory Osteomyelitis - Thermal Burns
Device Story
Monoplace hyperbaric chamber for single-patient hyperbaric oxygen therapy (HBOT). Input: compressed pure oxygen or breathing air. Operation: patient breathes oxygen (via chamber atmosphere or hood/mask) at elevated pressure to promote tissue oxygenation. Chamber consists of ASME-certified pressure vessel with acrylic cylinder; pneumatic control system (no electrical/electronic components). Used in clinical settings; operated by trained personnel. Output: pressurized environment for therapeutic oxygen delivery. Benefits: enhanced healing for specified medical conditions. Differences from predicate include larger acrylic cylinder (40" vs 25.25" diameter), moveable arm-mounted pneumatic controls, and fiberglass cosmetic covers.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on technological characteristics, design standards (ASME/PVHO-1), and identical treatment methodology to the predicate device.
Technological Characteristics
ASME pressure vessel; acrylic plastic cylinder (PVHO-1 compliant); pneumatic control system (no electrical/electronic components); 40" inside diameter cylinder; fiberglass cosmetic covers; moveable arm-mounted control box. Pressurization via compressed oxygen or breathing air.
Indications for Use
Indicated for patients requiring hyperbaric oxygen therapy for conditions including air/gas embolism, carbon monoxide/smoke inhalation, compromised skin grafts/flaps, crush injuries/acute traumatic ischemias, decompression sickness, problem wounds, anemia, gas gangrene, intracranial abscess, necrotizing soft tissue infections, radiation tissue damage, refractory osteomyelitis, and thermal burns.
Regulatory Classification
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).
Predicate Devices
- SIGMA I Monoplace Hyperbaric Chamber (K832127)

## SIGMA Plus Monoplace Hyperbaric Chamber Summary of Safety & Subject: Effectiveness Information
Gentlemen:
This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.
Substantial Equivalence: The Perry Baromedical Corporation SIGMA Plus Monoplace Hyperbaric Chamber is substantially equivalent to the Perry Baromedical Corporation SIGMA I Monoplace Hyperbaric Chamber, [510(k) K832127]. The SIGMA Plus has the same intended use and the same technological characteristics as the SIGMA I predicate device. The scope and operation of the SIGMA Plus is identical to that of the SIGMA I in the following areas:
- The critical component of both systems consists of an ASME pressure vessel that is l designed, fabricated, and tested in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division I; and ASME PVHO-1, Safety Standard for Pressure Vessels for Human Occupancy.
- The pressure vessel consists of certified metal components constructed of materials in 2 conformance with the ASME Boiler and Pressure Vessel Code, Section II - Materials. In addition to the metal parts, the pressure retaining boundary consists of an acrylic plastic cvlinder, designed and constructed to the requirements of ASME PVHO-1, Safety Standard for Pressure Vessels for Human Occupancy.
- The pressure vessel is protected from accidental over pressurization by an ASME "UV" 3 stamped pressure relief valve.

SIGMA Plus 510(k) Summary Page 2 of 3
- The medium used for pressurization of the chamber is either compressed pure oxygen or 4 compressed breathing air.
- Treatment capacity of the chamber is one (1) patient. 5
- Communication between the patients / attendants is through an intrinsically safe 6 communications system.
- The SIGMA I and SIGMA Plus chambers are used to provide Hyperbaric Oxygen 7 Therapy, prescribed by a licensed physician, where medical grade oxygen is administered to patients while under pressure; either by the patient breathing the chamber atmosphere, (when pressurized with oxygen), or by the patient breathing oxygen from a breathing hood or breathing mask, (when pressurized with breathing air); The breathing of oxygen at elevated pressure promotes the movement of oxygen into the patient's tissues.
- The chamber pressurization and depressurization control system is completely pneumatic, 8 with no electrical or electronic components.
Differences do exist between the SIGMA Plus and the SIGMA I Monoplace chamber; they include:
- l The PVHO-1 acrylic cylinder in the SIGMA Plus chamber is 40" inside diameter, and the P VHO-1 acrylic cylinder in the SIGMA I chamber is 25.25" inside diameter. Both acrylic cylinders are designed with a 20 to 1 safety factor.
- 2 The pneumatic controls for the SIGMA Plus chamber are mounted in a control box that is suspended from a moveable arm, allowing use from either side of the chamber; while the pneumatic controls for the SIGMA I chamber are mounted in a panel on one side of the chamber.
- 3 The SIGMA Plus Monoplace Hyperbaric Chamber has painted fiberglass cosmetic covers on the sides and ends of the chamber; the SIGMA I Monoplace Hyperbaric Chamber has a wheeled aluminum support chassis.
