Indications for Use
The SIGMA II Dualplace Hyperbaric Chamber is used to provide Hyperbaric Oxygen Therapy, prescribed by a licensed physician, where medical grade oxygen is administered to patients while under pressure, by the patient breathing oxygen from a breathing hood or breathing mask with the chamber pressurized with breathing air. The breathing of oxygen at elevated pressure promotes the movement of oxygen into the patient's tissues.
Device Story
Multiplace hyperbaric chamber for two patients; provides hyperbaric oxygen therapy (HBOT). Input: compressed breathing quality air for chamber pressurization; medical grade oxygen for patient inhalation via hood or mask. Operation: ASME-certified pressure vessel; pneumatic control system for pressurization/depressurization; intrinsically safe communication system; fire suppression/extinguishing systems. Used in clinical settings; operated by trained personnel. Physician prescribes HBOT; patient breathes oxygen at elevated pressure to promote tissue oxygenation. Enhances ease of operation via moveable control arm and pedestal-mounted breathing system controls compared to predicate. Benefits: facilitates treatment of conditions like decompression sickness, wounds, and infections.
Clinical Evidence
No clinical data. Bench testing only; device relies on established ASME pressure vessel standards and substantial equivalence to a previously cleared predicate device.
Technological Characteristics
ASME pressure vessel (Section VIII, Div 1; PVHO-1); acrylic cylinder (40" ID, 65" length, 20:1 safety factor); pneumatic control system (no electrical/electronic components); intrinsically safe communication; fire suppression system; fiberglass cosmetic covers. Pressurization via compressed air.
Indications for Use
Indicated for patients requiring hyperbaric oxygen therapy for: Air or Gas Embolism, Carbon Monoxide/Smoke Inhalation, Compromised Skin Grafts/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, 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).

## SIGMA Plus / II Multiplace Hyperbaric Chamber Summary of Safety & Subject: Effectiveness Information - Amended as of January 15, 1999
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 SIGNA Plus / II Multiplace Substantial Equivalence. "The Perry Baromedical Corporation Corporation SIGMA Hyperbaric Chamber is substantially oquili K862198/A]. The SIGMA Plus / Il has the same If Dualplace Tryperbarte Chamoer, [220]. Investeristics as the SIGMA II predicate device.
Intended use and the same technological characteristics as the SIGMA II in in The scope and operation of the SIGMA Plus/ II is identical to that of the SIGMA II in the following areas:
- The critical component of both systems consists of an ASME pressure vessel that is l I he critical component of tested in accordance with the requirements of the ASME designed, labricated, and testode, 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 The pressure vesser consists of occession Pressure Vessel Code, Section II - Materials. Contornatice with the rolling boundary consists of an actylic of an actylic 1 in addition to the mean parts, 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) K983648 Amended Summary Page 2 of 3
- The medium used for pressurization of the chamber is compressed breathing quality air. 4
- Treatment capacity of the chamber is two (2) patients. 5
- Communication between the patients / attendants is through an intrinsically safe б communications system.
- The SIGMA II and SIGMA Plus/ II 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, by the patient breathing oxygen from a breathing hood or breathing mask with the chamber 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 8 pneumatic, with no electrical or electronic components.
- Both chambers are Class "A" multiplace hyperbaric systems, with Fire Suppression 9 Systems and independent hand line fire extinguishing systems.
Differences do exist between the SIGMA Plus/ II and the SIGMA II Dualplace chamber; they include:
- The PVHO-1 acrylic cylinder in the SIGMA Plus / II chamber is 40" inside diameter l and 65" long, and the PVHO-1 acrylic cylinder in the SIGMA II chamber is 40" inside diameter by 85" long. Both acrylic cylinders are designed with a 20 to 1 safety factor.
- The pneumatic controls for the SIGMA Plus / II chamber are mounted in a control 2 box that is suspended from a moveable arm, allowing use from either side of the chamber; while the pneumatic controls for the SIGMA II chamber are mounted in a console panel mounted on one side of the chamber.
{2}------------------------------------------------
SIGMA Plus 510(k) K983648 Amended Summary Page 3 of 3
- The SIGMA Plus/ II Multilace Hyperbaric Chamber has painted fiberglass cosmetic 3 covers on the sides and ends of the chamber; the SIGMA II Dualplace Hyperbaric Chamber has aluminum side cosmetic covers.
- The Built-In Breathing System controls for the SIGMA Plus / II are mounted in a 4 pedestal mounted moveable control panel, allowing positioning to suit the operator location. The SIGMA II Built-In Breathing System controls are mounted in the control console positioned at the side of the chamber.
- The SIGMA II Dualplace chamber is available with an Entry Lock and a Medical Lock 5 feature, which are not offered with the SIGMA Plus / II.
The changes to the SIGMA II system resulting in the SIGMA Plus/ II Dualplace Hyperbaric Chamber enhance its ease of operation, and do not adversely effect the safety and effectiveness of the device. The basic treatment method is identical, only the chamber acrylic window length size has been changed
