SIGMA II

The SIGMA II Dualplace Hyperbaric System is designed to accommodate two seated patients simultaneously, or one supine patient and a seated attendant. The SIGMA II delivers exceptional performance for hospitals with moderate patient treatment requirements. The SIGMA II bridges the gap between the clinical limitations of the monoplace system and the major investment required for larger multiplace chambers.

The alternate configuration of the SIGMA II does not include the entry lock and the treatment compartment is fitted with three seats so that three seated patients can be treated simultaneously (SIGMA II/3). If an entry lock is added, a fourth seat can be placed in that compartment, making it a SIGMA II/4.

Flexibility

The SIGMA II features a spacious 40 inch internal diameter acrylic treatment compartment which allows for increased patient accessibility and monitoring. The optional entry lock permits attendants and physicians to enter and leave the system as needed. The ability to position the patient in a reclining seat as well as in a supine position on a gurney is an important SIGMA II distinction. Pressurized with air instead of oxygen, the SIGMA II utilizes a built-in breathing system (BIBS) which gives the operator the ability to independently adjust each patient's oxygen supply.

Patient Comfort

The SIGMA II's spacious interior increases patient treatment acceptance by reducing the likelihood of confinement anxiety. Patient comfort is also enhanced by the cushioned, reclining chairs. The acrylic main compartment allows the patient excellent vision and the ability to enjoy entertainment (TV/video system) during the treatment period.

Safety

The SIGMA II is a Class A hyperbaric chamber as defined by the National Fire Protection Association (NFPA). The standard fire suppression system is activated at the control console. Patients and attendants are supplied with breathing oxygen gases separate from the system environment. A standard oxygen monitor checks the concentration of oxygen within the compartment.

Patient Accessibility

The entry lock permits a physician or attendant to enter or leave the system during treatment, allowing for treatment of acute patients. The SIGMA II also allows for medical monitoring of critically ill patients. The optional medical lock is a convenient way to pass refreshments or medical supplies in and out of the system.

Cost-Effectiveness

The SIGMA II reduces staffing requirements per patient while increasing the number of patients that can be treated simultaneously. The built-in breathing system (BIBS) provides optimal oxygen consumption per patient.

Building Service Requirements

The following requirements must be met for proper operation of the SIGMA II Dualplace Hyperbaric System.

• Building must adhere to construction requirements specified in NFPA 99, Health Care Facilities.
• Optimal patient comfort is achieved if the room is maintained at 68°-72° F (20°-22.2° C).
• Breathing Quality Air: Main Air - minimum pressure of 60 psi at 40 scfm (4.13 bar @ 1130 lpm). Stand-by Air - minimum pressure of 50 psi at 7.4 scfm (3.4 bar @ 210 lpm).
• Oxygen Supply: Minimum pressure of 50 psi @ 7.4 scfm (3.4 bar @ 210 lpm). Pressure gauge and shut-off valve installed in accessible location. Line and all components installed in accordance with NFPA specifications.
• Stand-by Air Supply: A minimum of 210 lpm if breathing quality air at a minimum pressure of 50 psi must be supplied to the chamber as stand-by (emergency breathing) air. The air must be taken from a source other than the main air supply, either high pressure cylinders or from existing hospital air supplies if a separate dedicated compressor system is used.
• Exhaust Line: 1½” nominal diameter copper (minimum). The exhaust line should be run to the exterior of the building no less than eight feet above the chamber level in an area where no potential source of ignition or fuel exists. The exhaust line should be installed so as to obviate entry of rain or foreign objects.
• Fire Suppression System: (A) Fire suppression deluge water - flow of 80 gpm @ minimum pressure of 110 psi (B) Hand line water, from a separate, independent source - flow of 10 gpm @ minimum pressure of 85 psig.
• Electrical Service: 110 VAC outlet for communication system power supply and maintaining charge on 12 VDC backup battery.
• Chamber Ground: Chamber grounding should be in accordance with NFPA 99, NFPA 70, National Electrical Code, grounding and local electrical codes. Additional grounding instructions shall be provided as required.
• The SIGMA II is supplied with all necessary hoses and fittings to easily connect to the customer-provided services described above. All building services should terminate within three feet of the foot of the hyperbaric system.
