Sechrist Model 3300E Hyperbaric Chamber with Electronic Control Module Sechrist Industries, Inc., the world’s leading manufacturer of monoplace hyperbaric chambers, is pleased to announce its newest chamber design, the Model 3300E. The 3300E incorporates features which enhance patient comfort, patient safety, provide better operator convenience and lower operational costs. Derived from our Model 3200, the industry “gold standard” since 1995, the 3300E incorporates an Electronic Control Module to control the compression rates and pressure. The ECM allows control of the Pressure Set and the Rate Set in the same manner as the proven Model 3200. In addition, the sophisticated electronics provide: • An Oxygen Conservation System that provides the following benets: Prole then smoothly ramps up the rate to reach the desired Pressure Set. This method allows for maximum patient saturation exposure without exposure to possibly discomforting compression rates. 1. Up to 65% less oxygen consumption per treatment compared to conventional chambers 2. Reduced supply requirements when providing oxygen for multiple chamber installations 3. 95% oxygen level within 10 minutes in the chamber under any operating conditions 4. Greatly reduced noise levels during the pressure plateau. • A Comfort Prole that compresses the chamber at a variable rate that allows more comfortable ear pressure equalization rates. • Other features include; 1. The ability to monitor the internal chamber temperature in Celsius or Fahrenheit. 2. Accurate selection of pressures and rates with a resolution of 0.1 psig. 3. Operator selected pressure values of ATA, psig, kPa or MPa. 4. Built-in up and down timers with audible reminder beeps. 5. Two built-in internal nozzles located on the inside of the chamber door that can direct gas ow to the patient. The Comfort Prole automatically adjusts the compression rate throughout the compression phase of a treatment cycle. It provides a slow compression rate during the rst one-third of the compression phase. This allows the patient to accommodate for initial changes in inner-ear pressure gradually. The Comfort The Oxygen Conservation Mode can signicantly reduce the amount of oxygen consumed during a treatment. A monoplace hyperbaric oxygen treatment that begins under ambient air conditions requires a high purge ow in order to eliminate the presence of nitrogen within the chamber. Once the nitrogen has been purged from the chamber and the internal oxygen concentration has exceeded 95%, high ows are no longer needed to maintain the patient’s saturation level. The Model 3300E automatically switches from an initial high ow purge rate system to a potentially lower plateau purge system. The initial high purge ow cannot be set to less than 300 lpm to assure the nitrogen purge. The plateau purge ow can be set to 80 lpm. Using a lower sustaining purge ow can allow savings of ~65% of the oxygen that would normally be consumed. The lower sustaining ow also provides the benet of lower noise levels for the patient. The Electronic Control Module provides additional unique safety features. In the unlikely event that any of the electronic or pneumatic systems fail, the ECM will automatically create a Safe State environment. This Safe State, announced by audible and visual alarm Indicators, will terminate the treatment and safely decompress the chamber at the purge ow rate in effect at the time of the safe state condition. In addition, the ECM monitors the system for safe operation and will alert the operator to any unusual operating characteristics or system errors.
