Environmental Tectonics Corporation Announces Additional Baramed Monoplace Hyperbaric Chamber Sales

Southampton, PA, February 23, 2010 - Environmental Tectonics Corporation's (OTC Bulletin Board: ETCC) ("ETC" or the "Company") Biomedical Systems Division today announced the placement of two (2) BARA-MED XD computerized monoplace hyperbaric oxygen chambers at Blue Mountain Health System Hyperbaric and Wound Care Center, Lehighton, PA.

Hyperbaric chambers are used in Hyperbaric Oxygen Therapy (HBOT), which is a non-invasive procedure where the patient breathes 100% oxygen while fully enclosed in a specially designed chamber at increased pressure. HBOT is the primary treatment for carbon monoxide poisoning, arterial gas embolism and decompression sickness. It is also used to promote and support healing in the management of conditions in which oxygen transport to the tissues has been disrupted by traumatic injury, infection, inflammation, or edema.

All of ETC's monoplace hyperbaric chambers contain a fourth generation, automated control system called O.S.C.A.R. ™, (Operating System for Control And Recordkeeping). Among its many features, O.S.C.A.R. ™ includes a patient friendly pressure-change technology known as SMOOTH-RIDE™. SMOOTH-RIDE™ reduces the risk of complications due to middle ear and sinus barotraumas during compression. During decompression, SMOOTH-RIDE™ reduces the risk of air trapping in cases of potential obstructive or restrictive pulmonary conditions, such as chronic obstructive pulmonary disease (COPD), asthma, and emphysema. SMOOTH-RIDE™ achieves these important risk reductions without having to increase the times of the pressure changes.

Tammy L. George, RN, BSN, Program Director for, The Blue Mountain Health System Hyperbaric and Wound Care Center, stated "We chose to go with the ETC chambers for many reasons. The most important reason was the chambers provide computerized treatment protocols with accurate dive documentation and easy-to-use litters which can be adjusted for effortless patient loading and unloading. The ETC hyperbaric chambers also provide more than ample room for patients to shift or change positions easily. Our patients are more than pleased with the chambers, which results in a better compliance ratio. Blue Mountain Health System Hyperbaric and Wound Care Center uses these hyperbaric chambers for a variety of patient issues, such as to help heal diabetic wounds and treat Osteoradionecrosis (both pre- and post-tooth extraction) as well as other Medicare covered conditions."

Bob Salmons, NE Regional Sales Manager, commented that, "Customers are purchasing ETC chambers because they demand both the quality and technology that only ETC provides."






ETC designs, develops, installs and maintains aircrew training systems (aeromedical, tactical combat and general), disaster management training systems and services, entertainment products, sterilizers (steam and gas), environmental testing products, hyperbaric chambers and related products for domestic and international customers.
