Reduced Oxygen Breathing Device 2 (ROBD2) Licensed from U.S. Navy under U.S. Patent Application No. 10/959.764 DESCRIPTION The Environics® Model 6202, Reduced Oxygen Breathing Device 2 (ROBD2), is a portable computerized gas-blending instrument used to produce hypoxia without changes in atmospheric pressure. This simulated altitude exposure can be utilized for both research and training purposes. The U. S. Navy currently uses the ROBD2 to train aircrew to recognize the signs and symptoms of hypoxia and to perform the appropriate emergency procedures and additionally, conducts hypoxia research. The ROBD2 uses Thermal Mass Flow Controllers (MFC) to mix breathing air and nitrogen to produce the sea level equivalent atmospheric oxygen contents for altitudes up to 40,000 feet. The MFC’s are calibrated on a primary flow standard traceable to the National Institute of Standards and Technology (NIST). The ROBD2 introduces pressure changes and gas expansion as a function of altitude. The software is menu driven. The main operators menu consists of three selections, simplifying the use of the system for the field operator. Built-in self-tests verify all system component functionality before the operation of the system can begin. If any self-test fails the system will not operate. The system is designed to work with both bottled gases and gases produced by a Nitrogen/air generator. SAFETY FEATURES • Prevention of over pressurization of the subject's mask • Prevention of reduced oxygen contents below those being requested for a particular altitude • An emergency dump switch that will supply 100% O2 to subjects. • Built-in self-tests verify all system component functionality before the operation of the system can begin. KEY FEATURES • 0-40,000 feet elevation • Integrated pulse oximeter with finger probe • Integrated oxygen analyzer • Emergency Oxygen dump switch for delivery of 100% oxygen • A new pulse oximeter with touch screen interface • Enter one flow rate for all altitudes between 40 and 80 LPM • Breathing bag is replaced with an internal reservoir, generating a faster refresh rate to the mask. • Addition of an inline Oxygen particle filter. • Pulse ox probe connection moved to the rear of the chassis • HRT is the only program type. APPLICATIONS • Aircrew training and research • High altitude training and research • Medical stress testing • Hypox
