GO2Altitude® Hypoxicator system Gas cylinder based industrial gas mixer Normobaric Hypoxia chamber
Training efficiency, practicality, ease of use
Easy to integrate with any flight simulator. GO2Altitude hypoxicator software easy to integrate with practically any type of Flight Simulator software: from MS FlightSim up to a Full Motion simulator of any aircraft. Impossible to fit into a modern flight simulator due to the physical over-size and bulky gas-cylinder plus operator required to manually operate the mixer The simulator needs to be built-into a chamber with a long list of associated issues eliminating all the advantages of normobaric hypoxia training
Compact, ergonomic, fully automated and computerized, purposely designed training system.
Normobaric hypoxia is provided by on-site hypoxic \ hyperoxic air generator using medical grade semipermeable membrane air-separation technology (similar to one used in aircraft’s oxygen generators)
Gas bottles of nitrogen, oxygen and compressed air required to operate this system. The gases are mixed by an industrial gas mixer to a desired O2 concentration. The rest of the training is upto the operator that controls the order of simulation altitude, interrogates trainees on their individual symptoms, asks to perform cognitive tasks (pen and paper) or flight a Msoft flight simulator. Copy of the 1950-s hypobaric chamber without the effects of hypobaria. Single simulated altitude. Accumulation of CO2 and humidity inside of the chamber somewhat affects the accuracy of simulation.
One instructor simultaneously observe 2-3 trainees, session is lead by GO2altitude system training software in “automatic” mode “One-to-one” training. One ACLS accredited instructor – one trainee Same as hypobaric chamber “mask-off” training methodology
Simulated flight altitude steps is set-up in the training profile for the particular group of trainees (e.g. NAVY PILOT, AIRFORSE PILOT, CABIN CREW, GA etc). The system is then automatically changes altitudes during the practical training and supply oxygen for recovery automatically when required. Sufficient number of E-size gas cylinders should be constantly kept in stock, to replace quickly emptying bottles.
During practical training operator must interchange hoses to supply oxygen for recovery. Simulated flight profile timing is manually controlled by a timer or a stopwatch.
Single fixed simulated altitude. Mimic of the old hypobaric chamber training procedure without the feel of hypobaria. Simulated altitude can not be rapidly changed because it takes hours to achieve new simulated altitude (fill in the chamber with different FiO2 gas)
SpO2, Hear Rate, Ventilatory frequency are constantly monitored, recorder and presented in training session report. These data are also readily available for scientific research. SpO2 is observed by the training instructor and it is their responsibility to make a decision when to stop the practical session. Pen and paper recording of the important physiological data such as SpO2 and the Heart Rate. SpO2 read and interpreted by the subject using portable finger clip SpO2 sensor. No physiological data is recorded.
To report symptoms, subject selects from a list experienced ones, using touch screen. These reported symptoms are then converted in an automatic printed report that trainee is given to keep. Symptoms are reported by the subject verbally and are no\t recorded for a future review(s). Symptoms reported by subject verbally
Safety aspects
Intrinsically safe design of the system reduces the risk associated with the use of hypoxicator down to the practicality achievable level. Complies with the requirements of international standard IEC60601 Subject’s well-being is in hands of external observer / operator. Cognition assessed by observer . Creates Incompatible with life and inescapable environment. Complete reliance on the operator(s) to rescue the trainee if the need be.
Automatic safety cut-off mechanism aborts training and oxygen for recovery is supplied via the same mask. No automatic safety cut-off mechanism. Full reliance on the operator to supply hyperoxic air for recovery. No automatic safety cut-off mechanisms. Full reliance on the operator to supply hyperoxic air for recovery.
Educational impact on the trainee
Pencil & paper cognitive testing Pencil & paper cognitive testing
Deterioration of cognitive function is demonstrated to the subject objectively via printed reports of the graphs showing detrimental effect of hypoxia on accuracy of responses and increased time to respond. Deterioration of cognitive function is demonstrated to the subject objectively using old style ‘pen-and-paper” battery of cognitive test OR by discussing individual hypoxia symptoms over a “radio” External observation of psychomotor tests by observer.
