The Altus AVI8 and 152L Aithre carbon fiber bottle is the first smart oxygen system that is integrated with your iOS device and the Aithre suite of health technology products to deliver smart pulsed oxygen.  You get a smaller, lighter bottle with an pulsed delivery system that factors pressure altitude, respiration rate, and real-time optical flow measurements to extend oxygen duration by 7X.  This handheld-sized system offers incredible duration.  At 6 lbs total weight and 2000 PSI, we are demonstrating 0.36CF or 10.2L of consumption per hour at 15k MSL with blood O2 saturation continuously above 95% - making the 152L bottle outperform even the largest traditional aviation oxygen tanks at 12 hours of use time.

Other important features are a push button remote on/off button, wireless Altus pressure gauge, in-app respiration rate and flow rate monitoring, and auto mode settings based on measurements of oximetry, heart rate, carbon monoxide, and pressure altitude.  


The AVI8 includes two quick cannula connects for either pilot or copilot use.  Each place includes an independent smart pulse circuit and highly sensitive optical flow meter.  Two of the softest cannulas you've ever used are provided and ensure the total comfort of you and your passenger without any stiffness ever - even maintaining supreme flexibility at low temperatures.


Our smart pulse system is the first ever to base pulsed oxygen on optical flow measurements.  This technology provides enhanced inhalation detection plus provides real-time flow rate measurements and accurate respiration rate feedback.  What makes the system smart is the integration with the Aithre Connect iOS/WatchOS app with in-app control of pulse state and dynamic pulse duration based on respiration rate, pressure altitude, and oxygen flow rate.  Simply set your oxygen system to 2 LPM per person and the smart pulse will take care of the delivery quantity with near instant adjustments as you climb and change your breathing rate.  Because we integrate the Illyrian oximeter continuous pulse oximetry, the app allows the pilot to titrate down the total oxygen delivery amount to further squeeze every drop of useful oxygen out of the system without compromising safety.  


The Aithre AVI8 includes a custom O2 handle button with a 3 foot cable to permit turning the oxygen flow on and off when the oxygen located in the seat back location.  When the O2 button is pushed, the AVI8 comes to life and delivers oxygen.  Oxygen can be discontinued at anytime by pushing the O2 button again to the off position.  The oxygen can be safely turned off and left off without physically adjusting the regulator flow meter, with long periods between use and without measurable leakage.  


Respiration rate and flow meter information is updated about every 12 seconds in the app, providing near-real-time snapshots of your breathing rate and the volume of oxygen being delivered.  This additional information improves and replaces the physical inline flow meter that has traditionally been part of oxygen systems.  The flow rate can be adjusted both on the built-in flow meter of the regulator as well as the fine adjustment knob of the AVI8.  


The iOS auto mode settings are options that permit you to define when the oxygen should begin and end.  There are four options currently: pressure altitude, heart rate, SPO2, and carbon monoxide.  Each option has a slider bar that allows you to set when the oxygen should start and then a touchable switch that enables or disables the setting.  Any or all of the parameters can be defined so that whenever one of the variables is triggered, the oxygen will start automatically.  For instance, pressure altitude can be set to 10k, SPO2 can be set to 92%, carbon monoxide can be set to 5 PPM, and heart rate can be defined as 100 bpm.  If any of these parameters occur, then the oxygen will turn on.  Conversely, if none of the parameters are met then the oxygen is off.  The heart rate is interesting because oxygen use is demonstrated to reduce your heart rate and we are observing the ability to cap your heart rate surges during stressful parts of flight.  The oxygen during carbon monoxide can also minimize the amount of carbon monoxide exposure - not prevent, but improve your odds of being able to remedy an exposure problem.  


The regulator includes the standard pressure gauge, and also the Aithre Altus Meso wireless tank pressure gauge preinstalled for use with the Aithre Connect app.  This provides 0-2500 PSI readings to your iOS device in increments of 10PSI to permit monitoring of your oxygen tank without having it right next to you.  The PSI can be displayed on your Garmin G3x or Dynon Skyview when using the companion Aithre Shield EX 3.0 carbon monoxide detector.  


The AVI8 smart valve is a 12V device that uses max current of 500mA.  It can be wired to 12V ship power and includes an onboard fuse with over current and reverse current protection.  Alternatively, provided is a 5V USB cord with a built-in step up circuit to covert the 5V USB to 12V power for the AVI8.  


The Aithre adjustable flow regulator is a unique combined regulator-valve with dual ports, an integrated flow regulator, and built-in fill valve. The regulator includes a standard CGA-540 fill port, but it is one-way and doesn't require removal of any parts to fill.  An elegant metal handle shroud provides protection against dropping.  There are two output ports on the handle.  The first output port is a quick connect port which connects to the AVI8 and provides 0-25LPM built-in regulation, with additional fine-adjustment of flow on the AVI8 itself.  The second output port is a backup quick connect for directly connecting an independent flow meter type cannula (separate flow meter not included sold separately). 


The Aithre carbon fiber bottle comes with CE certification to ISO 11119-3 safety standards.  It is extremely lightweight with the combined bottle and regulator weighing just over 4lbs (most of the weight is attributed to the regulator itself).  Plus, we added the Aithre touch with a high gloss finish and unique light grey/dark grey fiber and resin color that pops.  


The AVI8 is strapped to the bottle with the provided rubber mount and VELCRO strap.  From there, the AVI8 accepts the 6mm plumbing line from the regulator and provides the output flow via the cannula quick release plugs.  The AVI8 will pass oxygen to the cannulas when the button is pushed or the iOS app can be used to set automatic parameters for heart rate, blood oxygen, altitude, and carbon monoxide, and activate the smart pulse mode. 


The AVI8 can be mounted up to 15 feet from the cannulas.  There is no requirement to keep the AVI8 on or near your person and the smart pulse operation is unaffected by distance.  For experimental aircraft, we offer an optional plumbing kit and bulkhead fitting set to permit baggage compartment mounting of the AVI8 and bottle, with behind-the-panel plumbing to each station.
