AVI 1-Place Smart O2 Valve with 408L Bottle and Altus Meso
The Altus AVI and 408L 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 lighter bottle with a pulsed delivery system that factors pressure altitude, respiration rate, and custom user parameters to extend oxygen duration by more than 4X. This lightweight system offers incredible endurance, which time can be extended more using the Aithre Illyrian oximeter.
Other important features are a built-in wireless Altus pressure gauge, in-app respiration rate and flow rate monitoring, and auto oxygen on/off settings based on measurements of oximetry, heart rate, carbon monoxide, and pressure altitude. Additionally, the emergency mode with higher flow rates equivalent to 12.5 LPM starts automatically when using the app and when your Aithre Illyrian measured oximeter reading drops below 85%, Aithre Shield carbon monoxide levels exceed 50 PPM, or pressure altitude of 18k MSL is reached.
1 PLACE
The AVI includes one quick cannula connect for pilot use. A 100% silicone soft cannula is provided to ensure total comfort without any stiffness - even maintaining supreme flexibility at low temperatures.
SMART PULSE
Our smart pulse system is the first ever to base pulsed oxygen on MEMS flow measurements. This technology provides enhanced inhalation detection plus provides real-time flow rate determinations 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 oxygen and dynamic pulse duration based on respiration rate and pressure altitude. Simply plug in your cannula, plug in power, and oxygen will begin pulsing. The AVI works without the Aithre Connect app, but the savings is less because the AVI operates at the 18k MSL pressure level without the app. By using the Aithre Connect app, the AVI automatically titrates the oxygen delivery amount based on pressure altitude and provides for further user customization and emergency overrides. Further, with the Aithre Illyrian oximeter, the app allows the pilot to scale down the total oxygen delivery amount to squeeze every drop of useful oxygen out of the system without compromising safety.
MICRO BURST TECHNOLOGY
The AVI delivers each pulse of oxygen as a series of micro bursts with each inhalation. The micro bursts start immediately upon inhalation and extend over the the first critical portion of the inhalation cycle. The number and spacing of the microbursts are adjusted in real-time and customized for each inhalation based on respiration length, pressure altitude, and other factors. The benefits of microbursts over a single pulse is that the oxygen is infused over the course of inhalation making the delivery smoother and more efficient.
IN-APP RESPIRATION MONITORING
Respiration rate and flow information are updated about every 12 seconds in the Aithre Connect 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. And, the AVI can detect when a cannula has been disconnected or kinked because of the absence of respiration. The app will alert you of the start and stop of oxygen and, when no respiration is detected, the AVI will emit a periodic buzzer sound.
AUTO MODE SETTINGS
The iOS auto mode settings of the Aithre Connect app 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, but oxygen will always occur over 10k MSL while in auto mode. The heart rate is interesting because oxygen use is demonstrated to reduce your heart rate and we are observing the ability to impose resistance to heart rate surges during stressful parts of flight. The oxygen during carbon monoxide exposure will not prevent carbon monoxide poisoning, but may improve your odds of being able to remedy an exposure problem.
USER SELECTION OF PERCENTAGE OF STANDARD
The Aithre Connect app provides the ability for adjustment of the oxygen concentration of oxygen. We have developed an algorithm that is based on the 1 LPM per 10K MSL that is used by the FAA. However, in some cases this amount is not sufficient for a user and more is desired to maintain a high SPO2 percentage. In other cases, this amount is too much and less oxygen concentration may be desired. Within the app, a slider bar is provided for the pilot that can be dragged to higher or lower percentages of standard. You can always increase the percentage of standard, but for safety you cannot decrease the percentage of standard below 100% without also wearing the Aithre Illyrian oximeter for continuous SPO2 readouts to your phone and paired headset.
ALTUS WIRELESS PRESSURE GAUGE
The regulator includes 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 10 PSI to permit monitoring of your oxygen bottle pressure. The PSI can be displayed on your Garmin G3x or Dynon Skyview when using the companion Aithre Shield EX 3.0 carbon monoxide detector.
AITHRE ILLYRIAN AND AITHRE SHIELD COMPATIBLE
The AVI works in conjunction with the Illyrian continuous flow oximeter and the Shield carbon monoxide detectors when used with the Aithre Connect app. The app receives the information and provides a health dashboard with consolidated output of associated parameters for health and oxygen. Additionally, the app uses the information received from other Aithre devices to control the AVI, such as to put the oxygen system into emergency mode to provide enhanced safety. As with the Meso pressure gauge, the Illyrian oximeter and Shield carbon monoxide data can be output to your Garmin G3x or Dynon Skyview when using the Shield EX 3.0.
12V POWER WITH 5V STEP-UP OPTION
The AVI smart valve is a 12V device that uses max current of 250 mA. It can be wired to 12V ship power for experimental aircraft 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 convert the 5V USB to 12V power for the AVI.
REGULATOR
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. There are two output ports on the regulator. The first output port is a quick connect port which connects to the AVI and provides always-on full flow oxygen to the AVI for pulsed output. The second output port is a backup port directly available to a cannula and usable independent of the AVI for adjustable continuous oxygen flow.
CARBON FIBER COMPOSITE BOTTLE WITH ALUMINUM LINING
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 4 lbs (most of the weight is attributed to the regulator itself). The bottle features a high-gloss finish and unique grey color that pops.
EASY INSTALLATION
The AVI is strapped to the bottle with the provided VELCRO strap. From there, the AVI accepts the 6mm plumbing line from the regulator and provides the output flow via the cannula quick release plugs. The AVI will pass oxygen to the cannulas when the power is on and inhalation is detected.
