Text of the page (random words):
openaps loopers are kids who have parents who have chosen to build closed loops for their families how many people are using openaps check out the outcomes page to see the general count of number of people worldwide we estimate may be using diy closed loop systems is it a pid controller is it an mpc does it use fuzzy logic or ml machine learning the oref0 algorithm is a heuristic based algorithm meaning it s designed to follow the same math a person with diabetes themselves uses to make decisions about insulin adjustments some of the more complex controllers can become black boxes to the user obfuscating the rationale behind its decisions not only can this be dangerous with an experimental system but it can also lead to frustration even when the system is doing the best thing possible read more about the design of the openaps algorithms in the reference design which is designed for the user to be able to understand all the decisions the system is making and check out this page in the openaps documentation that explains how decisions are made by the algorithm can i buy an openaps no where how do i get an openaps openaps is not an fda approved system or device it s not manufactured or sold anywhere in the world it s an open source designed system that you can choose to build yourself what do i need to build an openaps implementation for the most up to date hardware list check out the hardware page in the openaps documentation in general you need a compatible insulin pump a continuous glucose monitor and a computer with a radio to communicate bi directionally with the pump this is specific to an openaps implementation openaps does not require a phone you may also want to check out the androidaps documentation for an android phone based implementation of the openaps algorithm and interoperability with additional insulin pumps and although it doesn t use the same algorithm safety design or feature set as openaps and androidaps you can also check out the loop documentation for another open source system option that requires an ios device where is the code for openaps where is the documentation for openaps the code is available open source on github so is the openaps documentation tip start by looking at the documentation if you re wondering how to get started do i have to know programming or be technical to build an openaps no but you do have to be willing to learn a few new to you things there are resources to help you figure it out including step by step comprehensive documentation the diy part of openaps is important because there s no customer service if it breaks or stops working you ll have to fix it yourself so the building process is valuable because you ll be well equipped to figure out what might have stopped working and why once you have a working closed loop implementation will my pump work with openaps right now the only pumps that work with the openaps safety focused reference design are older versions of medtronic pumps find more details about which versions of the pumps are compatible in the hardware section of the openaps documentation you may also want to review the androidaps or loop which doesn t use the openaps algorithm feature set or safety design documentation for information on what pumps those systems currently have interoperability with will my cgm work with openaps most cgms work with openaps including dexcom g4 including with share dexcom g5 dexcom g6 medtronic cgms and other commercially available cgms could openaps damage my pump or shorten its lifespan we currently have years of cumulative openaps pump operations and our collective experience indicates that using a diy closed loop will not damage your insulin pump we do not have any reports of pumps becoming disabled locking up or being bricked by frequent radio communications however all users report an increase in battery usage so you ll change the aaa battery more often we have several members in the community who have been using the same pump with their diy closed loops for 3 4 years without issue could someone hack my insulin pump or control my insulin delivery this may be true even if you don t use a diy closed loop we believe that every potential openaps user needs to weigh the risks associated with using openaps versus the risks of not using the system any time a device uses radio communications there is some risk that the device could be exploited and this is true from standard non looping pump operation as well currently we are not aware of anyone attempting to harm individuals by hacking their diabetes related medical equipment however there are multiple ways openaps users can mitigate such risks even if they are unlikely first in the pump settings limit both the max bolus allowed and max temporary basal settings to amounts that you believe are safest these are hard limits that we do not believe any malicious hacker could circumvent second leave your cgm alarms enabled for both highs and lows third monitor your insulin delivery online nightscout users can set additional alarms to alert for a wide variety of conditions including conditions that are much more likely to occur than a malicious attack in addition to highs and lows nightscout can display many different data points useful for verifying that the pump is operating as desired including your current iob pump temporary basal history pump boluses history it can also be configured to proactively alert users to undesirable conditions such as predicted highs and lows low insulin reservoir and low pump battery in the event a malicious attack was made on your insulin pump the above strategies would significantly mitigate the risk posed by such an attack it is also worth noting that the openaps community is continuously working to improve the safety and security of their systems does it work with an iphone or android based phone make sure to read the above questions or the documentation about what equipment you need for a standard openaps implementation you can view your data on any phone iphone or android or computing device most openaps implementations require additional hardware like an intel edison in order to run the closed loop system since it is not a phone based system openaps does not require a phone and you can use openaps regardless of whether you have an iphone or android phone how much does openaps cost to build it depends on how much equipment you already have the hardware components usually cost around 150 usd some people are able to buy second hand rigs or parts or find them being given away for free within the community but many people also need to find a compatible pump which ranges from free ask a friend or around your local community to several hundreds of dollars also be warned most people end up building a second rig hardware setup or more so they can have a mobile rig and an at home rig etc why would someone build an openaps individuals who build openaps setups have decided that wearenotwaiting to be able to automatically adjust basal rates to safely keep bgs in range and reduce the burden of living with type 1 diabetes for context the first diy closed loop that was the inspiration for openaps was completed in december 2014 back when the forecast for commercial closed loop systems was still 3 4 years away what does the fda think about openaps you can google it or ask them yourselves our take on what they ve told us directly as well as what they ve said publicly their responsibility is to regulate products on the commercial market and help safeguard the public openaps is not a commercial product and is not sold or distributed in anyway individuals who build an openaps are essentially doing an n 1 experiment which they have a right to do to by themselves that is not a regulated activity by the fda what do you think of bigfoot beta bionics ilet bionic pancreas medtronic typezero tandem cellnovo animas insulet diabeloop roche cambridge s efforts to close the loop and create an artificial pancreas we support all of the companies working to commercialize a closed loop system we just wish they would each get their solution s to market more quickly this is part of what we re working to do as a community we are working to demonstrate the need of the community to have closed loop systems demonstrate the safety of basic closed loop systems and efficacy compared to standard of care without closed loops and help break down communication barriers between the fda these companies and the community that needs the devices widely available as quickly as possible and in the meantime many of us are not waiting wearenotwaiting by building and running our own diy openaps implementations who is behind openaps there is an amazing community of people behind openaps dana lewis and scott leibrand built the first diy closed loop system called diyps that was the inspiration for the open source version of a closed loop system now known as openaps they spend a lot of time supporting the community in various ways including continuing development on many of their algorithms that are now used by the community one of the other founders behind the openaps movement is ben west who identified the way to communicate with medtronic pumps in addition to other open source work he does with diabetes devices dana and scott worked with ben as he built the openaps toolkit which became the building blocks of the first openaps implementation many other people have also contributed to the community in various ways from writing documentation building unit tests testing new features and algorithms incorporating openaps data with visualization tools like nightscout and making the data easily viewable on pebble watches building new software to communicate with pumps etc you ll find a lot of people from the community sharing their experiences using their openaps implementations and documenting new tools in progress via the openaps hashtag on twitter where is openaps located openaps is not an organization and thus does not have a traditional location openaps is an open source project however when publishing the affiliation of openaps can be used with the location of seattle wa us which is where the open source project began i m interested in learning more but i m not quite ready to close the loop for myself what else can i read for a bigger picture look at automated insulin delivery technology you can read artificialpancreasbook com this has information about closed loop technology for every day usage tips for helping to determine whether this type of technology either diy or commercial is right for you information for healthcare providers a summary of the latest aps research and more i have more questions who can i talk to hmm you really have a question we haven t answered above ok here s where to go questions about equipment required to build openaps questions about the design of openaps questions as you work through building your own openaps implementation if you couldn t find your answer in any of the above places channels email dana openaps org and or scott openaps org in the news
