The low-cost,
build-it-anywhere ventilator

Combating a propagating virus with a scalable breathing machine

An enemy of global proportions

  • There’s 20,356,053 people, for every ventilator in DR Congo.

  • As of April 17, Somalia had zero working ventilators.

  • Venezuela has 84 ICU beds for a population of 32 million.

  • 41 African nations share a total of 2,000 working ventilators.


20 Masters

We’re building model ventilators for regulatory approval in 20 countries. Each will serve as the template for local reproduction.

Endless Copies

Engineered with off-the-shelf parts to bypass typical supply chains. So governments and orgs can mass-produce devices on-site, and en masse.

Contagious Hope

We’re helping the production of ventilators keep up with the global rate of infection, whenever and wherever it spikes.

How it Works

AmboVent uses an adjustable mechanical arm to pump a resuscitator (or Ambu) bag directly to the patient’s lungs.

Ambu (or self-inflating bag), is a common medical device found in hospitals all around the globe.

AmboVent uses a robot-controlled arm to inflate the bag with precise amounts and at constant rates.

Operators use dials to control breathing speed, inhalation pressure and tida (air) volume, with exact precision.

It’s built with off-the-shelf components like snowblower motors, Arduino boards, and common pressure sensors.

Uses a framework that can be rapidly manufactured using CNC and 3D printing techniques.

Includes safety features like battery backup and shut-off that automatically restarts the breathing cycle if too much pressure is detected.

Some of the organizations integral to the success of AmboVent
in the fight against the Covid-19.


What is AmboVent?

AmboVent is a new low-cost, open-source breathing machine that can be reproduced anywhere. It uses a common Ambu bag powered by an algorithm and robotic arm to reproduce a ventilator. It controls respiratory rate, volume and compression, generating a simple but effective alternative for a $10,000 ventilator. Once it reaches local mass-production it can be manufactured for an estimated cost of 500 to 700 dollars per unit. You can read more about it here on Wikipedia

Who will be Using AmboVent?

AmboVent will be used by trained medical teams in hospitals all over the world. As part of their medical protocol to support anesthetized and ventilated Covid-19 patients, as well as other anesthetized patients.

Is AmboVent the most affordable ventilator in the world?

Probably. In a recent comparison it received some of the highest marks across openness and buildability.

Can AmboVent really save lives?

Medical teams all around the world have used the Ambu bag to save lives for decades. This is the basic medical device our AmboVent robotic arm uses to send air to the patient’s lungs. For now, the AmboVent has only saved only the lives of anesthetized animals ventilated during medical testing. It remains a last resort type of device, only to be used when no other alternative exists. But in underserved communities across Africa, South East Asia and South America, AmboVent will likely be the only option available.

Does AmboVent help COVID-19 Patients?

Yes. In two different ways: In well-equipped hospitals AmboVent will take the place of high-end machines for non-corona patients. In underserved hospitals in more remote areas of the world, AmboVent will likely be the only breathing machine available to COVID-19 patients.

Is AmboVent approved as a medical device?

The bag valve mask (or Ambu bag), is an approved medical device used by medical professionals all over the world. This self-inflating bag is the key component of our device—the machine acts as the regulator for the bag, controlling respiration rate, volume and pressure. The combination of our device and Ambu bag is not yet approved. It’s been submitted to the Israeli health authority. It’s on a fast track for Covid-19 related innovation. Approval is expected in a matter of weeks.

Has the machine been clinically tested?

The device is going under strict tests required by the Israeli health authorities. It scored high when tested on animals at the Hadassah medical center in Jerusalem. An application for the Helsinki protocol approval was submitted in order to test the device on humans next. It’s also undergone laboratory trials at Hadassah and Ichilov Medical Center and has been rated as a leading solution among dozens of open-source ventilator projects by volunteers at Public Invention and

Who is behind the AmboVent initiative?, a non-profit composed of 60 Israeli entrepreneurs, engineers, physicians, medical and educational organizations, and led by Dr. David Alkaher. It was developed in just under 10 days, and released its code, designs, and specs free to the world on GitHub. Read more about the founders and the initiative here. (Bloomberg)

Is AmboVent a business?

AmboVent is not a business. It is a not-for-profit initiative, and it's officially registered as a nonprofit organization in Israel.

Can AmboVent be used at home?

No. It's use is restricted to hospitals under the supervision of medical professionals.

Is AmboVent safe to use for kids?

Not for now. COVID-19 affects adults and the elderly but almost no children. So this version of the AmboVent prioritizes those who are most at risk. With more donations, we’re hoping we can focus on respiratory needs of children in the future.

When will AmboVent be available worldwide?

Some 300 teams are already prototyping the device around the world. In DIY workshops, maker spaces and medical basements. But In order to manufacture the device at scale, we need to build master devices that can be accurately replicated by manufacturing partners all over the globe. This fundraising campaign is raising $100,000 to develop 20 of those masters.

How will my money be used?

Your donation will go directly to building each of the 20 master machines, paying for the components that will then be reproduced by the thousands. Making the impact of your donation truly exponential.

$25 - sensors, traffic controllers
$50 - backup battery
$150 - electrical system
$250 - smart card, lung monitoring system
$500 - device engine
$775 - robotic arm, bag valve mask (Ambu bag)
$1200 - system hardware and wiring

Your funds will also go towards the man-power needed to clear medical and regulatory hurdles: hiring the expertise of healthcare professionals, lawyers and authorities on the ground.

Is my donation tax-deductible?

Yes. Donors in the U.S. can get a 501c3 receipt and a 46A in Israel.
Updates on Europe coming soon.

How can I help the AmboVent initiative?

Please email Dr. Eitan Eliram (head of global partnership at with suggestions, feedback or connections to organizations who can help fast-track the approval and production of this breathing machine. You can also make a donation, so we can bring this device to thousands of people and multiply its effect. Finally, we’re one of many in the fight for low-cost ventilators. Join us in supporting and
