An MIT team created a ventilator that only costs $100 using a common hospital item

One of the biggest obstacles to treating patients with COVID-19 is the worldwide ventilator shortage. New York state is the hardest-hit region in the U.S. and the situation is so dire, Governor Andrew Cuomo recently put out a call for 30,000 additional ventilator units.

A study from Imperial College in London found that an estimated 30% of all people hospitalized due to the virus will need a ventilator.


COVID-19 creates inflammation and fluid build-up in the lungs, which makes it very difficult for people to breathe — especially those with chronic respiratory problems. For these patients, a functioning ventilator can mean the difference between life or death.

One of the major obstacles to ventilator production is the cost. A ventilator can cost hospitals up to $30,000.

A team at MIT has been working day and night to create an emergency ventilator that costs only $100 to produce. The ventilator uses a bag-valve resuscitator, a common hospital item.

A bag-valve resuscitator or Ambu bag, is a self-inflating, hand-operated resuscitator used by first-responders to temporarily help people having difficulty breathing before they are able to hook them up to a ventilator.

They're affordable, costing about $20.

The MIT engineers created a mechanism that squeezes and releases the bag without needing a human operator. The big issue is that the ventilator has to be extremely reliable because any mechanical failure would surely result in death.

"The primary consideration is patient safety," one team member told SciTechDaily. "So we had to establish what we're calling minimum clinical functional requirements." The team members wish to remain anonymous to prevent any unnecessary attention that would delay their work.

The ventilator must also be adjustable to pump the correct amount of air given the patient's lung capacity.

The ventilator project didn't start from scratch. It was informed by a project done a decade ago by MIT students in a Medical Device Design class. The students published a paper outlining their design and testing, but the work stopped there.

The new team used their research as a jumping off point to make their ventilator.

In just over a week, the team has gone from empty benches to a working prototype. Its prime motivator has been reports of doctors being forced to ration ventilators.

"We all work together, and ultimately the goal is to help people, because people's lives understandably hang in the balance," one team member says.

The engineers are currently looking to have the ventilator approved by the FDA.

"The Department of Health and Human Services released a notice stating that all medical interventions related to Covid-19 are no longer subject to liability, but that does not change our burden of care." he said. "At present, we are awaiting FDA feedback" about the project. "Ultimately, our intent is to seek FDA approval. That process takes time, however."

Ultimately, the team hopes to publish the plans for the device online so that other engineers can improve on their designs and to make the device available to hospitals across the globe.

Innovation is awesome, right? I mean, it gave us the internet!

However, there is always a price to pay for modernization, and in this case, it’s in the form of digital eye strain, a group of vision problems that can pop up after as little as two hours of looking at a screen. Some of the symptoms are tired and/or dry eyes, headaches, blurred vision, and neck and shoulder pain1. Ouch!

Artist Haley Morris-Cafiero describes herself on her website as "part performer, part artist, part provocateur, part spectator." Her recent project, titled "Wait Watchers" has elements of all her self-descriptors.

In an email to us, Morris-Cafiero explained that she set up a camera in the street and stood in front of it, doing mundane activities like looking at a map or eating gelato. While she's standing there she sets off her camera, taking hundreds of photos.

Three McDonald's workers help deliver customer's baby

Usually when someone walks into McDonald's they expect to walk out with something to eat, not a baby.

But for new mom Alandria Worthy, that's exactly what happened. Worthy was on her way to the hospital but needed to use the bathroom so she had her fiancé make a pit stop at McDonald's.

After a few minutes of Worthy being in the bathroom, workers heard the mom to be screaming which prompted Tunisia Woodward, the manager on duty to check things out. The her surprise, she was about to turn into a labor and delivery nurse.

Woodward explained in an interview with 11 Alive that she saw feet under the stall door before saying, “I opened, and she was on this toilet lying back, screaming. Then I knew to tell my crew, ‘We’re having a baby today.’” Woodward was right, the baby was coming and the three moms are duty were there to help.

Failure is a great teacher.

It’s true that life never gets easier, and we only get continuously better at our lives. Childhood’s lessons are simple—this is how you color in the lines, 2 + 2 = 4, brush your teeth twice a day, etc. As we get older, lessons keep coming, and though they might still remain simple in their message, truly understanding them can be difficult. Often we learn the hard way.

The good news is, the “hard way” is indeed a great teacher. Learning the hard way often involves struggle, mistakes and failure. While these feelings are undeniably uncomfortable, being patient and persistent enough to move through them often leaves us not only wiser in having gained the lesson, but more confident, assured and emotionally resilient. If that’s not growth, I don’t know what is.

Co-op CEO Shirine Khoury-Haq.

The CEO of Co-op, one of the UK’s largest supermarket chains has made an important statement about excess at a time when many families are struggling in the UK.

The Daily Mail reports that Shirine Khoury-Haq, the head of a company with over 3900 retail locations says she’s giving her twin, six-year-old daughters one present each this Christmas because she could not “in good conscience” give them more while millions of families struggle with inflation and high energy prices.

Khoury-Haq makes over £1 million ($1,190,000) a year after bonuses, so she pledged to give her family's present money to those in need. “It just feels like excess, given what’s happening in the world. In good conscience, I can’t do that in my own home,” Khoury-Haq said according to The Guardian.

“The rest of our budget will be given to Santa to provide presents for children whose parents can’t contribute to the elves,” she continued. “We’re going to go out shopping for those other presents and [we will] send them to Santa.”
