This ventilator may not look like an important piece of medical equipment but it may be one of the critical things keeping Covid-19 patients alive. MIT has designed an emergency ventilator that uses commonly found and easily sourced materials. FDA-approved ventilators are expensive and require hundreds of components, and in these trying times a cheaper alternative may be able to save lives as these machines become more scarce.

    So like 3 months too late and wont ne used because … well there are several videos of doctors explaining why.

    Could they build the control box like an app then every part of it could be affordable and easily accessible all you’ll need is a laptop or smartphone

    A bit late? And when it already has been shown that treatment with ventilators is for the most part deadly.

    Because the media kept screaming for ventilators we now have a massive excess of them. So much so that we can afford to export them to other places. We won’t be needing these.

    I thought ventalators success rate was only 20% for covid.

      Survival is like 10-12% and that’s using proper ventilators that don’t ram air into someone’s lungs unlike the ones in this video.

    Ventilators aren’t good (unless you can’t on your own) putting someone prematurely can cause their death

      Yeah my friend’s aunt has covid and pneumonia and her lungs were struggling so they put her on a ventilator and she was dead 3 days later. They are not good for you.

    No one has died because they have not had access to a ventilator

      Well at least in the US and Canada. Cant say I know in the less advanced places. Also not saying it can’t.

    I can tell if this is being touted a machine going to be used to replace respirators or the squeeze bottle. Which is it.

    Non of these people interviewed are described as medical professionals. Where medical professionals consulted?

    • Nicco Saur

      No they were not

    the trick is successfully getting patients off of the ventilators. for that you need a sophisticated machine not just a rudimentary pump…

    ventilators are killing people with covid19, much like aspirin did during the Spanish Flu.

    Wired didn’t consult a actual doctor, I would say this is poorly researched

    I mean on top of this you might want a different air mixture than just bottled oxygen or the surrounding air. Not to mention you might want to sedate your patient, which you would need a pretty skilled doctor for whatever remote location this would be deployed at.

    Or they could just use real ventilators, because who could have guessed it, there is a massive surplus of them because this virus is a scam.

Flock Safety sits at the intersection of an increasingly intense debate around the spread of surviellance technology, AI, and who’s using all of that information and to what ends. Founder and CEO Garrett Langley spoke at TechCrunch Disrupt 2026 to defend his stance that Flock is a net positive in the face of concerns about its work monitoring communities, cities, and enabling data sharing across law enforcement agencies.

As a sign of that backlash, as Langley spoke on stage, a protest against Flock was taking place outside of Moscone West in San Francisco.

TechCrunch’s Equity podcast team took over the Builders Stage Tuesday morning to tackle a growing challenge for the AI industry: What happens when AI agents go off-script, and who’s responsible for keeping them in check?

Recent incidents, from Anthropic pulling internal evaluations off the live internet after agents misbehaved to Microsoft CEO Satya Nadella calling for an “emergency brake” on AI models, have brought agent security into focus. The Equity team unpacked whether the problem calls for better engineering, new regulation, or both, and why startups are raising millions to secure AI agents.
