Med Device Monday: Converting Anesthesia Waste into a Renewable Resource

We took last week off for the Labor Day holiday, but we're back! And we're extending our August post theme of cool but not-yet-FDA-approved medical devices in order to feature one last device that we just couldn't resist sharing.

Technology in medical devices is a topic we are very interested in around here. There are so many different ways that technology can be used to make patients healthier and procedures safer. Today, we're looking at a different side of things and talking about one way that technology can turn waste from medical procedures into a renewable resource. Pretty cool, right?

Resthetics is a company working with the Texas Medical Center Accelerator (TMCx), as are all of our devices featured in August. Their device essentially recycles waste anesthetic gas into anesthetic gas that can safely be used in future procedures, in a more cost-effective and environmentally friendly way than producing the same anesthetics from raw materials. What's not to like about that?

Per Resthetics, "In 2015, 2.7 million liters of fluorinated anesthetics were released into the atmosphere from United States hospital operating rooms alone. This equates to $1.5 billion worth of wasted anesthetic gas. Fluorinated anesthetics, a type of hydrofluorocarbon (HFC) are potent greenhouse gases and are 4,000 times more harmful than carbon dioxide emissions. They are highly stable and can remain in the atmosphere for up to 20 years, thus contributing to global warming."

So not only would recycling these gasses represent a huge cost savings (which would hopefully be passed on to patients), but it would help the environment. And isn't that the best for everyone's health in the long run?
