Episode 048 -- Hyperbaric Oxygen Therapy with Dr. Michael Bennett

Stroke recovery is a marathon; it's not a sprint. Regaining cognitive skills, physical skills, sensory skills, and more takes time and work. During that time, life can be really hard and unpleasant for many folks. The may or may not be able to work. Relationships get turned upside down, and after a while you just want it to go away. Surely, with all the advances in medicine, there must be something…some fancy technology or machine…some magic technique that will fix these problems, right?

That leads folks to look for and explore alternatives. It also means that many survivors start pursuing things that don't work. Hyperbaric oxygen therapy appears to be one of those therapies. In Hyperbaric Oxygen Therapy, the patient spends time in a pressure chamber where the air pressure is 2-3X normal and breathes pure oxygen. They get roughly 8-12X as much oxygen as in their normal lives. This, supposedly, should grow new blood vessels in the brain and revive the dead neurons that were killed by the stroke, or drive new growth through neuroplasticity.

I saw a number of people asking about it in Facebook groups and twitter feeds, so I began talking with folks to learn more. Strokecast regular, neurologist Dr Nirav Shah, introduced me to one of the world's leading authorities on Hyperbaric Oxygen therapy, Dr. Mike Bennett in Australia.

This week I talk with Dr. Bennett about the theory and the research around hyperbaric medicine. We answer the key questions about it -- is it safe, and does it work.

The short version is that it is mostly safe, but there is no reliable research demonstrating that it works. The main risk is to the patient's wallet.

Hack of the Week -- Rocker Knife

One handed steak knifeLast week, I talked about cutting meat at a restaurant -- don't. This week, let's talk about doing the same thing at home where you may not have a kitchen staff. Sure, at home you can just pick up a hunk of meat with your hands. But sometimes you still want to slice it for some reason.

I use a Verti-Grip knife. It's designed for folks with use of one hand. I hold it in my fist, rock it against the meat, and it cuts right through. It doesn't require you to brace what you're cutting with a fork. For a $14 gadget, it works really well.



Pure Mind Magic

A few months back, German podcaster, magician, and mindset expert Victoria Mavis joined me to talk about the intersection between public speaking and magic on my other podcast, 2-Minute Talk Tips. You can find that interview at 2-MinuteTalkTips.com/magic.

During December, I had the pleasure of appearing on her show, Pure Mind Magic. We talked about speaking, sure, but much of the conversation was about my stroke story and the power of mindset in recovery.
