In this era of easy self-publishing, and the Amazons and the Flipkarts of the world making even the most arcane of titles within reach, one is spoilt for choices when it comes to reading up on any new topic. Even on something as esoteric as HBOT there are tons of books available, you just need to do a search on Amazon (the US site amazon.com, not the Indian site amazon.in).
But if there is just one book you would like to read to update yourself on HBOT, look no further than The Oxygen Revolution by Paul G Harch, MD, and Virginia McCullough.
In the US, pretty much nothing can happen in the healthcare world without the approval of the FDA (Food & Drug Administration). FDA has approved HBOT for 14 medical conditions. But Dr Harch has extended the frontiers of oxygen therapy much beyond what is officially "approved". In this sense, he has been a real pathbreaker.
As a part of our outreach and professional education programme, we are thinking of making this book available in India in an affordable 'economy' edition.
