Dr. Scott discusses hyperbaric oxygen therapy (HBOT) and its benefits for healing and recovery. He explains that HBOT involves increasing atmospheric pressure and inspired oxygen to drive more oxygen into circulation, which can accelerate healing and optimize health. Dr. Scott differentiates between mild hyperbaric therapy and deep hyperbaric therapy, which vary in the amount of pressure and oxygen delivered. He also discusses the importance of proper breathing techniques and the role of carbon dioxide in vasodilation. In this conversation, Dr. Scott discusses the benefits of vasodilation and how it can be achieved through various methods. He explains that while vasoconstriction can be beneficial in acute situations, chronic issues often require vasodilation.
