This unique work from acclaimed author Dr. Paul Marino (Marino's The ICU Book, The Little ICU Book) challenges the traditional notion that the human body thrives on oxygen, and that promoting tissue oxygenation is necessary for promoting life. This concept fails to recognize that oxygen is a destructive molecule that also damages the human body.  Instead of welcoming oxygen, the human body limits exposure of the tissues to oxygen, and employs an army of chemical antioxidants to combat the damaging effects of oxygen.  This "oxygen protective? human design represents a new paradigm for the relationship between oxygen and human survival, and it has important implications for the excessive and unregulated use of oxygen in clinical practice.
