Oxygen: the two-faced elixir of life.

- Abstract
Take a moment and consider our planet without oxygen. Imagine the earth some 2.5 billion years ago when oxygen first appeared as a waste product of early anaerobes. Oxygen, as we know it today, is essential for life. Abundant and relatively inexpensive to manufacture, oxygen has widespread use in industry and healthcare. Anesthesia providers routinely administer oxygen in concentrations exceeding that in ambient air to ensure clinical safety and to offset the predictable sequelae associated with patient, drug-related, and procedural factors. Understanding the history of this unique element is critical in evaluating the often contentious body of contemporary research that has illuminated its efficacy (as elixir) and its attendant complications (its 'two-faced' nature). Of particular interest is its role in free radical formation as etiogenic in developing complications. Oxygen is a mainstay in the perioperative management of patients, but its administration should be guided by thoughtful and rational goal-directed outcomes to maximize efficacy and minimize complications associated with its use.
