If the apocalypse is going to happen, now seems like the time. From hybrid killer bees to domestic terrorism, catastrophe bingo has displaced baseball as America's pastime. No one seems to have a strategy. Until now. Like our modern world, the discipline of anesthesiology is filled with long periods of stressful uncertainty interrupted by unpredictable catastrophes. Vigilance shares how anesthesiologists utilize statistical thinking, cognitive psychology, and behavioral economics to generate stability and prevent complications in the operating room-and how these same strategies apply to our broader systemic problems. Anesthesiologists have perfected their methodology over the last seventy years. Death from anesthesia complications has fallen more than 98 percent despite increasing patient and surgical complexity. Learn how to recognize the invisible synergistic systems that control our modern world, how to intervene decisively when disasters happen, and how to manage sudden catastrophes to prevent harm. Vigilance is a guide for thriving in our new, uncertain world.
