Abstract：
This article addresses a common yet rarely discussed aspect of hospital care-a pro-active approach to ethical dilemmas. Potential ethical conflicts often present warning signs to clinicians, analogous to the warning lights on a car\'s dashboard. Using a recent case study, a commonly encountered clinical decision-a conflict about whether to terminally extubate a critically ill patient versus whether to offer a tracheostomy-we describe a pro-active approach to ethical conflicts and outline three learning objectives: (1) the need for a robust understanding of the term \"futility,\" (2) the need for an appreciation the various and often conflicting interpretations of \"improved/improving,\" and (3) the need to understand the challenges of surrogate decision making.
