Zero point survey. A framework for optimizing non-clinical processes before and during the code stroke (adapted from Reid et al.) [6]. Self-check refers to mental and physical readiness (stress and fatigue awareness, eating/elimination). While full mental readiness may not be possible at all times, small measures such as nourishment, purposeful attention to one’s physiology (breathe, talk, see, focus) can help optimize personal performance, reduce stress, and achieve additive marginal gains [29]. With each code, using this framework can achieve incremental preparedness, especially during protected codes, where additional steps and personal protective equipment are required. Role clarity, attention to the environment/patient, sharing the mental model are each key ingredients of crisis resource management. ABCDE, airway, breathing, circulation, disability, exposure
