Brain death is a critical medical condition where the brain ceases to function, leading to the irreversible loss of all brain functions, including consciousness and brainstem reflexes. Detecting brain death is a complex process that requires a systematic approach to ensure accurate diagnosis. The Brain Death Checklist is a vital tool used by healthcare professionals to guide them through the evaluation process. This checklist consists of essential items and steps that help confirm the absence of brain activity, which is crucial for determining organ donation eligibility and making end-of-life decisions.
