R96.0: Instantaneous death

Instantaneous death, also identified as sudden death in the realm of medical science, implies to a swift and unexpected cessation of both heart and respiratory functions, consequently leading to an abrupt loss of consciousness and vital signs. It’s a condition marking the abrupt and unanticipated termination of life. Generally, this could occur due to a varied range of causes including fatal heart conditions like cardiac arrest or fast-developing diseases such as aggressive infections or a severe injury. Instantaneous death is identifiable by a lack of signs of life such as absence of pulse, conscious activity or breathing. It's essential to understand that this is an outcome and not a disease itself, meaning that it ensues from other primary medical conditions or traumas.
