Reaktionsfähig

Reaktionsfähig is a German adjective meaning capable of reacting or responding to stimuli. It derives from the noun Reaktion (reaction) and the suffix -fähig (able), and is used to describe a subject or system that can mount a response.

In medical and clinical contexts the term is common. It is used to describe a patient who is responsive to verbal or physical stimuli and capable of following commands, as opposed to being unconscious or unresponsive. For example, a patient who is reaktionsfähig may respond to questions, move limbs on instruction, or show reflexive reactions. The term helps convey a level of consciousness and sensorimotor ability, particularly in triage, neurological examination, and assessments of brain function.

In psychology and everyday language, reaktionsfähig denotes the ability to respond appropriately to environmental cues, stressors, or changes in a situation. It can relate to situational adaptability, decision-making, or social interaction, though more precise terms are often used in research.

Outside medicine the term is less standardized. In chemistry or engineering, it is rarely used and may be ambiguous; more common expressions describe whether a system is reactive, responsive, or has been prepared to undergo a reaction. When used, reaktionsfähig should be clarified by context to avoid misinterpretation.

In sum, reaktionsfähig primarily denotes the capacity to respond, most often in medical contexts, with broader but less standardized usage in other fields.
