What does the term 'sustained' refer to in a medical context?

In a medical context, the term 'sustained' refers to a condition or state that is continuous and maintained over a period without interruption. This meaning is crucial in various healthcare scenarios, such as in monitoring a patient’s vital signs, where sustained readings indicate stability or ongoing concern. For instance, sustained high blood pressure or sustained pain levels may require ongoing assessment and potentially intervention.

The other options suggest different meanings that do not align with the definition of 'sustained.' Intermittent implies a pattern that includes breaks or pauses, which contrasts with the continuous nature that 'sustained' indicates. Short-term refers to something that lasts for a brief duration, also opposite to the idea of something being sustained over time. Gradual suggests a slow increase or change rather than a consistent state, further distinguishing it from the meaning of 'sustained.' Understanding 'sustained' as continuous without interruption is essential for healthcare professionals to effectively communicate and manage patient care.
