What is the purpose of the 'Time last seen normal' in the GFAST acronym?

The 'Time last seen normal' in the GFAST acronym serves a critical role in identifying the onset of stroke symptoms. This time reference is crucial for medical personnel because it helps determine the window of opportunity for certain treatments, such as thrombolytics, which are most effective when administered within a specific timeframe from when the patient was last known to be normal.

By establishing this specific time, healthcare providers can make informed decisions about the urgency of interventions and the types of therapies that might be appropriate. In cases of stroke, time is of the essence, as early treatment can significantly improve outcomes and reduce long-term disability.

Understanding the onset of stroke symptoms is essential for accurate diagnosis and management, making this component of the GFAST assessment vital for emergency responders.
