When should you call 911 according to the FAST method?

Calling 911 when the last well time is known is crucial in the context of the FAST method, particularly for identifying and responding to a stroke. The FAST acronym stands for Face drooping, Arm weakness, Speech difficulties, and Time to call 911. Time is a critical factor in the treatment of strokes because certain interventions, such as administering tPA (a clot-busting drug), are most effective when given within a specific time window from the onset of symptoms. Knowing when the patient was last normal allows emergency responders and medical personnel to make informed treatment decisions upon arrival and during transport.

Recognizing the importance of time in stroke management highlights why knowing the last well time is essential for effective and timely care. Early intervention can significantly enhance outcomes, making it vital for bystanders to act quickly and call emergency services once stroke symptoms are identified.
