Recognizing a Stroke - Three Commands for the Victim
Three commands sometimes used by doctors to begin assessing whether a person may be experiencing a stroke can also be useful for people who are not doctors, according to a study by University of North Carolina researchers.
Lay persons can command a potential stroke victim to:
The three commands, known as the Cincinnati Prehospital Stroke Scale (CPSS), are used by health professionals as a simple first step in the assessment process for signs of stroke. If a person has trouble with any of these simple commands, emergency services (911) should be called immediately with a description of the situation, noting that you suspect the individual is having a stroke.
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. According to the U.S. National Institute of Neurological Disorders and Stroke, the five major signs of stroke are the sudden onset of:
The physicians at UNC showed in a small study that lay persons can effectively recognize the signs of stroke using the CPSS assessment. While this study was funded by the American Stroke Association (ASA) and its results presented at their 2003 International Stroke Conference, the ASA has not taken an official position on recommending the use of the CPSS by lay persons due to the small size of the preliminary study.
In any case, should a person experience any of the signs of stroke or be unable to complete the three simple tasks, emergency services should be notified immediately. Both the death rate and level of disability resulting from strokes can be dramatically reduced by immediate and appropriate medical care.
