How to Measure Fatigue

People in pipeline control centers are supposed to be trained to recognize the signs and effects of fatigue.  When they ask me how to do that, I reply it is very difficult without using probes to measure heart rate, blood pressure, temperature or using eye scan tests with an alertness test.  Australian researchers wrote a journal article about their research using changes in speech to recognize fatigue.   Measuring Fatigue Through the Voice – Digital Journal

Since other research indicates that a fatigued person performs similarly to an intoxicated person, I suppose slurred speech in the sleep deprived could be similar to someone who has high blood alcohol content.

We have to rely on physical symptoms to assess someone’s level of fatigue.

• Yawning repeatedly
• Heavy eyelids or microsleeps
• Eye-rubbing
• Nodding off or head drooping
• Headaches, nausea, or upset stomach
• Slowed reaction time
• Lack of energy,  weakness, or light headedness

If you or a co-worker is exhibiting these signs, he or she is probably fatigued.  If it’s between 2am and 6am and someone has those symptoms.  watch them carefully and monitor their performance.
