From reading the literature on Heart Rate Variability (HRV) use and interpretation, we might be at the stage where we could add the sensors for HRV in healthcare units where unconscious patients are cared for. Thoughts?
Great idea! Ucs responses to emotional stimuli such as familiar voices and significant words would probably alter HRV in comparison to a stable baseline. GSR would work too, or even simple heart rate.
I agree with what you said. I interviewed over 100 patients who previously were reported as once being unconscious. This link, which is a free to view course, has the descriptions of what they experienced. http://www.rnceus.com/course_frame.asp?exam_id=15&directory=uncon.
