Coma traces part I. First of three recordings from a female patient following cardiac arrest. This one was obtained 33 hours after the arrest and the patient was being ventilated but needed no muscle relaxant or respiratory depressant. Occasional spontaneous eye openings occurred but not to command. Pupils were bilaterally pinpoint; there were no spontaneous movements of arms or legs, and no clinical response to painful stimuli. About half way through the example there was an abrupt change of state from near constant theta activity to an attenuation between theta and alpha bands.
