CFAM1 trace. The markers at the top represent 1 minute intervals.
Coma trace, part II. This trace was obtained some 58 hours following cardiac arrest and the patient showed some clinical improvement in as much as she made decerebrate responses to painful stimuli. There has been an increase of trace amplitude and a shift towards higher frequencies compared to the previous record. At (1) there was a respiratory obstruction followed by an increase of amplitude and the appearance of beta band activity. The patient became cyanosed. At (2) the obstruction was cleared and the patient re-oxygenated. This was followed by a fall of amplitude and a reduction of beta band activity. Delta band activity began to increase before the attenuation of beta. Over the next 20 minutes the trace amplitude recovered and there was a shift towards higher frequencies.
