Psychophysiologic measures of cognitive load in physician team leaders during trauma resuscitation

作者：

Highlights：

• Physician cognitive load can be quantified during authentic trauma resuscitations.

• Wearable sensors measured gaze, pupil size, galvanic skin response, and heart rate.

• Self-reported cognitive load was assessed via 1st person video debriefing protocol.

• Physiologic and psychometric metrics of cognitive load were variably correlated.

• Integrating several physiologic markers more accurately quantifies cognitive load.
