Abstract
Prehospital care is fast paced and imposes cognitive demands that may affect patient safety. Functional near-infrared spectroscopy (fNIRS) has been used to measure cognitive activity based on changes of oxygenated and deoxygenated hemoglobin concentrations in the brain. We demonstrate the use of fNIRS to identify and characterize cognitively demanding events in the dynamic clinical environment of emergency medical services teams.
