Feasibility of forehead reflectance PPG for accurate HRV extraction extends technical options; leaves open validation before clinical or field use.
The effectiveness and efficiency of combat medics can be greatly improved by increasing the speed and precision with which physiological information is gathered from wounded soldiers. In this paper we demonstrate the feasibility of extracting accurate heart rate variability (HRV) measurements from photoplethysmographic (PPG) signals recorded by a reflectance-mode pulse oximeter sensor attached to the forehead.
