Abstract: Half of the deaths during Operations Iraqi Freedom and Enduring Freedom due to potentially survivable injuries were caused by noncompressible hemorrhaging. Photoplethysmography can diagnose this condition well before it becomes critical, without the use of magnetic resonance imaging, computed tomography scans, or ultrasound imaging. Remote photoplethysmography (rPPG) offers the possibility of doing this with a single webcam rather than a specialized piece of equipment that must be worn by the Soldier being monitored. rPPG may also be used to monitor other individual vital signs. This technical note examines state of the art for rPPG along with some actual and potential applications.
