  1. The F-22 Helmet Mounted In-Flight Physiological Monitoring System and Beyond21 May 2014 Lloyd Tripp, Ph.D. Program Manager, Aerospace Physiology & Toxicology 711th Human Performance Wing Air Force Research Laboratory DISTRIBUTION A: Cleared for public release 16 March 2012, RH-12-109304

  2. Background • 16 November 2010, F-22 class A mishap • F-22 pilots are experiencing hypoxic like symptoms in-flight 2010-2011 • Raptor fleet grounded for 4 months (Alaska Dispatch | Sep 20, 2011) • Returned to flight – pilots to wear finger pulse oximeter sensor as part of return to flight (477th Fighter Group November 2011) • Finger pulse oximeter data reliability issues • 711th HPW develops and tests the helmet mounted pulse oximetry system

  3. Transmission vs Reflectance

  4. F-22Uses Wrist Mounted Pulse Oximeter for In-Flight Arterial O2 Monitoring • Commercial off-the-shelf monitoring device • Provides both arterial oxygen saturation and heart rate information • Allows pilots to spot check their oxygen saturation during flight • There are issues with this approach

  5. In-Flight Finger Left Hand vs Right Hand Oximeter Data

  6. Moving the Sensor North of the Heart: Arteries of the Face
