1 1 The F-22 Helmet Mounted In-Flight Physiological Monitoring System and Beyond 21 May 2014 Lloyd Tripp, Ph.D. Program Manager, Aerospace Physiology & Toxicology 711 th Human Performance Wing Air Force Research Laboratory DISTRIBUTION A: Cleared for public release 16 March 2012, RH

2 2 Background 16 November 2010, F-22 class A mishap F-22 pilots are experiencing hypoxic like symptoms in- flight 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 (477 th Fighter Group November 2011) Finger pulse oximeter data reliability issues 711 th HPW develops and tests the helmet mounted pulse oximetry system

3 3 Transmission vs Reflectance

4 4 F-22 Uses Wrist Mounted Pulse Oximeter for In-Flight Arterial O 2 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 5 In-Flight Finger Left Hand vs Right Hand Oximeter Data

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

7 7 Helmet Ear Cup Integrated Pulse Oximetry 1990’s Peel and Stick Oxisensor Silicon Ear Cup Integrated Oxisensor OUCH!!!

8 Helmet Ear Cup Integrated Oxisensor: F-22 SAB 120 Day Challenge: 15 Nov 2011 Oxisensor 8

9 Helmet Mounted Cerebral and Arterial O2 Saturation During Simulated Aerial Combat Maneuver Tripp, Chelette, Savul, & Widman,

10 Helmet Mounted Pulse Oximeter: RH + USAFSAM + HSI + NAMRU-D + F-22 SPO + AFRL/RY + Industry = Integrated Human Performance Solutions Data Collection EMI/EMC NVG Cockpit/User Survivability Emergency Descent Maintainability Training Acoustic Evaluation Centrifuge Test Survivability Wind Blast Safety In-House Prototype Fabrication
