2nd Lt. (Dr.) Dominique O’Brien, Project Lead, Airman Sensing and Assessment Product Line, with the 711th Human Performance Wing’s Airman Systems Directorate, displays two devices her team used during flight tests in support of a request from the 20th Fighter Wing to provide assistance with assessing cabin pressure, oxygen concentrations, and possible hypoxia-like symptoms reported by their F-16 pilots. One device is called the “Slam Stick,” (orange in color), which measures tri-axial acceleration – or acceleration in all three axes, X, Y, and Z. The second device is called the Insta Pilot Breath Air Monitor, or IPBAM, (black device being held by Lt. O’Brien) which measures several critical parameters of the breathing gas delivered to the pilot. (U.S. Air Force photo/Bryan Ripple)
