Airman 1st Class Rehanna Payne, a medical technician, uses medical monitoring technology called the Battlefield Assisted Trauma Distributed Observation Kit, or BATDOK, to check the vitals of a patient while she stands in a hallway of the Wright-Patterson Medical Center, Ohio, April 28, 2020. The Air Force Research Laboratory adapted this technology, originally developed for the pararescue community, for medical facilities during the COVID-19 pandemic.
