A research study evaluating the effects microgravity has on the central microcirculation of the bodies of astronauts and jet pilots will begin in 2020, funded by the German Aerospace Center and with cooperation from Imedos Systems, according to a press release.
Using Imedos’ system for dynamic vessel analysis, the study will take high-precision images of subjects’ ocular fundus as part of parabolic flights to evaluate how retinal vessels behave before, during and after weightless situations.
Pilots and astronauts often experience blood circulation problems on return to Earth, the release said. This study will deliver information on how to better describe the conditions of the bloodstream and circulation while in space.
“The aim of the project is to better understand the physiological adaptation processes of people in so-called borderline situations,” Dr.-Ing. habil. Walthard Vilser, Imedos CEO, said in the release. “We are pleased that our system for dynamic vessel analysis (DVA) can serve the health of crew members before, during and after space missions and flight maneuvers in microgravity.” Imedos is one of six partners on the project.
Christian Jung, MD, PhD, senior physician of the university clinic for cardiology, angiology and pneumology in Düsseldorf, Germany, will manage the study.
