Space Medicine research
Our Space Medicine research Space2Breathe focuses on applying and developing medical knowledge and tools for use in space. The space sector is advancing at a rapid pace, and so far, the medical world has struggled to keep up. The space environment, whether in orbit or on other planets, introduces new medical challenges that need to be thoroughly investigated. Think of developing emergency medical protocols for use in space, or studying how the human body changes when exposed to the space environment.
Current Research
We are currently focused on developing training programs and protocols for a surgical airway procedure used in emergencies where a patient cannot breathe normally. In this procedure, access to the airway is created by making a small opening in the front of the throat, through which a breathing tube is inserted.
Why This Research Matters
The studies we conduct are essential for protecting the safety of astronauts. Beyond that, they also deepen our understanding of health and disease here on Earth. Research into medical emergencies in space, for example, is directly relevant to other remote and isolated environments, such as climate research expeditions or maritime voyages, where access to advanced medical care is equally limited.
How we conduct our research
The training programs and protocols for this emergency airway procedure are being developed across several separate studies. We train both non-medically trained participants and medical experts to perform the procedure. They then carry it out underwater, which is a reliable method for simulating weightlessness.
Once the protocol has been optimized, it will be tested by astronauts during a parabolic flight. In this type of flight, weightlessness is achieved by sending the aircraft into freefall for short periods of time. This allows the procedure to be validated under conditions of true weightlessness.

Participating hospitals
This research is conducted by Radboud University Medical Center, in collaboration with the Netherlands Aerospace Centre. The work is carried out within the Department of Ear, Nose and Throat Surgery, and is supported by the Jan Jongbloed Fund.
