Whilst astronauts have large spheres of eggs, it is not recommended to carry out thorough examinations or removals.NASA’s expert working group has put together policies to mitigate risks, not only by relying on bubble detection, but also by outbound activity procedures and continuous data collection.
Do not change the selection criteria due to venous blood clots.
NASAThe expert working group conducted an oxygen pre-respiratory test before offshore activities associated with the Artemis project, reduced blood pressure (DCSIn the case of venous blood clots during flight.VTEEggs in the heart (PFOThe impact was considered, based on the recommendation.2024Years ofPFOandDCSThe evaluation,2026years of space flight.VTEdiscussed and updated.DCSPreventive measures are integrated.
In this assessment, PFO was not considered a major risk factor for the formation of VTE. Based on this conclusion, the working group did not recommend changing the selection criteria for astronauts for PFO on the grounds of VTE.
The bubble grade alone cannot predict depression.
The reserve oxygen breathing before offshore activity is carried out to mitigate the risk of DCS associated with reduced pressure.After examining procedures including walking under partial gravity, a decisive relationship between the size of the detected bubble and the risk of DCS at high altitudes has not been confirmed, and the predictive performance in lunar activity has also been determined to be uncertain.

Review the conditions for participating in ground tests and taking medication before and after off-shore activities.
In the ground trials, it was recommended that subjects were not excluded from the study only because the bulbs of LVGE were confirmed.The trial procedures must combine the safety of the subjects and the representation of the target group and fully explain the condition and associated risks of LVGE.
Clear clinical guidelines were also required for medication before after offshore activity. In addition to the use of aspirin for the prevention and reduction of pain of DCS, the guidelines need to address the potential of acetaminophen, ibuprofen, naproxen and selekoxib to conceal the symptoms of DCS.
