Closure Rationale

While DCS research and operational development is of high importance, this work is now funded by organizations other than HRP, in a collaborative joint effort. Details of DCS-related work that is already being done (or planned to be done) may be found in the comprehensive NASA technical paper “Integrated Extravehicular Activity Human Research and Testing Plan” (NASA/TP-2019-220232). As part of HRP’s new strategy, it will contribute to these operational efforts as needed.

Description

Initial state:
There are DCS treatment protocols for altitude DCS that involve hyperbaric oxygen treatment. These treatment protocols are based on the aviation scenarios and assume a crewmember’s return to ground. In space, this may not be possible and we need to understand the capabilities of treating DCS with the use of expected in-situ resources.

Additionally, we need to consider if there are any long term outcomes of spaceflight DCS that need to be followed over the course of a crew member’s life.

Approach:

The primary goal is to prevent spaceflight DCS, but should it occur, we need to know how to treat it and if it needs lifetime surveillance. There are aerospace databases to mine for DCS treatment data, which is the first step. Also of importance will be to communicate with other agencies to determine how they are monitoring for long term effects of DCS.
