This presentation addresses the prebreathe protocol for extravehicular activity (EVA) and reviews the International Space Station protocol for accept and reject limits. Tables are included that list altitude decompression sickness (DCS) symptoms, type II DCS in diving and that compare altitude versus diving DCS. Additional slides review ground-level treatment with 100% oxygen and gas bubble size reduction comparison. Shuttle protocol ground trials were tested to arrive at flight approved flight prebreathe protocols and EVA simulations were developed to model shuttle contingency tasks associated with failures of the payload bay doors and latch mechanisms. Prebreathe exercise and microgravity simulation-enabling research findings are presented. A DCS risk definition is offered and contingency plan processes are outlined. Models of accept/reject limits for protocol trials, prebreathe trials, and shuttle 10.2 psi staged protocol are provided.
