Hypobaric decompression

Research and data on altitude exposure, prebreathe, denitrogenation and pressure transitions relevant to aviation, pressure suits and spaceflight.

Scope

Aerospace decompression changes the direction and context of the pressure transition, but many of the physiological questions overlap with diving. OpenDeco connects those literatures without assuming that a model validated in one environment transfers automatically to another.

  • Altitude decompression sickness
  • Hypobaric chamber exposures
  • Prebreathe and denitrogenation protocols
  • Cabin and suit pressure transitions
  • Extravehicular activity pressure preparation
  • Repetitive altitude exposure
  • Hypobaric model validation
  • Cross-domain comparison with diving evidence

What the aerospace programme asks

  1. Which decompression concepts transfer between hyperbaric and hypobaric exposure, and which do not?
  2. How should prebreathe and denitrogenation be represented when comparing protocols?
  3. Which public altitude datasets can support external validation rather than model fitting alone?
  4. How sensitive are conclusions to pressure reference, exposure sequence and endpoint definition?
