Principles, concepts, and perspectives for the improvement of decompression procedures: a Neo-Haldanian approach bridging bubble physics and decompression physiology.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: This paper is a narrative review and theoretical perspective presenting principles, concepts, and perspectives for improving decompression procedures. It distinguishes three levels of evidence: established observations, hypotheses with experimental support, and mechanistic scenarios that remain hypothetical. Methods: We organize decompression around two linked dimensions: bubbles as the primary physical event and microparticles (MPs) as a physiological consequence. We hypothesize that a substantial proportion of decompression-related microbubbles originate from pre-existing gas micronuclei associated with active hydrophobic sites (AHS) at three locations: distal arterial, venous, and extravascular. From these assumptions, five bubble scenarios are considered: growth and detachment from distal arterial AHS; growth and detachment from venous AHS; pulmonary bubble filtration; survival of arterial gas microbubbles and their potential target organs; and intravascular bubble development. Physiological factors may generate MPs, endothelial dysfunction, systemic inflammation, and possibly a secondary generation of microbubbles. Results and discussion: The proposed scenarios align with decompression sickness (DCS) pathophysiology across five target organ systems: skin, brain, inner ear, spinal cord, and musculoskeletal tissue. Inflammatory stress appears important for defining post-dive intervals and multiday diving patterns. Designing decompression procedures therefore requires integrating individual variability and dive history; dive characteristics such as rapid ascents, yo-yo diving, and surface decompression; the bubble scenarios triggered during ascent; and accumulated oxidative stress, oxy-inflammation, and endothelial damage that modify susceptibility to DCS. Conclusion: There is no single ultimate decompression algorithm; rather, different strategies reflect different experience, assumptions, and operational contexts.
