It is generally accepted that the incidence of decompression sickness (DCS) from hyperbaric exposures is low when few or no bubbles are present in the circulation. To date, no data are available on the influence of in-water oxygen breathing on bubble formation following a provocative dive in man. The purpose of this study was to compare the effect of post-dive hyperbaric versus normobaric oxygen breathing (NOB) on venous circulating bubbles. Nineteen divers carried out open-sea field air dives… Expand
Effect of in-water oxygen prebreathing at different depths on decompression-induced bubble formation and platelet activation.
TLDR
The data show that prebreathing oxygen, more effective with HBO than NBO, decreases air bubbles and platelet activation and, therefore, may be beneficial in reducing the development of decompression sickness. Expand
Oxygen breathing or recompression during decompression from nitrox dives with a rebreather: effects on intravascular bubble burden and ramifications for decompression profiles
TLDR
The results tend to demonstrate that the “oxygen window” plays a key role in the reduction of bubble production and that breathing pure oxygen during decompression stops is an optimal strategy to prevent decompression sickness for nitrox diving. Expand
Effect of oxygen-breathing during a decompression-stop on bubble-induced platelet activation after an open-sea air dive
TLDR
Primary oxygen-decompression stop could reduce bubble-induced platelet activation and the pro-coagulant activity of PMP release preventing the thrombotic event in the pathogenesis of decompression sickness. Expand
Influence of oxygen enriched gases during decompression on bubble formation and endothelial function in self-contained underwater breathing apparatus diving: a randomized controlled study
TLDR
Nitrox 99 reduced bubble formation, did not change post-dive FMD, and decreased total dive duration, indicating that it might better preserve endothelial function compared with air and nitrox 50 dive protocols. Expand
Comparison of tissue oxygenation achieved breathing oxygen using different delivery devices and flow rates.
TLDR
The NRB was rated as the most comfortable to wear, easiest to breathe with, and overall the easiest to use of the commonly available devices promoted for O₂ delivery to injured divers. Expand
Decompression Illness in Repetitive Breath-Hold Diving: Why Ischemic Lesions Involve the Brain?
Nitrogen (N2) accumulation in the blood and tissues can occur due to breath-hold (BH) diving. Post-dive venous gas emboli have been documented in commercial BH divers (Ama) after repetitive divesExpand
Hyperbaric oxygen treatment reduced the lung injury of type II decompression sickness.
TLDR
The microscopic and ultrastructural findings confirm that the lung is an important organ affected by DCS and confirm that HBO can alleviate DCS-induced pulmonary damage. Expand

TLDR
The results suggest that IWR is effective for severe neurological DCS in remote fishing communities, especially with oxygen. Expand

Divers may be at risk of long-term CNS damage from non-symptomatic hyperbaric exposure. We investigated the effect of severe, controlled hyperbaric exposure on a group of healthy goats with similarExpand
Aerobic demand and scuba diving: concerns about medical evaluation.
TLDR
Increased oxygen partial pressure and cold exposure during scuba diving will additionally increase afterload by vasoconstrictive effects and may induce bradyarryhthmias in combination with breath-holds. Expand

TLDR
It is probably true that the available evidence suggests that treatment at depths shallower than 60 feet runs the risk of failure and that treatments deeper than 60 Feet offers no particular benefit in the majority of cases, but there is really little published data to support use of the other treatments.

O2 pressures between 0.12 and 2.5 atm abs, circulatory function, and N2 elimination.
TLDR
It is concluded that perfusion-dependent N2 elimination decreases secondary to vasoconstriction induced by increasing oxygen pressures, and oxygen breathing during decompression should be performed at the lowest possible ambient pressure compatible with freedom from pathogenic bubble formation.

TLDR
Limiting tissue half times computed from the 20% VGE isopleth suggested that saturation exposures are controlled by a greater sensitivity of the short-half-time tissues than previously appreciated, rather than by additionally extended half times. Expand
