Helium and Oxygen Treatment of Severe Air-Diving--Induced Neurologic Decompression Sickness

Abstract

The results suggest an advantage of helium-oxygen recompression therapy over air-oxygen tables in the treatment of neurologic DCS.

Prognostic Factors of Spinal Cord Decompression Sickness in Recreational Diving: Retrospective and Multicentric Analysis of 279 Cases

“…The efficiency of these tables seems similar to that of the US Table 6 when a nitrox or heliox mixture is used [2]. For Shupak et al, clinical recovery after the first hyperbaric treatment would tend to be better with a heliox CX30 table, compared to a US Navy Table 6, but final outcome at discharge was not different between these two procedures [7]. Several surveys showed also that deeper recompression at 6 ATA, initially completed with air, was not more successful than USN Table 6 [8,9].…”

“…However, only a few studies that compare 100% oxygen tables at 2.8 ATA to other treatment tables using extended and deeper recompression at 4-6 ATA with oxygenhelium or oxygen-nitrogen mixtures, are available [7][8][9], and do not lead to conclusions on the optimal DCS recompression strategy.…”

“…D'autres tables thérapeutiques utilisant des recompressions plus profondes à 4 ou 6 ATA (30 ou 50 mètres) avec utilisation de mélanges respiratoires suroxygénés utilisant de l'azote ou de l'hélium comme gaz diluants sont également employées dans certains centres hyperbares. À ce jour, il n'existe aucune étude qui ait pu montrer la supériorité d'une table sur les autres en termes de récupération clinique [35,36]. Dans notre pratique, le choix de la table thérapeutique hyperbare tient compte du délai d'arrivée au centre hyperbare, de la sévérité des signes cliniques et de leur évolution dans le temps depuis les premiers soins sur place.…”

The Role of Vestibular Testing in the Evaluation of Patients Engaged in Occupations in Non-Terrestrial Conditions

“…The purpose of hyperbaric oxygen treatment is to alleviate tissue ischaemia and mechanical damage. This is achieved by reducing the size of inert gas bubbles in accordance with Boyle's law, and by increasing the gradient for the diffusion of inert gas from bubbles and tissue out of the body, while the diffusion gradient for oxygen to the ischaemic areas is increased [33,34].…”
