SCUBA diving has several risks associated with it from breathing air under pressure--nitrogen narcosis, barotrauma and decompression sickness (the bends). Trimix SCUBA diving involves regulating mixtures of nitrogen, oxygen and helium in an attempt to overcome the risks of narcosis and decompression sickness during deep dives, but introduces other potential hazards such as hypoxia and oxygen to...

Decompression sickness is a group of pathological processes occurring in the body, following its exposure to an excessive drop in atmospheric pressure. The paper presents a case of a 62-year-old patient with no substantial disease history, a long-standing professional military pilot who was diagnosed with multifocal, bone manifestation of decompression sickness during the diagnosis of right kne...

BACKGROUND Many occupational diving groups have substantially different diving patterns to those for which decompression schedules are validated. AIMS To evaluate tuna farm occupational diving practice against existing decompression models and describe a method for collecting and modelling self reported field decompression data. METHODS Machine readable objective depth/time profiles were ob...

Cmt Kennedy K. S. 1974. General history ot vestibular disorders in diving. Undersea Biomed. Res. ^rC '(I): 73-81.-The history of vestibular symptomatology in hyperbaria is reviewed. Most of this literature deals with vertigo as a symptom of decompression sickness in divers and caisson workers, although other symptoms (e.g. nystagmus, staggers), other influences (compression, mixed gases), and o...

Common anatomical defects of the heart were identified as risk factors for decompression sickness in the 1980s. Between 17% and 35% of the normal population are found to have an anatomical atrial septal defect, or patent foramen ovale (PFO), beyond infancy (1). The incidence among divers who have suffered from serious neurological decompression sickness symptoms was reported to be as high as 61...

INTRODUCTION A large discrepancy exists between ground-based estimates of decompression sickness (DCS) incidence during simulated extra-vehicular activity (EVA) and actual reports of DCS from EVA crewmembers. The discrepancy could be due to the effect of gravity during ground-based DCS studies. The lack of weight-bearing loads (sometimes named adynamia) will relieve pressure within the joints, ...

An investigation of 55 bridge construction workers is reported. The overall bends rate was 097 %. (The term 'bends' as used in this study is defined in the paper.) Chokes were encountered in 67-27% of workers. A cli...

Undersea Hyperb Med 2007; 34(2):99-105.The presence of gas bubbles in the vascular system is often considered a sign of decompression stress and several studies in the existing literature have addressed the relationship between the amount of bubbles detected by u...
