Diving often causes the formation of ‘silent’ bubbles upon
decompression. If the bubble load is high, then the risk of
decompression sickness (DCS) and the number of
bubbles that could cross to the arterial circulation via a
pulmonary shunt or patent foramen ovale increase.
Bubbles can be monitored aurally, with Doppler
ultrasound, or visually, with two-dimensional (2D)
ultrasound imaging. Doppler grades and imaging grades
can be compared with good agreement. Early 2D
imaging units did not provide such comprehensive
observations as Doppler, but advances in technology
have allowed the development of improved, portable,
relatively inexpensive units. Most now employ harmonic
technology; it was suggested that this could allow
previously undetectable bubbles to be observed.

A ketogenic diet (KD) may decrease central nervous
system oxygen toxicity symptoms in divers. In view of this
implication, a feasibility/toxicity pilot study was performed
to demonstrate tolerance of KD while performing normal

The authors hypothesized that the number of blood-
borne, Annexin V-positive Circulating microparticles (MPs)
and neutrophil activation, assessed as surface MPO
staining, would differ between self-contained underwater
breathing-apparatus divers suffering from DCS vs.

Nutritional antioxidants have been proposed as an
expedient strategy to counter the potentially deleterious
effects of scuba diving on endothelial function, flow-
mediated dilation (FMD), and heart function. Sixteen
volunteers performing a single standard dive (20 min at 33
m) according to US Navy diving procedures were
randomly assigned to two groups: one was administered
with two doses of 200 mg of an anthocyanin (AC)-rich
extract from red oranges, 12 and 4 h before diving.

The present study investigated the cognition and
performance efficacy of four divers during a simulated 480
meters helium–oxygen saturation diving. The authors
analyzed the spatial memory, 2D/3D mental rotation
functioning, grip strength, and hand–eye coordination
ability in four divers during the 0–480 m compression and
decompression processes of the simulated diving.
