This study compared neuroendocrine and psychomotor
responses in divers (d, n=11) and non-divers (Nd, n=9)
following 30-minute hyperbaric and decompression stress
to 180, 300, and 450 kpa. Venous blood was drawn pre-
dive and at 20 and 60 minutes post-dive and analyzed for
norepinephrine (Ne), epinephrine (e), tryptophan (trp),
cortisol (cor), growth hormone (gH),
adrenocorticotrophic hormone (actH), and prolactin (prl).
Reaction time was assessed using a psychomotor

This review discusses topics about the relationship
between muscle activity, decompression, and
microgravity. It also provides, in the context of altitude
decompression, an overview of the role of
denitrogenation, metabolic gases, gas micronuclei,
stabilization of bubbles, biochemical pathways activated
by bubbles, nitric oxide, oxygen, anthropometric or
physiological variables, Doppler-detectable bubbles, and
potential arterialization of bubbles.

The preconditioning of divers to reduce post-dive de-
compression sickness (DCS) has gained increased interest
in diving medical research over the last few years. The
beneficial effects of physical exercise, oxygen breathing,
hyperbaric exposure, heat exposure, hyper-hydration, or
nitroglycerin administration before the dive are only a few
examples of ongoing research. In this work, the authors
investigated the effects of pre-dive whole-body vibration
on post-dive bubble formation.

This study aims to determine the potential risk factors
associated with the development of severe diving-related
spinal cord decompression sickness (DCS).

This UK HSE document is a review of diver noise exposure
encompassing diver hearing, noise sources, exposure
levels, and control measures.
This document, which takes into account other studies
available in our database can be considered one of the
most appropriate and easiest to implement. It can be

Progressive elevations in circulating annexin V-coated
(MPs) derived from leukocytes, erythrocytes, platelets, and
endothelial cells are found in mice subjected to increasing
decompression stresses. Individual MPs exhibit surface
markers from multiple cells.
MPs expressing platelet surface markers, in particular,
interact with circulating neutrophils, causing them to
degranulate and leading to further MP production.

Last research about decompresion illness and the use of
oxygen highlight the role of free radicals.
The body generates free radicals, reactive oxygen species,
and reactive nitrogen species by various endogenous
systems, exposure to different physiochemical conditions,
or pathological states. A balance between free radicals
and antioxidants is necessary for proper physiological
function. Suppose free radicals overwhelm the body’s
ability to regulate them, and a condition known as
oxidative stress ensues. Free radicals thus adversely alter
lipids, proteins, and DNA and trigger many human

Based on the fact that previous studies revealed a
progressive increase in ventilation during prolonged
immersed exercise, the authors hypothesized that this
increase occurs because of the development of
metabolic acidosis with a concomitant rise in mean
pulmonary artery pressure and that hyperoxia
attenuates this increase.

Persistent airway inflammation with mucus retention in
patients with chronic airway disorders such as COPD and
bronchiectasis may lead to frequent exacerbations,
reduced lung function, and poor quality of life. This study
investigates whether long-term humidification therapy
with high-flow, fully humidified air at 37 °C through nasal
cannulae can improve these clinical outcomes in this
group of patients. On the diving side, this study is to be
linked to the quality of breathing gases and conditions
resulting from airway inflammation.

The authors report a case of a 41-year-old expert diver
who, after a series of brath hold dives (60 to 80s/dive at
20 to 24m of depth for 5 consecutive hours), experienced
vertigo, ringing in the left ear, and confusion, followed by
right arm paresthesia trailed by right hemi-paresis after a
few minutes. After <60 minutes from the emergence of
these symptoms, he was admitted to the emergency unit
of our hospital with less severe clinical features, presenting
only confusion and paresthesia of the right hand.
